      "description": "Hourly renewable generation profiles compiled for the Western United States as part of the GridPath Resource Adequacy Toolkit. Profiles are stated as a capacity factor (a fraction of nameplate capacity). There are 3 different levels of processing or aggregation provided, all at hourly resolution: Individual plant (wind) or generator (solar) output, capacity-weighted averages of wind and solar output aggregated to the level of balancing authority territories (or transmission zones for larger balancing authorities), and that same aggregated output but with some problematic individual generator profiles modified such that they match the overall production curve of the balancing authority they are within. This data also contains some daily weather data from several sites across the western US and tables describing the way in which individual wind and solar projects were aggregated up to the level of balancing authority or transmission zone.",

      "description": "Annual time series of Actual rate and removal efficiency for air emissions reported by thermoelectric or combined-cycle power plants with a total steam turbine capacity greater than or equal to 10 megawatts.\n\n\nMost-recent data:\n  2024\n\n\nProcessing:\n  Data has been cleaned but not tidied/normalized. Published only temporarily and may be removed without notice.\n\nSource:\n  EIA Form 923 -- Power Plant Operations Report (Schedule 8C)\n\nPrimary key:\n  This table has no primary key. This table is not yet normalized, and contains information about several different types of emissions control equipment, each of which has its own ID, and not all of which are present at every plant. As a result there is currently no unique, non-null primary key. Conceptually, the primary key should consist of plant_id_eia, report_date, mercury_control_id_eia, nox_control_id_eia, so2_control_id_eia, and particulate_control_id_eia. In practice many records have NULL values for all of the control equipment IDs.\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* This table is experimental and/or a work in progress and may change in the future.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nIn the raw data, the so2_test_date and particulate_test_date columns contained a wide variety of non-standard date formats. They have been standardized to ISO-8601 (YYYY-MM-DD) where possible. Missing days and months have been filled in with 01. A handful of manual spot-fixes have been applied to particularly strange formats. Two-digit years have been assumed to fall between 1950 and the last year observed in the report_date column.",

It is not a cleaned up table - it\nis meant for forensic purposes only. If you have a question about why a value is\nreported in an ``scd``, ``entity`` or ``out`` table, you can find out all of the inputs\nthat were used as ingredients to find the canonical value.

It is not a cleaned up table - it\nis meant for forensic purposes only. If you have a question about why a value is\nreported in an ``scd``, ``entity`` or ``out`` table, you can find out all of the inputs\nthat were used as ingredients to find the canonical value. You can filter by the\ncolumn_name and the entity id to find all of the possible input values.",

It is not a cleaned up table - it\nis meant for forensic purposes only. If you have a question about why a value is\nreported in an ``scd``, ``entity`` or ``out`` table, you can find out all of the inputs\nthat were used as ingredients to find the canonical value.

It is not a cleaned up table - it\nis meant for forensic purposes only. If you have a question about why a value is\nreported in an ``scd``, ``entity`` or ``out`` table, you can find out all of the inputs\nthat were used as ingredients to find the canonical value. You can filter by the\ncolumn_name and the entity id to find all of the possible input values.",

Similarly, ``disposition_to_other_volume_mcf``\n(Line 18.4) is summed from the original granular data and reported as one aggregate field.\n\nThe ``delivered_gas_heat_content_mmbtu_per_mcf`` is expected to be between 0.8 and 1.2\nby the EIA. We find that less than 0.5 percent of data falls outside of these expected bounds.\n\nThe ``total_disposition_mcf`` field includes disposition to consumers which is reported in core_eia176__yearly_gas_disposition_by_consumer.\nNote that the reported total disposition and the sum of values in this table and core_eia176__yearly_gas_disposition_by_consumer often don't match as would be expected.\nThus, we have preserved both the total field and the sub-components in these two tables.",

See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n* Contains information from multiple raw inputs.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis is one of two tables where canonical\nvalues for boilers are set. It contains values which are expected to vary slowly, while\n:ref:`core_eia__entity_boilers` contains those expected to remain fixed.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.\nAll tables downstream of this one inherit the canonical values established here.",

See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nIncludes control ids for sulfur dioxide\n(SO2), particulate matter, mercury, nitrogen oxide (NOX), and acid (HCl) gas\nmonitoring.\n\nThis table inherits canonicalized values for plants and utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

      "description": "Slowly changing dimension (SCD) table describing attributes of generators which may vary from year to year. Compiled from across EIA-860 and EIA-923 data.\n\n\nMost-recent data:\n  2026\n\n\nProcessing:\n  Data has been cleaned and organized into well-modeled tables that serve as building blocks for downstream wide tables and analyses.\n\nSource:\n  EIA Form 860 -- Annual Electric Generator Report\n\nPrimary key:\n  plant_id_eia, generator_id, report_date\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Data has been drawn from several EIA sources which are not always consistent with each other, and PUDL chooses the most consistent or relevant value to facilitate cross-referencing even if that means some values will differ from the raw sources. See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n* Contains information from multiple raw inputs.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis is one of two tables where canonical\nvalues for generators are set. It contains values which are expected to vary slowly, while\n:ref:`core_eia__entity_generators` contains those expected to remain fixed.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.\nAll tables downstream of this one inherit the canonical values established here.",

Compiled from across all EIA-860 and EIA-923 data.\n\n\nMost-recent data:\n  2026\n\n\nProcessing:\n  Data has been cleaned and organized into well-modeled tables that serve as building blocks for downstream wide tables and analyses.\n\nSource:\n  EIA Form 860 -- Annual Electric Generator Report\n\nPrimary key:\n  plant_id_eia, report_date\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Data has been drawn from several EIA sources which are not always consistent with each other, and PUDL chooses the most consistent or relevant value to facilitate cross-referencing even if that means some values will differ from the raw sources. See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n* Contains information from multiple raw inputs.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis is one of two tables where canonical\nvalues for plants are set. It contains values which are expected to vary slowly, while\n:ref:`core_eia__entity_plants` contains those expected to remain fixed.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.\nAll tables downstream of this one inherit the canonical values established here.",

Compiled from all EIA data.\n\n\nMost-recent data:\n  2026\n\n\nProcessing:\n  Data has been cleaned and organized into well-modeled tables that serve as building blocks for downstream wide tables and analyses.\n\nSource:\n  EIA Form 860 -- Annual Electric Generator Report\n\nPrimary key:\n  utility_id_eia, report_date\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Data has been drawn from several EIA sources which are not always consistent with each other, and PUDL chooses the most consistent or relevant value to facilitate cross-referencing even if that means some values will differ from the raw sources. See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n* Contains information from multiple raw inputs.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis is one of two tables where canonical\nvalues for utilities are set. It contains values which are expected to vary slowly, while\n:ref:`core_eia__entity_utilities` contains those expected to remain fixed.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.\nAll tables downstream of this one inherit the canonical values established here.",

Includes\nthe standard (IEEE/other) and other relevant information.\n\nSAIDI is measured in minutes, and represents the sum over the year of all customers interrupted times\nthe number of minutes they experienced an interruption, divided by total number of customers.\n\nSAIFI is measured in customers, and represents the sum over the year of the total number of customers that\nexperienced an interruption, divided by the total number of customers.\n\nThe IEEE standards which can be used to calculate SAIDI and SAIFI include IEEE 1366-2003 and IEEE 1366-2012.\nThese standards define momentary interruptions as having a duration of five minutes or less.\nIf one of these IEEE standards is used, respondents fill out part B and are required to specify:\n\n* SAIDI major event days minus loss of supply\n* SAIFI major event days minus loss of supply\n\nSAIDI and SAIFI major event days minus loss of supply excludes events where the reliability event resulted\nfrom an event on the distribution system, not from the high-voltage system. The voltage that distinguishes\nthe distribution system from the supply system is given in ``highest_distribution_voltage_kv``.\n\nIf a method other than these IEEE standards is used for calculating SAIDI and SAIFI indexes, respondents\nfill out part C and are required to specify:\n\n* whether inactive accounts are included\n* how they define a momentary interruption (less than 1 minute, less than or equal to 5 minutes, or other)\n\nIn this table, column ``standard`` is \"ieee_standard\" for respondents who have filled out part B, and\n\"other_standard\" for respondents who have filled out part C.",

The same coalmines report many individual\ndeliveries, and repeating their attributes many times in the fuel receipts and costs\ntable is duplicative. Unfortunately the coalmine attributes do not generally use a\ncontrolled vocabulary or well defined IDs and so in practice there are many distinct\nrecords in this table that correspond to the same mines in reality.\n\nWe have not yet taken the time to rigorously clean this data, but it could be linked\nwith both Mining Safety and Health Administration (MSHA) and USGS data to provide more\ninsight into where coal is coming from, and what the employment and geological context\nis for those supplies.",

      "description": "Individual fuel deliveries to power plants, organized by fuel type and supplier.\n\n\nMost-recent data:\n  2025\n\n\nProcessing:\n  Data has been cleaned and organized into well-modeled tables that serve as building blocks for downstream wide tables and analyses.\n\nSource:\n  EIA Form 923 -- Power Plant Operations Report (Schedule 2 - Part A)\n\nPrimary key:\n  This table has no primary key. Each record describes an individual fuel delivery. There can be multiple deliveries of the same type of fuel from the same supplier to the same plant in a single month, so the table has no natural primary key.\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Date column arbitrarily uses the first of the month.\n\n* Some values have been redacted.\n\n* Time of fuel deliveries is not necessarily connected with time of fuel consumption.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThere can be a significant delay between the receipt of fuel and its consumption, so\nusing this table to infer monthly attributes associated with power generation may not be\nentirely accurate. However, this is the most granular data we have describing fuel\ncosts, and we use it in calculating the marginal cost of electricity for individual\ngeneration units.\n\nUnder some circumstances utilities are allowed to treat the price of fuel as proprietary\nbusiness data, meaning it is redacted from the publicly available spreadsheets. It's\nstill reported to EIA and influences the aggregated (state, region, annual, etc.) fuel\nprices they publish. From 2009-2021 about 1/3 of all prices are redacted. The missing\ndata is not randomly distributed. Deregulated markets dominated by merchant generators\n(independent power producers) redact much more data, and natural gas is by far the most\nlikely fuel to have its price redacted. This means, for instance, that the entire\nNortheastern US reports essentially no fine-grained data about its natural gas prices.\n\nAdditional data which we haven't yet integrated is available in a similar format from\n2002-2008 via the EIA-423, and going back as far as 1972 from the FERC-423.",

Fuel quantity is reported in standard\nEIA fuel units (tons, barrels, Mcf). Heat content per unit of fuel is also reported,\nmaking this table useful for calculating the thermal efficiency (heat rate) of various\ngeneration units.\n\nThis table provides better coverage of the entire fleet of generators than the\n``core_eia923__monthly_generation_fuel`` table, but the fuel consumption reported here is not directly\nassociated with a generator. This complicates the heat rate calculation, since the\nassociations between individual boilers and generators are incomplete and can be\ncomplex.",

We use\nthe primary fuels and prime movers reported for each generator along with their\ncapacities to attribute fuel consumption and generation when it isn't directly reported\nin the ``core_eia923__monthly_generation`` and ``core_eia923__monthly_boiler_fuel`` tables in order to calculate\ncapacity factors, heat rates, and the marginal cost of electricity.\n\nThe table makes a distinction between all fuel consumed and fuel consumed for\nelectricity generation because some units are also combined heat and power (CHP) units,\nand also provide high temperature process heat at the expense of net electricity\ngeneration.",

      "description": "Hourly time series of balancing authority net generation, interchange, and demand.\n\n\nMost-recent data:\n  2026\n\n\nProcessing:\n  Data has been cleaned and organized into well-modeled tables that serve as building blocks for downstream wide tables and analyses.\n\nSource:\n  EIA Form 930 -- Hourly and Daily Balancing Authority Operations Report\n\nPrimary key:\n  datetime_utc, balancing_authority_code_eia\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nNet generation represents the metered output of electric generating units in a BA's electric system. This generation only includes generating units that are managed by a BA or whose operations are visible to a BA.\n\nGenerators on the distribution system\u2014both large-scale resources and small-scale distributed resources, such as rooftop solar photovoltaic (PV) systems\u2014are typically not included.\n\nIn some electricity publications, EIA reports generation from all utility-scale\ngenerating units in the United States. BAs only meter generating units that are from a subset of all utility-scale generating units. As a result, when hourly generation from the EIA-930 is aggregated to monthly or annual levels, the results will be lower than monthly and annual aggregations in other EIA electricity publications.\n\nInterchange is the net metered tie line flow from one BA to another directly\ninterconnected BA. This table includes the net sum of all interchange occurring between a BA and all of its directly interconnected neighboring BAs. For a detailed breakdown of interchange between each pair of adjacent BAs see\ncore_eia930__hourly_interchange.\n\nNegative interchange values indicate net inflows, and positive interchange values indicate net outflows.\n\nDemand is a calculated value representing the amount of electricity load within a BA's electric system. A BA derives its demand value by taking the total metered net electricity generation within its electric system and subtracting the total metered net electricity interchange occurring between the BA and its neighboring BAs.\n\nEach BA produces a day-ahead electricity demand forecast for every hour of the next day. These forecasts help BAs plan for and coordinate the reliable operation of their electric system.",

See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n* Contains information from multiple raw inputs.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis is one of two tables where canonical\nvalues for boilers are set. It contains values which are expected to remain fixed, while\n:ref:`core_eia860__scd_boilers` contains those which may vary from year to year.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.\nAll tables downstream of this one inherit the canonical values established here.",

See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n* Contains information from multiple raw inputs.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis is one of two tables where canonical\nvalues for generators are set. It contains values which are expected to remain fixed, while\n:ref:`core_eia860__scd_generators` contains those which may vary from year to year.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.\nAll tables downstream of this one inherit the canonical values established here.",

See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n* Contains information from multiple raw inputs.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis is one of two tables where canonical\nvalues for plants are set. It contains values which are expected to remain fixed, while\n:ref:`core_eia860__scd_plants` contains those which may vary from year to year.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.\nAll tables downstream of this one inherit the canonical values established here.",

See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n* Contains information from multiple raw inputs.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis is one of two tables where canonical\nvalues for utilities are set. It contains values which are expected to remain fixed, while\n:ref:`core_eia860__scd_utilities` contains those which may vary from year to year.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.\nAll tables downstream of this one inherit the canonical values established here.",

There is detailed information about what is\nincluded or excluded in each use type for each sector in the footnotes of the EIA's\nonline AEO data browser:\n\nhttps://www.eia.gov/outlooks/aeo/data/browser/#/?id=2-AEO2023\n\nUse caution when aggregating across use types! Energy Use has a tricky system of\nsubtotals, and summing all types within a sector will result in double-counting.\nConsult the EIA's data browser for visibility into which use types are subtotals, and\nwhat they contain: subtotal series are displayed indented, and include all lines\nabove them which are one level out, up to the next indented line. Delivered Energy\nand Total are special cases which include those plus all subtotals above. In this\nway, \"Delivered Energy\" includes purchased electricity, renewable energy, and an\narray of fuels based on sector, and explicitly excludes electricity-related losses.\n\nAEO Energy Use figures are variously referred to as delivered energy, energy\nconsumption, energy use, and energy demand, depending on which use types are\nbeing discussed, and which org and which document is describing them. In PUDL we\nsay energy use or energy consumption.",

The primary keys would have been: plant_id_eia, generator_id, subplant_id and emissions_unit_id_epa, but there are some null records in the generator_id column. ~2 percent of all EPA CAMD records are not successfully mapped to EIA generators.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis table is an augmented version of the core_epa__assn_eia_epacamd\ncrosswalk table which initially comes from the EPA's Github repo camd-eia-crosswalk:\nhttps://github.com/USEPA/camd-eia-crosswalk.\n\nThis table identifies subplants within plant_ids, which are the smallest coherent units\nfor aggregation. A plant_id refers to a legal entity that often contains multiple distinct\npower plants, even of different technology or fuel types.\n\nEPA CEMS data combines information from several parts of a power plant:\n\n* emissions from smokestacks\n* fuel use from combustors\n* electricity production from generators\n\nBut smokestacks, combustors, and generators can be connected in complex, many-to-many\nrelationships. This complexity makes attribution difficult for, as an example,\nallocating pollution to energy producers. Furthermore, heterogeneity within plant_ids\nmake aggregation to the parent entity difficult or inappropriate.\n\nThis table inherits from the EPA's crosswalk, the IDs from EPA CAMD\ncore_epacems__hourly_emissions table itself, the core_eia860__assn_boiler_generator table and the\ncore_eia860__scd_generators table. While the core_epa__assn_eia_epacamd table is the core backbone of the table,\nEPA CAMD IDs ensure there is complete coverage of EPA CAMD reporting units. The EIA 860\ntable addition ensures there is also complete coverage of those units as well.\n\nFor more information about the how this subplant_id is made, see the documentation for\n:func:`pudl.dagster.assets.core.glue.make_subplant_ids` and :func:`pudl.dagster.assets.core.glue.update_subplant_ids`.\n\nBut by analyzing the relationships between combustors and generators,\nas provided in the core_epa__assn_eia_epacamd crosswalk, we can identify distinct power plants.\nThese are the smallest coherent units of aggregation.",

An EPA CEMS\nemissions-unit or smokestack unit is not the same as an EIA unit. See\n:ref:`core_epa__assn_eia_epacamd` for details about how to connect CEMS data to\ncorresponding EIA units.\n\nOnly fossil-combustion units over 25 MW are required to install and use CEMS, so\nthere are some units that do report in EIA-860 or EIA-923 that do not have any\nCEMS data.",

The best approximation for primary keys for this table would be: ``report_year``, ``utility_id_ferc1``, ``plant_name_ferc1``. FERC does not publish plant IDs. The main identifying column is ``plant_name_ferc1`` but that is a free-form string field and there are duplicate records.\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* The ``plant_type`` and ``construction_type`` are standardized into categorical values from free-form strings.\n\n* FERC does not restrict respondents to report unique and non-duplicative plant records. There are sporadic instances of respondents reporting portions of plants and then the total plant (ex: unit 1, unit 2 and total). Use caution when aggregating.\n\n* FERC data is notoriously difficult to extract cleanly, and often contains free-form strings, non-labeled total rows and lack of IDs. See `Notable Irregularities <https://docs.catalyst.coop/pudl/en/latest/data_sources/ferc1.html#notable-irregularities>`_ for details.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nLarge plants have an installed nameplate capacity of more than 10 MW.",

The best approximation for primary keys for this table would be: ``report_year``, ``utility_id_ferc1``, ``plant_name_ferc1``. FERC does not publish plant IDs. The main identifying column is ``plant_name_ferc1`` but that is a free-form string field and there are duplicate records.\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* FERC does not restrict respondents to report unique and non-duplicative plant records. There are sporadic instances of respondents reporting portions of plants and then the total plant (ex: unit 1, unit 2 and total). Use caution when aggregating.\n\n* FERC data is notoriously difficult to extract cleanly, and often contains free-form strings, non-labeled total rows and lack of IDs. See `Notable Irregularities <https://docs.catalyst.coop/pudl/en/latest/data_sources/ferc1.html#notable-irregularities>`_ for details.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nAs reported in Schedule 408 of FERC Form 1.",

This includes how much electricity was purchased, how much it cost, and who it was purchased from. Unfortunately the field describing which other utility the power was being bought from (``seller_name``) is poorly standardized, making it difficult to correlate with other data.\n\nPurchased Power is considered FERC Account 555 according to FERC's Uniform System of Accounts. Reported on pages 326-327 of FERC Form 1.",

      "description": "Annual time series of utilities' electric sales from all rate schedules in effect throughout the year.\n\n\nMost-recent data:\n  2024\n\n\nProcessing:\n  Data has been cleaned and organized into well-modeled tables that serve as building blocks for downstream wide tables and analyses.\n\nSource:\n  FERC Form 1 -- Annual Report of Major Electric Utilities (Schedule 304)\n\nPrimary key:\n  This table has no primary key.\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Some columns contain subtotals; use caution when choosing columns to aggregate.\n\n* Values in rate_schedule_description are free-form strings.\n\n* Data prior to 2021 does not include information in columns: rate_schedule_type and billing_status.\n\n* Units of revenue_per_kwh are suspected to include a mix of dollars and possibly cents.\n\n* FERC data is notoriously difficult to extract cleanly, and often contains free-form strings, non-labeled total rows and lack of IDs. See `Notable Irregularities <https://docs.catalyst.coop/pudl/en/latest/data_sources/ferc1.html#notable-irregularities>`_ for details.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThe pre-2021 data in this table (extracted from FoxProDB vs. XBRL) is\nextremely unstructured. Where the post-2020 data (from XBRL) sorts the data\ninto rate schedule types: residential, industrial, commercial,\npublic_lighting, public_authorities, railroads, interdepartmental,\nprovision_for_rate_refund, commercial_and_industrial, total, and billing\nstatus: billed, unbilled, total, the pre-2021 data stuffs all of that\ninformation (if you're lucky) into the rate_schedule_description column.\nThere's no point trying to parse through the pre 2021\nrate_schedule_description column en masse because it's just too messy. The\ncontents of rate_schedule_description often contain numbers and acronyms\nthat have little to no meaning out of context. The table is structured\nsomewhat like the FERC1 small generators table with headings about rate\nstructure type also embedded into the rate_schedule_description column. To\nall who dare, beware.\n\nThis table is a combination of one pre-2021 (DBF) table and nine post-2020\n(XBRL) tables--one for each rate schedule type plus totals--hence increase\nin data clarity post-2020. The rate_schedule_type and billing_status\ncolumns are only relevant for post-2020 data as they can be reliably parsed\nfrom each of the tables and incorporated into columns. The\nrate_schedule_description is supposed to contain sub-rate_schedule_type\nnames for charges (Ex: Residential 1, Residential 2, etc.). However, the\npre-2021 data contains a little bit of everything (or nothing) and the\npost-2020 has some totals or wonky data thrown in. That's to say, even when\nworking with post-2020 data, be wary of aggregating the data. That's what\nthe \"total\" rows are for.\n\nThe values that come from from the totals table are marked with the string\n\"total\" in the rate_schedule_description column. The totals table is a\nproduct of the transition to XBRL, so these distinguishable totals are only\navailable for data post-2020 (otherwise you could try keyword searching for\n\"total\" in rate_schedule_description). The total table contains two types of\ntotals, the utility totals across all rate schedules in a given year\n(marked with rate_schedule_description = \"total\" and rate_schedule_type =\n\"total\") and each of the utility's individual rate schedule totals in a\ngiven year (marked with rate_schedule_description = \"total\" and\nrate_schedule_type = \"residential\" or any other rate schedule type).\n\nThe rate schedule based XBRL tables only report billed values whereas the\ntotal tables report billed, unbilled, and total values. (See the column\ndescription for more info on the difference between billed and unbilled).\nThis is important to consider if you're endeavoring to compare the subtotal\nvalues with the total values. We have not attempted to fix or verify any\nsubtotals or totals that don't add up.\n\nAnother important note is the possibility of unit discrepancies in certain\ncolumns. The revenue_per_kwh column does not specify reporting units, and\ncloser inspection of the data reveals two clear peaks approximate two orders\nof magnitude apart. This indicates that values may be reported in both\ndollars and cents. However, because the price of energy per kwh varies\nso much regionally, we cannot guarantee which is which and have not put\nany cleaning mechanisms in place to account for this.",

      "description": "Annual time series of plant statistics for internal combustion plants, gas turbine-plants, conventional hydro plants, and pumped storage plants with less than 10 MW installed nameplate capacity and steam plants with less than 25 MW installed nameplate capacity.\n\n\nMost-recent data:\n  2024\n\n\nProcessing:\n  Data has been cleaned and organized into well-modeled tables that serve as building blocks for downstream wide tables and analyses.\n\nSource:\n  FERC Form 1 -- Annual Report of Major Electric Utilities (Schedule 410)\n\nPrimary key:\n  This table has no primary key. The best approximation for primary keys for this table would be: ``report_year``, ``utility_id_ferc1``, ``plant_name_ferc1``. FERC does not publish plant IDs. The main identifying column is ``plant_name_ferc1`` but that is a free-form string field and there are duplicate records.\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* FERC does not restrict respondents to report unique and non-duplicative plant records. There are sporadic instances of respondents reporting portions of plants and then the total plant (ex: unit 1, unit 2 and total). Use caution when aggregating.\n\n* FERC data is notoriously difficult to extract cleanly, and often contains free-form strings, non-labeled total rows and lack of IDs. See `Notable Irregularities <https://docs.catalyst.coop/pudl/en/latest/data_sources/ferc1.html#notable-irregularities>`_ for details.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nAs reported on FERC Form 1 Schedule 410 (pages 410-411)\nand extracted from the FERC Visual FoxPro and XBRL. See our\n``pudl.extract.ferc1.TABLE_NAME_MAP_FERC1`` for links to the raw tables.\n\nThe raw version of this table is more like a digitized PDF than an actual data table.\nThe rows contain lots of information in addition to what the columns might suggest.\nFor instance, a single column may contain header rows, note rows, and total rows. This\nextraneous information is useful, but it prevents proper analysis when mixed in with the\nrest of the values data in the column. We employ a couple of data transformations to\nextract these rows from the data and preserve some of the information they contain\n(fuel type, plant type, FERC license, or general notes about the plant) in separate\ncolumns.",

There are sporadic instances of respondents reporting portions of plants and then the total plant (ex: unit 1, unit 2 and total). Use caution when aggregating.\n\n* FERC data is notoriously difficult to extract cleanly, and often contains free-form strings, non-labeled total rows and lack of IDs.

Each record of this table is supposed to represent one stretch of a transmission line, but there are no IDs and many nulls in the fields which would nominally distinguish unique transmission lines.\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Contains columns which may appear categorical, but are actually free text.\n\n* Some columns contain subtotals; use caution when choosing columns to aggregate.\n\n* FERC data is notoriously difficult to extract cleanly, and often contains free-form strings, non-labeled total rows and lack of IDs. See `Notable Irregularities <https://docs.catalyst.coop/pudl/en/latest/data_sources/ferc1.html#notable-irregularities>`_ for details.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nInformation describing transmission lines, the cost of lines, annual operating and capital expenses, etc. This table includes transmission lines having nominal voltage of 132 kilovolts or greater. Transmission lines below these voltages are required to be reported in group totals only for each voltage.",

See below for additional details.\n\n* FERC data is notoriously difficult to extract cleanly, and often contains free-form strings, non-labeled total rows and lack of IDs. See `Notable Irregularities <https://docs.catalyst.coop/pudl/en/latest/data_sources/ferc1.html#notable-irregularities>`_ for details.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis table includes data from the pre-2021 CSV raw source as well as the newer 2021 through present XBRL raw source.\n\nThis table includes three respondent ID columns: one from the CSV raw source, one from the XBRL raw source and another that is PUDL-derived that links those two source ID's together. This table has filled in source IDs for all records so you can select the full timeseries for a given respondent from any of these three IDs.\n\nAn important caveat to note is that there was some cleaning done to the datetime_utc timestamps. The Form 714 includes sparse documentation for respondents for how to interpret timestamps - the form asks respondents to provide 24 instances of hourly demand for each day. The form is labeled with hour 1-24. There is no indication if hour 1 begins at midnight.\n\nThe XBRL data contained several formats of timestamps. Most records corresponding to hour 1 of the Form have a timestamp with hour 1 as T1. About two thirds of the records in the hour 24 location of the form have a timestamp with an hour reported as T24 while the remaining third report this as T00 of the next day. T24 is not a valid format for the hour of a datetime, so we convert these T24 hours into T00 of the next day. A smaller subset of the respondents reports the 24th hour as the last second of the day - we also convert these records to the T00 of the next day.",

Profiles are stated as a capacity factor (a fraction of nameplate capacity). There are 3 different levels of processing or aggregation provided, all at hourly resolution: Individual plant (wind) or generator (solar) output, capacity-weighted averages of wind and solar output aggregated to the level of balancing authority territories (or transmission zones for larger balancing authorities), and that same aggregated output but with some problematic individual generator profiles modified such that they match the overall production curve of the balancing authority they are within. This data also contains some daily weather data from several sites across the western US and tables describing the way in which individual wind and solar projects were aggregated up to the level of balancing authority or transmission zone.",

It contains values which are expected to remain fixed over time.RUS reports many attributes in many different tables\nacross throughout RUS-7 and RUS-12. In order to compile tidy, well-normalized database\ntables, PUDL collects all instances of these values and and chooses a canonical value.\nBy default, PUDL chooses the most consistently reported value of a given attribute as\nlong as it is at least 70% of the given instances reported. For the ``borrower_name_rus``\nPUDL chooses the most consistently reported value regardless of if it meets this 70%\nthreshold so that all borrowers will have a name. We chose this because most name\nchanges were insignificant (eg. \"and\" changed to \"&\" or \"coop\" changed to \"cooperative\").\nAll tables downstream of this one inherit the canonical values established\nhere..\n\nThis table contains all of the Active Distribution Borrowers as of each report year who were eligible to report to RUS Form 12.  If these Borrowers have reported to RUS they will have records in the enclosed data tables, however a small number of these Borrowers did not report for various reasons and these Borrowers will not be represented in any of the other tables.",

This table has no primary key because there is one plant (Walter Scott) that has duplicate records every year. Based on other RUS-12 tables, it is likely that these duplicate records are the borrowers' ownership portion of the plant as well as the total plant but there is no clear indication in this table.\n\nThe primary key of this table otherwise would be: ['report_date', 'borrower_id_rus', 'plant_name_rus', 'cost_group', 'cost_type'].\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Some columns contain subtotals; use caution when choosing columns to aggregate.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThe cost column in this table is expected to be largely non-null, the cost_per_mwh and cost_per_mmbtu columns only apply to some cost_type's and even plant_type's and thus are expected to contain many nulls.",

The primary key for this table would be report_date, borrower_id_rus, plant_name_rus, and plant_type but the plant_type column is not reported before 2009 causing lots of duplicate records. Because none of the other fields are static year-over-year, there is no reliable way to backfill the plant_type column in instances where there are different plant_types reported for the same plant in later years.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThe plant_type field was only included in the data starting in 2009. We backfill records with only one reported plant_type per borrower/plant name/year. Records with multiple plant_types per borrower/plant name/year are left with null plant_type because there is no reliable way to determine which plant_type is associated with which record back in time. Plants who's names are reported differently pre and post 2009 will also miss being backfilled.",

      "description": "Annual time series of labor and payroll information for plants owned by RUS borrowers.\n\n\nMost-recent data:\n  2021\n\n\nProcessing:\n  Data has been cleaned and organized into well-modeled tables that serve as building blocks for downstream wide tables and analyses.\n\nSource:\n  USDA RUS Form 12 -- Financial and Operating Report: Electric Power Supply (Parts D, E, F, G - Section B)\n\nPrimary key:\n  This table has no primary key. The primary key should be report_date, borrower_id_rus, plant_name_rus, and plant_type, but this table did not report plant_type before 2009 and there are respondents who report multiple rows per plant pre-2009. The data cannot be backfilled because there is no way to distinguish between duplicate rows pre-2009.\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Some columns contain subtotals; use caution when choosing columns to aggregate.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nNote the lack of plant_type pre-2009 leading to a lack of reliable primary keys.\n\nPlant-level data from :ref:`core_rus12__yearly_plant_operations_by_plant` can be matched to data from this table, but you must also join this data usingthe ``borrower_id_rus`` column as well as the ``report_date`` and ``plant_name``. This is because the :ref:`core_rus12__yearly_plant_operations_by_plant` table includes records from each plant owner. The RUS instructions note that:\n\nyou should use caution when using total plant data since there are cases where more than one Borrower shares units at the same plant which means that you will be getting duplicate plant total records (and there is no guarantee that the total plant records entered by two borrowers for the same plant will be identical).",

This table has no primary key because there are a handful of plants that have duplicate records. The primary key of this table otherwise would be: [`report_date`, `borrower_id_rus`, `plant_name_rus`, `plant_name_rus`, `unit_id_rus`, `plant_type`, `is_full_ownership_portion`, `is_partly_owned_by_borrower`].\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThe data in this table comes from five different portions of RUS 12 corresponding to different plant types (steam, hydroelectric, combined_cycle, internal_combustion and nuclear).\nThe original form includes plant operations data for each plant type reported in multiple ways: with records corresponding to the portion of plants that borrowers own as well as the whole plant. We split these records into two tables, :ref:`core_rus12__yearly_plant_operations_by_borrower`, which contains records reported at the borrower level, and  :ref:`core_rus12__yearly_plant_operations_by_plant`, which contains records reported at the plant level.Records that are wholly owned by one borrower show up in both :ref:`core_rus12__yearly_plant_operations_by_borrower` and :ref:`core_rus12__yearly_plant_operations_by_plant`.\n\nThere are two boolean columns used to delineate which records are associated with the borrowers' share vs the whole plant - which is documented in ``_OR_PowerSupply Plant File Documentation.rtf`` in the newer years in the RUS 12 archive. One of these two fields - ``is_partly_owned_by_borrower`` - was not reported before 2009. For the pre-2009 years, we assume that all records that report TRUE for is_full_ownership_portion should end up in the by-plant table while all records should end up in the by-borrower portion of the table.Like the post-2009 records, this involves records from the original tables ending up in both of these PUDL tables.\n\nAlso there are two cleaning steps that we performed that alter the original data slightly:\n\n* **One dropped with unexpected ownership label and duplicate data**: There is a   Wisdom steam plant record that is labeled to be both fully owned by borrower   and partly owned for one year, which is an unexpected combo based on the   `_OR_PowerSupply Plant File Documentation.rst` documentation file in the rus12   archive. Luckily this plant has exactly the same records as the other Wisdom steam  plant that year with more expected ownership labels.* **Replaced two string values for unit_id_rus**: There are two instances from 2018   of unit_id_rus's that have string values in them - ``WSL GT 12`` and ``WSL ST 10``.   Based on pre-cleaned data, we were able to clearly identify that we can use just   the numeric values in these bad strings - 12 and 10 respectively. This enables us   to have an integer type for this unit_id_rus column.",

      "description": "Annual time series of whole plant operational data including fuel consumption and operational hours.\n\n\nMost-recent data:\n  2021\n\n\nProcessing:\n  Data has been cleaned and organized into well-modeled tables that serve as building blocks for downstream wide tables and analyses.\n\nSource:\n  USDA RUS Form 12 -- Financial and Operating Report: Electric Power Supply (Part D, E, F (CC), F (IC) & G - Section A)\n\nPrimary key:\n  This table has no primary key. This table has no primary key because there are a handful of plants that have duplicate records. The primary key of this table otherwise would be: [`report_date`, `borrower_id_rus`, `plant_name_rus`, `plant_name_rus`, `unit_id_rus`, `plant_type`, `is_full_ownership_portion`, `is_partly_owned_by_borrower`].\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThe data in this table comes from five different portions of RUS 12 corresponding to different plant types (steam, hydroelectric, combined_cycle, internal_combustion and nuclear).\nThe original form includes plant operations data for each plant type reported in multiple ways: with records corresponding to the portion of plants that borrowers own as well as the whole plant. We split these records into two tables, :ref:`core_rus12__yearly_plant_operations_by_borrower`, which contains records reported at the borrower level, and  :ref:`core_rus12__yearly_plant_operations_by_plant`, which contains records reported at the plant level.Records that are wholly owned by one borrower show up in both :ref:`core_rus12__yearly_plant_operations_by_borrower` and :ref:`core_rus12__yearly_plant_operations_by_plant`.\n\nThere are two boolean columns used to delineate which records are associated with the borrowers' share vs the whole plant - which is documented in ``_OR_PowerSupply Plant File Documentation.rtf`` in the newer years in the RUS 12 archive. One of these two fields - ``is_partly_owned_by_borrower`` - was not reported before 2009. For the pre-2009 years, we assume that all records that report TRUE for is_full_ownership_portion should end up in the by-plant table while all records should end up in the by-borrower portion of the table.Like the post-2009 records, this involves records from the original tables ending up in both of these PUDL tables.\n\nAlso there are two cleaning steps that we performed that alter the original data slightly:\n\n* **One dropped with unexpected ownership label and duplicate data**: There is a   Wisdom steam plant record that is labeled to be both fully owned by borrower   and partly owned for one year, which is an unexpected combo based on the   `_OR_PowerSupply Plant File Documentation.rst` documentation file in the rus12   archive. Luckily this plant has exactly the same records as the other Wisdom steam  plant that year with more expected ownership labels.* **Replaced two string values for unit_id_rus**: There are two instances from 2018   of unit_id_rus's that have string values in them - ``WSL GT 12`` and ``WSL ST 10``.   Based on pre-cleaned data, we were able to clearly identify that we can use just   the numeric values in these bad strings - 12 and 10 respectively. This enables us   to have an integer type for this unit_id_rus column..\n\nPlant-level data can be matched to the :ref:core_rus12__yearly_plant_labor` and forthcoming core_rus12__yearly_plant_factors_and_maximum_demand, which report Section B and C data for all plants. The RUS instructions note that:\n\nyou should use caution when using total plant data since there are cases where more than one Borrower shares units at the same plant which means that you will be getting duplicate plant total records (and there is no guarantee that the total plant records entered by two borrowers for the same plant will be identical).",

It contains values which are expected to remain fixed over time.RUS reports many attributes in many different tables\nacross throughout RUS-7 and RUS-12. In order to compile tidy, well-normalized database\ntables, PUDL collects all instances of these values and and chooses a canonical value.\nBy default, PUDL chooses the most consistently reported value of a given attribute as\nlong as it is at least 70% of the given instances reported. For the ``borrower_name_rus``\nPUDL chooses the most consistently reported value regardless of if it meets this 70%\nthreshold so that all borrowers will have a name. We chose this because most name\nchanges were insignificant (eg. \"and\" changed to \"&\" or \"coop\" changed to \"cooperative\").\nAll tables downstream of this one inherit the canonical values established\nhere..\n\nThis table contains all of the Active Distribution Borrowers as of each report year who were eligible to report to RUS Form 7.  If these Borrowers have reported to RUS they will have records in the enclosed data tables, however a small number of these Borrowers did not report for various reasons and these Borrowers will not be represented in any of the other tables.",

See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nReports the quantity of each type of fuel consumed by each boiler on a monthly basis, as\nwell as the sulfur and ash content of those fuels. Fuel quantity is reported in standard\nEIA fuel units (tons, barrels, Mcf). Heat content per unit of fuel is also reported,\nmaking this table useful for calculating the thermal efficiency (heat rate) of various\ngeneration units.\n\nThis table provides better coverage of the entire fleet of generators than the\n``core_eia923__monthly_generation_fuel`` table, but the fuel consumption reported here is not directly\nassociated with a generator. This complicates the heat rate calculation, since the\nassociations between individual boilers and generators are incomplete and can be\ncomplex.\n\nThis table inherits canonicalized values for plants and utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

      "description": "Individual fuel deliveries to power plants, organized by fuel type and supplier.\n\n\nMost-recent data:\n  2025\n\n\nProcessing:\n  Data has been expanded into a wide/denormalized format, with IDs and codes accompanied by human-readable names and descriptions.\n\nSource:\n  EIA Form 923 -- Power Plant Operations Report (Schedule 2 - Part A)\n\nPrimary key:\n  This table has no primary key. Each record describes an individual fuel delivery. There can be multiple deliveries of the same type of fuel from the same supplier to the same plant in a single month, so the table has no natural primary key.\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Date column arbitrarily uses the first of the month.\n\n* Some values have been redacted.\n\n* Time of fuel deliveries is not necessarily connected with time of fuel consumption.\n\n* Data has been drawn from several EIA sources which are not always consistent with each other, and PUDL chooses the most consistent or relevant value to facilitate cross-referencing even if that means some values will differ from the raw sources. See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n* Contains estimated values.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThere can be a significant delay between the receipt of fuel and its consumption, so\nusing this table to infer monthly attributes associated with power generation may not be\nentirely accurate. However, this is the most granular data we have describing fuel\ncosts, and we use it in calculating the marginal cost of electricity for individual\ngeneration units.\n\nUnder some circumstances utilities are allowed to treat the price of fuel as proprietary\nbusiness data, meaning it is redacted from the publicly available spreadsheets. It's\nstill reported to EIA and influences the aggregated (state, region, annual, etc.) fuel\nprices they publish. From 2009-2021 about 1/3 of all prices are redacted. The missing\ndata is not randomly distributed. Deregulated markets dominated by merchant generators\n(independent power producers) redact much more data, and natural gas is by far the most\nlikely fuel to have its price redacted. This means, for instance, that the entire\nNortheastern US reports essentially no fine-grained data about its natural gas prices.\n\nAdditional data which we haven't yet integrated is available in a similar format from\n2002-2008 via the EIA-423, and going back as far as 1972 from the FERC-423.\n\nThis table inherits canonicalized values for plants and utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis is the most granular information we have about how much electricity individual\ngenerators are producing, but only about half of all the generation reported in the\n``core_eia923__monthly_generation_fuel`` appears in this table due to the different reporting\nrequirements imposed on different types and sizes of generators.\n\nWhenever possible, we use this generator-level net generation to estimate the heat rates\nof generation units and the marginal cost of electricity on a per-generator basis, but\nthose calculations depend on plant-level fuel costs and sometimes uncertain or\nincomplete boiler-generator associations.\n\nThis table inherits canonicalized values for plants and utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nDenormalized, combined data from the ``core_eia923__monthly_generation_fuel`` and\n``core_eia923__monthly_generation_fuel_nuclear`` with nuclear generation aggregated from the nuclear\ngeneration unit level up to the plant prime mover level, so as to be compatible with\nfossil fuel generation data.\n\nThis data can't be easily linked to individual boilers, generators, and\ngeneration units, but it is provides the most complete coverage\nof fuel consumption and electricity generation for the entire generation fleet. We use\nthe primary fuels and prime movers reported for each generator along with their\ncapacities to attribute fuel consumption and generation when it isn't directly reported\nin the ``core_eia923__monthly_generation`` and ``core_eia923__monthly_boiler_fuel`` tables in order to calculate\ncapacity factors, heat rates, and the marginal cost of electricity.\n\nThe table makes a distinction between all fuel consumed and fuel consumed for\nelectricity generation because some units are also combined heat and power (CHP) units,\nand also provide high temperature process heat at the expense of net electricity\ngeneration.\n\n\nThis table inherits canonicalized values for plants and utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nReports the quantity of each type of fuel consumed by each boiler on a monthly basis, as\nwell as the sulfur and ash content of those fuels. Fuel quantity is reported in standard\nEIA fuel units (tons, barrels, Mcf). Heat content per unit of fuel is also reported,\nmaking this table useful for calculating the thermal efficiency (heat rate) of various\ngeneration units.\n\nThis table provides better coverage of the entire fleet of generators than the\n``core_eia923__monthly_generation_fuel`` table, but the fuel consumption reported here is not directly\nassociated with a generator. This complicates the heat rate calculation, since the\nassociations between individual boilers and generators are incomplete and can be\ncomplex.\n\nThis table inherits canonicalized values for plants and utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis table is an aggregation of the more detailed data in the\n:ref:`core_eia923__fuel_receipts_costs` table. It provides a tidy timeseries\nof deliveries by fuel type for each plant. However, not all values in the\noriginal table can be aggregated meaningfully, so this table contains only a\nsubset of the source table columns -- primarily numerical values and a\nhandful of categorical variables, plus additional attributes that are\nconstant within each plant-fuel-time period grouping and associated with the\nplant or utility. When aggregating numerical values any sum that contains an\nNA value is treated as NA.\n\nThis table inherits canonicalized values for plants and utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis is the most granular information we have about how much electricity individual\ngenerators are producing, but only about half of all the generation reported in the\n``core_eia923__monthly_generation_fuel`` appears in this table due to the different reporting\nrequirements imposed on different types and sizes of generators.\n\nWhenever possible, we use this generator-level net generation to estimate the heat rates\nof generation units and the marginal cost of electricity on a per-generator basis, but\nthose calculations depend on plant-level fuel costs and sometimes uncertain or\nincomplete boiler-generator associations.\n\nThis table inherits canonicalized values for plants and utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

      "description": "Monthly time series of of estimated net generation and fuel consumption by generator.\n\n\nMost-recent data:\n  2024\n\n\nProcessing:\n  Data has been expanded into a wide/denormalized format, with IDs and codes accompanied by human-readable names and descriptions.\n\nSource:\n  EIA Form 923 -- Power Plant Operations Report (Schedule 3)\n\nPrimary key:\n  report_date, plant_id_eia, generator_id\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Contains estimated values.\n\n* This downscaling process used to create this table does not distinguish between primary and secondary energy_sources for generators (see below for implications).\n\n* Date column arbitrarily uses the first of the month.\n\n* A small number of respondents only report annual fuel consumption, and all of it is reported in December.\n\n* Data has been drawn from several EIA sources which are not always consistent with each other, and PUDL chooses the most consistent or relevant value to facilitate cross-referencing even if that means some values will differ from the raw sources. See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n* Contains information from multiple raw inputs.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nBased on allocating net electricity generation and fuel consumption reported in the EIA-923 generation and generation_fuel tables to individual generators.\n\nThe net generation and fuel consumption allocation\nmethod PUDL employs begins with the following context of the originally reported\nEIA-860 and EIA-923 data:\n\n* The :ref:`core_eia923__monthly_generation_fuel` table is the authoritative source of\n  information about how much generation and fuel consumption is attributable to an\n  entire plant. This table has the most complete data coverage, but it is not the most\n  granular data reported.\n* The :ref:`core_eia923__monthly_generation` table contains the most granular net\n  generation data. It is reported at the ``plant_id_eia``, ``generator_id`` and\n  ``report_date`` level. This table includes only ~40% of the total MWhs reported in\n  the :ref:`core_eia923__monthly_generation_fuel` table.\n* The :ref:`core_eia923__monthly_boiler_fuel` table contains the most granular fuel\n  consumption data.  It is reported at the boiler/prime mover/energy source level. This\n  table includes only ~40% of the total MMBTUs reported in the\n  :ref:`core_eia923__monthly_generation_fuel` table.\n* The :ref:`core_eia860__scd_generators` table provides an exhaustive list of all\n  generators whose generation is being reported in the\n  :ref:`core_eia923__monthly_generation_fuel` table.\n\n\n\nIn this table, PUDL aggregates the net generation and fuel consumption that has been allocated to the ``generator_id``/``energy_source_code``/``prime_mover_code`` level in the:ref:`out_eia923__monthly_generation_fuel_by_generator_energy_source` to the generator level.This process does not distinguish between primary and secondary energy_sources for generators. Net generation is allocated equally between energy source codes, so if a plant has multiple generators with the same prime_mover_code but different energy source codes the core_eia923__monthly_generation_fuel records will be associated similarly between these two generators. Allocated net generation will still be proportional to each generator's net generation or capacity.\n\nThis table inherits canonicalized values for generators, plants, and utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

This table has the most complete data coverage, but it is not the most\n  granular data reported.\n* The :ref:`core_eia923__monthly_generation` table contains the most granular net\n  generation data. It is reported at the ``plant_id_eia``, ``generator_id`` and\n  ``report_date`` level. This table includes only ~40% of the total MWhs reported in\n  the :ref:`core_eia923__monthly_generation_fuel` table.\n* The :ref:`core_eia923__monthly_boiler_fuel` table contains the most granular fuel\n  consumption data.  It is reported at the boiler/prime mover/energy source level. This\n  table includes only ~40% of the total MMBTUs reported in the\n  :ref:`core_eia923__monthly_generation_fuel` table.\n* The :ref:`core_eia860__scd_generators` table provides an exhaustive list of all\n  generators whose generation is being reported in the\n  :ref:`core_eia923__monthly_generation_fuel` table.\n\n\n\nIn this table, PUDL has allocated the net electricity generation and fuel consumption from :ref:`core_eia923__monthly_generation_fuel` to the ``generator_id``/``energy_source_code``/``prime_mover_code`` level.\n\nThe allocation process entails generating a fraction for each record based on the net generation in the :ref:`core_eia923__monthly_generation` table and the capacity from the :ref:`core_eia860__scd_generators` table. This process does not distinguish between primary and secondary energy_sources for generators. Net generation is allocated equally between energy source codes, so if a plant has multiple generators with the same prime_mover_code but different energy source codes the core_eia923__monthly_generation_fuel records will be associated similarly between these two generators. Allocated net generation will still be proportional to each generator's net generation or capacity.",

See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nDenormalized, combined data from the ``core_eia923__monthly_generation_fuel`` and\n``core_eia923__monthly_generation_fuel_nuclear`` with nuclear generation aggregated from the nuclear\ngeneration unit level up to the plant prime mover level, so as to be compatible with\nfossil fuel generation data.\n\nThis data can't be easily linked to individual boilers, generators, and\ngeneration units, but it is provides the most complete coverage\nof fuel consumption and electricity generation for the entire generation fleet. We use\nthe primary fuels and prime movers reported for each generator along with their\ncapacities to attribute fuel consumption and generation when it isn't directly reported\nin the ``core_eia923__monthly_generation`` and ``core_eia923__monthly_boiler_fuel`` tables in order to calculate\ncapacity factors, heat rates, and the marginal cost of electricity.\n\nThe table makes a distinction between all fuel consumed and fuel consumed for\nelectricity generation because some units are also combined heat and power (CHP) units,\nand also provide high temperature process heat at the expense of net electricity\ngeneration.\n\n\nThis table inherits canonicalized values for plants and utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nReports the quantity of each type of fuel consumed by each boiler on a monthly basis, as\nwell as the sulfur and ash content of those fuels. Fuel quantity is reported in standard\nEIA fuel units (tons, barrels, Mcf). Heat content per unit of fuel is also reported,\nmaking this table useful for calculating the thermal efficiency (heat rate) of various\ngeneration units.\n\nThis table provides better coverage of the entire fleet of generators than the\n``core_eia923__monthly_generation_fuel`` table, but the fuel consumption reported here is not directly\nassociated with a generator. This complicates the heat rate calculation, since the\nassociations between individual boilers and generators are incomplete and can be\ncomplex.\n\nThis table inherits canonicalized values for plants and utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis table is an aggregation of the more detailed data in the\n:ref:`core_eia923__fuel_receipts_costs` table. It provides a tidy timeseries\nof deliveries by fuel type for each plant. However, not all values in the\noriginal table can be aggregated meaningfully, so this table contains only a\nsubset of the source table columns -- primarily numerical values and a\nhandful of categorical variables, plus additional attributes that are\nconstant within each plant-fuel-time period grouping and associated with the\nplant or utility. When aggregating numerical values any sum that contains an\nNA value is treated as NA.\n\nThis table inherits canonicalized values for plants and utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis is the most granular information we have about how much electricity individual\ngenerators are producing, but only about half of all the generation reported in the\n``core_eia923__monthly_generation_fuel`` appears in this table due to the different reporting\nrequirements imposed on different types and sizes of generators.\n\nWhenever possible, we use this generator-level net generation to estimate the heat rates\nof generation units and the marginal cost of electricity on a per-generator basis, but\nthose calculations depend on plant-level fuel costs and sometimes uncertain or\nincomplete boiler-generator associations.\n\nThis table inherits canonicalized values for plants and utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

      "description": "Annual time series of of estimated net generation and fuel consumption by generator.\n\n\nMost-recent data:\n  2024\n\n\nProcessing:\n  Data has been expanded into a wide/denormalized format, with IDs and codes accompanied by human-readable names and descriptions.\n\nSource:\n  EIA Form 923 -- Power Plant Operations Report (Schedule 3)\n\nPrimary key:\n  report_date, plant_id_eia, generator_id\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Contains estimated values.\n\n* This downscaling process used to create this table does not distinguish between primary and secondary energy_sources for generators (see below for implications).\n\n* Date column arbitrarily uses the first of the month.\n\n* A small number of respondents only report annual fuel consumption, and all of it is reported in December.\n\n* Data has been drawn from several EIA sources which are not always consistent with each other, and PUDL chooses the most consistent or relevant value to facilitate cross-referencing even if that means some values will differ from the raw sources. See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n* Contains information from multiple raw inputs.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nBased on allocating net electricity generation and fuel consumption reported in the EIA-923 generation and generation_fuel tables to individual generators.\n\nThe net generation and fuel consumption allocation\nmethod PUDL employs begins with the following context of the originally reported\nEIA-860 and EIA-923 data:\n\n* The :ref:`core_eia923__monthly_generation_fuel` table is the authoritative source of\n  information about how much generation and fuel consumption is attributable to an\n  entire plant. This table has the most complete data coverage, but it is not the most\n  granular data reported.\n* The :ref:`core_eia923__monthly_generation` table contains the most granular net\n  generation data. It is reported at the ``plant_id_eia``, ``generator_id`` and\n  ``report_date`` level. This table includes only ~40% of the total MWhs reported in\n  the :ref:`core_eia923__monthly_generation_fuel` table.\n* The :ref:`core_eia923__monthly_boiler_fuel` table contains the most granular fuel\n  consumption data.  It is reported at the boiler/prime mover/energy source level. This\n  table includes only ~40% of the total MMBTUs reported in the\n  :ref:`core_eia923__monthly_generation_fuel` table.\n* The :ref:`core_eia860__scd_generators` table provides an exhaustive list of all\n  generators whose generation is being reported in the\n  :ref:`core_eia923__monthly_generation_fuel` table.\n\n\n\nIn this table, PUDL aggregates the net generation and fuel consumption that has been allocated to the ``generator_id``/``energy_source_code``/``prime_mover_code`` level in the:ref:`out_eia923__yearly_generation_fuel_by_generator_energy_source` to the generator level.This process does not distinguish between primary and secondary energy_sources for generators. Net generation is allocated equally between energy source codes, so if a plant has multiple generators with the same prime_mover_code but different energy source codes the core_eia923__monthly_generation_fuel records will be associated similarly between these two generators. Allocated net generation will still be proportional to each generator's net generation or capacity.\n\nThis table inherits canonicalized values for generators, plants, and utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

This table has the most complete data coverage, but it is not the most\n  granular data reported.\n* The :ref:`core_eia923__monthly_generation` table contains the most granular net\n  generation data. It is reported at the ``plant_id_eia``, ``generator_id`` and\n  ``report_date`` level. This table includes only ~40% of the total MWhs reported in\n  the :ref:`core_eia923__monthly_generation_fuel` table.\n* The :ref:`core_eia923__monthly_boiler_fuel` table contains the most granular fuel\n  consumption data.  It is reported at the boiler/prime mover/energy source level. This\n  table includes only ~40% of the total MMBTUs reported in the\n  :ref:`core_eia923__monthly_generation_fuel` table.\n* The :ref:`core_eia860__scd_generators` table provides an exhaustive list of all\n  generators whose generation is being reported in the\n  :ref:`core_eia923__monthly_generation_fuel` table.\n\n\n\nIn this table, PUDL has allocated the net electricity generation and fuel consumption from :ref:`core_eia923__monthly_generation_fuel` to the ``generator_id``/``energy_source_code``/``prime_mover_code`` level.\n\nThe allocation process entails generating a fraction for each record based on the net generation in the :ref:`core_eia923__monthly_generation` table and the capacity from the :ref:`core_eia860__scd_generators` table. This process does not distinguish between primary and secondary energy_sources for generators. Net generation is allocated equally between energy source codes, so if a plant has multiple generators with the same prime_mover_code but different energy source codes the core_eia923__monthly_generation_fuel records will be associated similarly between these two generators. Allocated net generation will still be proportional to each generator's net generation or capacity.",

      "description": "Annual time series of of estimated net generation and fuel consumption for each generator, associated with each combination of generator, energy source, prime mover, and owner.\n\n\nMost-recent data:\n  2024\n\n\nProcessing:\n  Data is ready for use in analyses, but for practical reasons has not been denormalized and remains in narrow format.\n\nSource:\n  EIA Form 923 -- Power Plant Operations Report (Schedule 3)\n\nPrimary key:\n  report_date, plant_id_eia, generator_id, prime_mover_code, energy_source_code, utility_id_eia, ownership_record_type\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Contains estimated values.\n\n* This downscaling process used to create this table does not distinguish between primary and secondary energy_sources for generators (see below for implications).\n\n* Date column arbitrarily uses the first of the month.\n\n* Data has been drawn from several EIA sources which are not always consistent with each other, and PUDL chooses the most consistent or relevant value to facilitate cross-referencing even if that means some values will differ from the raw sources. See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n* Contains information from multiple raw inputs.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThe net generation and fuel consumption allocation\nmethod PUDL employs begins with the following context of the originally reported\nEIA-860 and EIA-923 data:\n\n* The :ref:`core_eia923__monthly_generation_fuel` table is the authoritative source of\n  information about how much generation and fuel consumption is attributable to an\n  entire plant. This table has the most complete data coverage, but it is not the most\n  granular data reported.\n* The :ref:`core_eia923__monthly_generation` table contains the most granular net\n  generation data. It is reported at the ``plant_id_eia``, ``generator_id`` and\n  ``report_date`` level. This table includes only ~40% of the total MWhs reported in\n  the :ref:`core_eia923__monthly_generation_fuel` table.\n* The :ref:`core_eia923__monthly_boiler_fuel` table contains the most granular fuel\n  consumption data.  It is reported at the boiler/prime mover/energy source level. This\n  table includes only ~40% of the total MMBTUs reported in the\n  :ref:`core_eia923__monthly_generation_fuel` table.\n* The :ref:`core_eia860__scd_generators` table provides an exhaustive list of all\n  generators whose generation is being reported in the\n  :ref:`core_eia923__monthly_generation_fuel` table.\n\n\n\nIn this table, PUDL has scaled the net electricity generation and fuel consumption from :ref:`core_eia923__monthly_generation_fuel` by ownership from :ref:`out_eia860__yearly_ownership`. Note that the utility_id_eia in this table refers to the OWNER of the generator, not the operator.\n\nThis process does not distinguish between primary and secondary energy_sources for generators. Net generation is allocated equally between energy source codes, so if a plant has multiple generators with the same prime_mover_code but different energy source codes the core_eia923__monthly_generation_fuel records will be associated similarly between these two generators. Allocated net generation will still be proportional to each generator's net generation or capacity.\n\nThis table inherits canonicalized values for generators and plants.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nDenormalized, combined data from the ``core_eia923__monthly_generation_fuel`` and\n``core_eia923__monthly_generation_fuel_nuclear`` with nuclear generation aggregated from the nuclear\ngeneration unit level up to the plant prime mover level, so as to be compatible with\nfossil fuel generation data.\n\nThis data can't be easily linked to individual boilers, generators, and\ngeneration units, but it is provides the most complete coverage\nof fuel consumption and electricity generation for the entire generation fleet. We use\nthe primary fuels and prime movers reported for each generator along with their\ncapacities to attribute fuel consumption and generation when it isn't directly reported\nin the ``core_eia923__monthly_generation`` and ``core_eia923__monthly_boiler_fuel`` tables in order to calculate\ncapacity factors, heat rates, and the marginal cost of electricity.\n\nThe table makes a distinction between all fuel consumed and fuel consumed for\nelectricity generation because some units are also combined heat and power (CHP) units,\nand also provide high temperature process heat at the expense of net electricity\ngeneration.\n\n\nThis table inherits canonicalized values for plants and utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

Expect nulls.\n\n* Data has been drawn from several EIA sources which are not always consistent with each other, and PUDL chooses the most consistent or relevant value to facilitate cross-referencing even if that means some values will differ from the raw sources. See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n* Contains information from multiple raw inputs.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis table includes all monthly attributes\nfor all generators reported to EIA-860 and EIA-923.\n\nTo provide a complete picture of generator data, this table compiles data from many\ndifferent EIA tables, including directly reported, imputed and calculated columns.\nWe suggest using this table if you want to explore monthly attributes about generators\nand would rather use a more complete and denormalized table. If you are more interested\nin the originally reported values, we recommend searching for core_eia with the column\nyou are most interested in.\n\nThe calculations of capacity factor, heat rate, fuel cost per MMBTU and fuel cost per MWh\nare based on the allocation of net generation reported on the basis of plant, prime mover\nand energy source to individual generators - which comes from this table:\n:ref:`out_eia923__monthly_generation_fuel_by_generator`.\n\nHeat rates by generator-monthly are estimated by using\nallocated estimates for per-generator net generation and fuel consumption as well as the\n:ref:`core_eia923__monthly_boiler_fuel` table, which reports fuel consumed by boiler.\nHeat rates are necessary to estimate the amount of fuel consumed by a generation unit,\nand thus the fuel cost per MWh generated.\n\nPlant specific fuel prices are taken from the\n:ref:`core_eia923__fuel_receipts_costs` table, which only has ~70% coverage,\nleading to some generators with heat rate estimates still lacking fuel cost\nestimates.\n\nThis table inherits canonicalized values for generators, plants, and utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

The plant part records have a one to many relationship\nto the associated 'plant_gen' records. The 'plant_gen' records are also included in\nthe plant part records, so for these records there is a one to one relationship and\nthe ``record_id_eia`` and the ``record_id_eia_plant_gen`` are the same.\n\nAll of the columns in this table that have a suffix of '_plant_gen' are attributes of\nthe ``record_id_eia_plant_gen`` record.",

      "description": "Annual time series of all EIA boiler attributes.\n\n\nMost-recent data:\n  2025\n\n\nProcessing:\n  Data has been expanded into a wide/denormalized format, with IDs and codes accompanied by human-readable names and descriptions.\n\nSource:\n  EIA -- Mix of multiple EIA Forms\n\nPrimary key:\n  plant_id_eia, boiler_id, report_date\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Data has been drawn from several EIA sources which are not always consistent with each other, and PUDL chooses the most consistent or relevant value to facilitate cross-referencing even if that means some values will differ from the raw sources. See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n* Contains information from multiple raw inputs.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis table inherits canonicalized values for boilers, plants, and utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

      "description": "Annual time series of all generator attributes including calculated capacity factor, heat rate, fuel cost per MMBTU and fuel cost per MWh.\n\n\nMost-recent data:\n  2026\n\n\nProcessing:\n  Data has been expanded into a wide/denormalized format, with IDs and codes accompanied by human-readable names and descriptions.\n\nSource:\n  EIA -- Mix of multiple EIA Forms\n\nPrimary key:\n  report_date, plant_id_eia, generator_id\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Contains estimated values.\n\n* Due to coverage problems in other tables, some generators have heat rate estimates but not fuel cost estimates.\n\n* Not all columns are originally reported in or calculable from the input tables. Expect nulls.\n\n* Data has been drawn from several EIA sources which are not always consistent with each other, and PUDL chooses the most consistent or relevant value to facilitate cross-referencing even if that means some values will differ from the raw sources. See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n* Contains information from multiple raw inputs.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis table includes all yearly attributes\nfor all generators reported to EIA-860 and EIA-923.\n\nTo provide a complete picture of generator data, this table compiles data from many\ndifferent EIA tables, including directly reported, imputed and calculated columns.\nWe suggest using this table if you want to explore yearly attributes about generators\nand would rather use a more complete and denormalized table. If you are more interested\nin the originally reported values, we recommend searching for core_eia with the column\nyou are most interested in.\n\nThe calculations of capacity factor, heat rate, fuel cost per MMBTU and fuel cost per MWh\nare based on the allocation of net generation reported on the basis of plant, prime mover\nand energy source to individual generators - which comes from this table:\n:ref:`out_eia923__yearly_generation_fuel_by_generator`.\n\nHeat rates by generator-yearly are estimated by using\nallocated estimates for per-generator net generation and fuel consumption as well as the\n:ref:`core_eia923__monthly_boiler_fuel` table, which reports fuel consumed by boiler.\nHeat rates are necessary to estimate the amount of fuel consumed by a generation unit,\nand thus the fuel cost per MWh generated.\n\nPlant specific fuel prices are taken from the\n:ref:`core_eia923__fuel_receipts_costs` table, which only has ~70% coverage,\nleading to some generators with heat rate estimates still lacking fuel cost\nestimates.\n\nThis table inherits canonicalized values for generators, plants, and utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

This table would have a primary key of the following columns, except there are ~200 records without utility IDs: ['plant_id_eia', 'generator_id', 'report_date', 'utility_id_eia', 'ownership_record_type'].\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Some columns contain subtotals; use caution when choosing columns to aggregate.\n\n* Data has been drawn from several EIA sources which are not always consistent with each other, and PUDL chooses the most consistent or relevant value to facilitate cross-referencing even if that means some values will differ from the raw sources. See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n* Contains information from multiple raw inputs.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nGenerators that report to EIA can have\nmultiple utility owners. EIA reports the ownership fraction for each of the owners\nof generators (see :ref:`core_eia860__scd_ownership`). This table includes two records\nfor each generator's owner: one record represents a total ownership stake and the\nother record represents a proportional ownership stake (the ``ownership_record_type``\ncolumn labeled as \"total\" and \"owned\" respectively). All of the values reported for\nthese generator-owner records are scaled to the ownership stake (represented by\n``fraction_owned``).\n\nThis table was created to represent every possible version of ownership slices of the\nEIA generators. It is primarily used as an input to :ref:`out_eia__yearly_plant_parts`.\n\nThis table inherits canonicalized values for generators, plants, and utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

      "description": "Annual time series of all EIA plant parts, for use in matching to FERC 1.\n\n\nMost-recent data:\n  2026\n\n\nProcessing:\n  Data has been expanded into a wide/denormalized format, with IDs and codes accompanied by human-readable names and descriptions.\n\nSource:\n  EIA -- Mix of multiple EIA Forms\n\nPrimary key:\n  record_id_eia\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Some columns contain subtotals; use caution when choosing columns to aggregate.\n\n* Data has been drawn from several EIA sources which are not always consistent with each other, and PUDL chooses the most consistent or relevant value to facilitate cross-referencing even if that means some values will differ from the raw sources. See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n* Contains information from multiple raw inputs.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nPractically speaking, a plant is a collection of generator(s). There\nare many attributes of generators (i.e. prime mover, primary fuel source, technology\ntype). We can use these generator attributes to group generator records into larger\naggregate records which we call \"plant parts\". A plant part is a record which\ncorresponds to a particular collection of generators that all share an identical\nattribute and utility owner. E.g. all of the generators with unit_id=2, or all of the\ngenerators with coal as their primary fuel source.\n\nThe EIA data about power plants (from EIA 923 and 860) is reported in tables\nwith records that correspond to mostly generators and plants. Other datasets\n(cough cough FERC1) are less well organized and include plants, generators and\nother plant parts all in the same table without any clear labels. This plant part table\nis an attempt to create records corresponding to many different plant parts in order to\nconnect specific slices of EIA plants to other datasets.\n\nBecause generators are often owned by multiple utilities, another dimension of\nthis plant part table involves generating two records for each owner: one for the\nportion of the plant part they own and one for the plant part as a whole. The\nportion records are labeled in the ``ownership_record_type`` column as ``owned``\nand the total records are labeled as ``total``.\n\nThis table includes A LOT of duplicative information about EIA plants. It is primarily\nmeant for use as an input into the record linkage between FERC1 plants and EIA.\n\nThis table inherits canonicalized values for generators, plants, and utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n* Contains information from multiple raw inputs.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis table inherits canonicalized values for plants.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n* Contains information from multiple raw inputs.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis table inherits canonicalized values for utilities.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

Expect nulls.\n\n* FERC does not restrict respondents to report unique and non-duplicative plant records. There are sporadic instances of respondents reporting portions of plants and then the total plant (ex: unit 1, unit 2 and total). Use caution when aggregating.\n\n* FERC data is notoriously difficult to extract cleanly, and often contains free-form strings, non-labeled total rows and lack of IDs. See `Notable Irregularities <https://docs.catalyst.coop/pudl/en/latest/data_sources/ferc1.html#notable-irregularities>`_ for details.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis table is a concatenation of the following plant tables:\n\n* `core_ferc1__yearly_steam_plants_sched402`\n* `core_ferc1__yearly_hydroelectric_plants_sched406`\n* `core_ferc1__yearly_small_plants_sched410`\n* `core_ferc1__yearly_pumped_storage_plants_sched408`",

We used FERC 1's reported calculations to determine the most granular, non-duplicative records. The reported calculations are not always perfect - we've corrected many of them, but errors could still exist.\n\n* FERC data is notoriously difficult to extract cleanly, and often contains free-form strings, non-labeled total rows and lack of IDs. See `Notable Irregularities <https://docs.catalyst.coop/pudl/en/latest/data_sources/ferc1.html#notable-irregularities>`_ for details.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis table is derived from four FERC Form 1 accounting tables with nested calculations:\n\n* `core_ferc1__yearly_balance_sheet_assets_sched110`\n* `core_ferc1__yearly_utility_plant_summary_sched200`\n* `core_ferc1__yearly_plant_in_service_sched204`\n* `core_ferc1__yearly_depreciation_by_function_sched219`\n\nWe reconciled the nested calculations within these tables and then identified the most granular data across the tables.\nWe applied slight modifications to three columns (utility_type, plant_function & plant_status) as compared to the originally reported values in our core tables. The modifications were applied to either provide more specificity (i.e. we converted some `total` utility_type's into `electric`) or to condense similar categories for easier analysis (i.e. creating a `hydraulic_production` plant_function by combining `hydraulic_production_conventional` and `hydraulic_production_pumped_storage`).\nSee ``pudl.output.ferc1.Exploder`` for more details. This table was made entirely with support and direction from RMI.",

We used FERC 1's reported calculations to determine the most granular, non-duplicative records. The reported calculations are not always perfect - we've corrected many of them, but errors could still exist.\n\n* FERC data is notoriously difficult to extract cleanly, and often contains free-form strings, non-labeled total rows and lack of IDs. See `Notable Irregularities <https://docs.catalyst.coop/pudl/en/latest/data_sources/ferc1.html#notable-irregularities>`_ for details.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis table is derived from two FERC Form 1 accounting tables with nested calculations:\n\n* `core_ferc1__yearly_balance_sheet_liabilities_sched110`\n* `core_ferc1__yearly_retained_earnings_sched118`\n\nWe reconciled the nested calculations within these tables and then identified the most granular data across the tables.\nWe applied slight modifications to three columns (utility_type, plant_function & plant_status) as compared to the originally reported values in our core tables. The modifications were applied to either provide more specificity (i.e. we converted some `total` utility_type's into `electric`) or to condense similar categories for easier analysis (i.e. creating a `hydraulic_production` plant_function by combining `hydraulic_production_conventional` and `hydraulic_production_pumped_storage`).\nSee ``pudl.output.ferc1.Exploder`` for more details. This table was made entirely with support and direction from RMI.",

See `Notable Irregularities <https://docs.catalyst.coop/pudl/en/latest/data_sources/ferc1.html#notable-irregularities>`_ for details.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis table is derived from four FERC Form 1 accounting tables with nested calculations:\n\n* :ref:`core_ferc1__yearly_income_statements_sched114`\n* :ref:`core_ferc1__yearly_depreciation_summary_sched336`\n* :ref:`core_ferc1__yearly_operating_expenses_sched320`\n* :ref:`core_ferc1__yearly_operating_revenues_sched300`\n\nWe reconciled the nested calculations within these tables and then identified the most granular data across the tables.\nWe applied slight modifications to two columns (utility_type & plant_function) as compared to the originally reported values in our core tables. The modifications were applied to either provide more specificity (i.e. we converted some `total` utility_type's into `electric`) or to condense similar categories for easier analysis (i.e. creating a `hydraulic_production` plant_function by combining `hydraulic_production_conventional` and `hydraulic_production_pumped_storage`).\nSee ``pudl.output.ferc1.Exploder`` for more details. This table was made entirely with support and direction from RMI.",

      "description": "Annual time series of plant statistics for large hydroelectric generating plants.\n\n\nMost-recent data:\n  2024\n\n\nProcessing:\n  Data has been expanded into a wide/denormalized format, with IDs and codes accompanied by human-readable names and descriptions.\n\nSource:\n  FERC Form 1 -- Annual Report of Major Electric Utilities (Schedule 406)\n\nPrimary key:\n  record_id The best approximation for primary keys for this table would be: ``report_year``, ``utility_id_ferc1``, ``plant_name_ferc1``. FERC does not publish plant IDs. The main identifying column is ``plant_name_ferc1`` but that is a free-form string field and there are duplicate records.\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* The ``plant_type`` and ``construction_type`` are standardized into categorical values from free-form strings.\n\n* FERC does not restrict respondents to report unique and non-duplicative plant records. There are sporadic instances of respondents reporting portions of plants and then the total plant (ex: unit 1, unit 2 and total). Use caution when aggregating.\n\n* FERC data is notoriously difficult to extract cleanly, and often contains free-form strings, non-labeled total rows and lack of IDs. See `Notable Irregularities <https://docs.catalyst.coop/pudl/en/latest/data_sources/ferc1.html#notable-irregularities>`_ for details.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nLarge plants have an installed nameplate capacity of more than 10 MW.",

FERC does not publish plant IDs. The main identifying column is ``plant_name_ferc1`` but that is a free-form string field and there are duplicate records.\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* FERC does not restrict respondents to report unique and non-duplicative plant records. There are sporadic instances of respondents reporting portions of plants and then the total plant (ex: unit 1, unit 2 and total). Use caution when aggregating.\n\n* FERC data is notoriously difficult to extract cleanly, and often contains free-form strings, non-labeled total rows and lack of IDs. See `Notable Irregularities <https://docs.catalyst.coop/pudl/en/latest/data_sources/ferc1.html#notable-irregularities>`_ for details.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nAs reported in Schedule 408 of FERC Form 1.",

The primary key for this table would be record_id,\n  however a small number of these values are duplicated in 2021, 2022, and 2024.\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Contains columns which may appear categorical, but are actually free text.\n\n* FERC data is notoriously difficult to extract cleanly, and often contains free-form strings, non-labeled total rows and lack of IDs. See `Notable Irregularities <https://docs.catalyst.coop/pudl/en/latest/data_sources/ferc1.html#notable-irregularities>`_ for details.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis table has data about inter-utility power purchases. This includes how much electricity was purchased, how much it cost, and who it was purchased from. Unfortunately the field describing which other utility the power was being bought from (``seller_name``) is poorly standardized, making it difficult to correlate with other data.\n\nPurchased Power is considered FERC Account 555 according to FERC's Uniform System of Accounts.

We used FERC 1's reported calculations to determine the most granular, non-duplicative records. The reported calculations are not always perfect - we've corrected many of them, but errors could still exist.\n\n* FERC data is notoriously difficult to extract cleanly, and often contains free-form strings, non-labeled total rows and lack of IDs. See `Notable Irregularities <https://docs.catalyst.coop/pudl/en/latest/data_sources/ferc1.html#notable-irregularities>`_ for details.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis table is derived from seven FERC Form 1 accounting tables with nested calculations. We reconciled these nested calculations and then identified the most granular data across the tables.\nHere are the three direct upstream inputs - the two ``detailed`` tables have several ``core_ferc1`` inputs each:\n\n* :ref:`out_ferc1__yearly_detailed_balance_sheet_assets`\n* :ref:`out_ferc1__yearly_detailed_balance_sheet_liabilities`\n* :ref:`core_ferc1__yearly_operating_expenses_sched320`\n\nWe applied slight modifications to three columns (utility_type, plant_function & plant_status) as compared to the originally reported values in our core tables. The modifications were applied to either provide more specificity (i.e. we converted some `total` utility_type's into `electric`) or to condense similar categories for easier analysis (i.e. creating a `hydraulic_production` plant_function by combining `hydraulic_production_conventional` and `hydraulic_production_pumped_storage`).\nSee ``pudl.output.ferc1.Exploder`` for more details. This table was made entirely with support and direction from RMI.",

      "description": "Annual time series of utilities' electric sales from all rate schedules in effect throughout the year.\n\n\nMost-recent data:\n  2024\n\n\nProcessing:\n  Data has been expanded into a wide/denormalized format, with IDs and codes accompanied by human-readable names and descriptions.\n\nSource:\n  FERC Form 1 -- Annual Report of Major Electric Utilities (Schedule 304)\n\nPrimary key:\n  This table has no primary key.\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Some columns contain subtotals; use caution when choosing columns to aggregate.\n\n* Values in rate_schedule_description are free-form strings.\n\n* Data prior to 2021 does not include information in columns: rate_schedule_type and billing_status.\n\n* Units of revenue_per_kwh are suspected to include a mix of dollars and possibly cents.\n\n* FERC data is notoriously difficult to extract cleanly, and often contains free-form strings, non-labeled total rows and lack of IDs. See `Notable Irregularities <https://docs.catalyst.coop/pudl/en/latest/data_sources/ferc1.html#notable-irregularities>`_ for details.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThe pre-2021 data in this table (extracted from FoxProDB vs. XBRL) is\nextremely unstructured. Where the post-2020 data (from XBRL) sorts the data\ninto rate schedule types: residential, industrial, commercial,\npublic_lighting, public_authorities, railroads, interdepartmental,\nprovision_for_rate_refund, commercial_and_industrial, total, and billing\nstatus: billed, unbilled, total, the pre-2021 data stuffs all of that\ninformation (if you're lucky) into the rate_schedule_description column.\nThere's no point trying to parse through the pre 2021\nrate_schedule_description column en masse because it's just too messy. The\ncontents of rate_schedule_description often contain numbers and acronyms\nthat have little to no meaning out of context. The table is structured\nsomewhat like the FERC1 small generators table with headings about rate\nstructure type also embedded into the rate_schedule_description column. To\nall who dare, beware.\n\nThis table is a combination of one pre-2021 (DBF) table and nine post-2020\n(XBRL) tables--one for each rate schedule type plus totals--hence increase\nin data clarity post-2020. The rate_schedule_type and billing_status\ncolumns are only relevant for post-2020 data as they can be reliably parsed\nfrom each of the tables and incorporated into columns. The\nrate_schedule_description is supposed to contain sub-rate_schedule_type\nnames for charges (Ex: Residential 1, Residential 2, etc.). However, the\npre-2021 data contains a little bit of everything (or nothing) and the\npost-2020 has some totals or wonky data thrown in. That's to say, even when\nworking with post-2020 data, be wary of aggregating the data. That's what\nthe \"total\" rows are for.\n\nThe values that come from from the totals table are marked with the string\n\"total\" in the rate_schedule_description column. The totals table is a\nproduct of the transition to XBRL, so these distinguishable totals are only\navailable for data post-2020 (otherwise you could try keyword searching for\n\"total\" in rate_schedule_description). The total table contains two types of\ntotals, the utility totals across all rate schedules in a given year\n(marked with rate_schedule_description = \"total\" and rate_schedule_type =\n\"total\") and each of the utility's individual rate schedule totals in a\ngiven year (marked with rate_schedule_description = \"total\" and\nrate_schedule_type = \"residential\" or any other rate schedule type).\n\nThe rate schedule based XBRL tables only report billed values whereas the\ntotal tables report billed, unbilled, and total values. (See the column\ndescription for more info on the difference between billed and unbilled).\nThis is important to consider if you're endeavoring to compare the subtotal\nvalues with the total values. We have not attempted to fix or verify any\nsubtotals or totals that don't add up.\n\nAnother important note is the possibility of unit discrepancies in certain\ncolumns. The revenue_per_kwh column does not specify reporting units, and\ncloser inspection of the data reveals two clear peaks approximate two orders\nof magnitude apart. This indicates that values may be reported in both\ndollars and cents. However, because the price of energy per kwh varies\nso much regionally, we cannot guarantee which is which and have not put\nany cleaning mechanisms in place to account for this.",

      "description": "Annual time series of plant statistics for internal combustion plants, gas turbine-plants, conventional hydro plants, and pumped storage plants with less than 10 MW installed nameplate capacity and steam plants with less than 25 MW installed nameplate capacity.\n\n\nMost-recent data:\n  2024\n\n\nProcessing:\n  Data has been expanded into a wide/denormalized format, with IDs and codes accompanied by human-readable names and descriptions.\n\nSource:\n  FERC Form 1 -- Annual Report of Major Electric Utilities (Schedule 410)\n\nPrimary key:\n  record_id The best approximation for primary keys for this table would be: ``report_year``, ``utility_id_ferc1``, ``plant_name_ferc1``. FERC does not publish plant IDs. The main identifying column is ``plant_name_ferc1`` but that is a free-form string field and there are duplicate records.\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* FERC does not restrict respondents to report unique and non-duplicative plant records. There are sporadic instances of respondents reporting portions of plants and then the total plant (ex: unit 1, unit 2 and total). Use caution when aggregating.\n\n* FERC data is notoriously difficult to extract cleanly, and often contains free-form strings, non-labeled total rows and lack of IDs. See `Notable Irregularities <https://docs.catalyst.coop/pudl/en/latest/data_sources/ferc1.html#notable-irregularities>`_ for details.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nAs reported on FERC Form 1 Schedule 410 (pages 410-411)\nand extracted from the FERC Visual FoxPro and XBRL. See our\n``pudl.extract.ferc1.TABLE_NAME_MAP_FERC1`` for links to the raw tables.\n\nThe raw version of this table is more like a digitized PDF than an actual data table.\nThe rows contain lots of information in addition to what the columns might suggest.\nFor instance, a single column may contain header rows, note rows, and total rows. This\nextraneous information is useful, but it prevents proper analysis when mixed in with the\nrest of the values data in the column. We employ a couple of data transformations to\nextract these rows from the data and preserve some of the information they contain\n(fuel type, plant type, FERC license, or general notes about the plant) in separate\ncolumns.",

The main identifying column is ``plant_name_ferc1`` but that is a free-form string field and there are duplicate records.\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* FERC does not restrict respondents to report unique and non-duplicative plant records. There are sporadic instances of respondents reporting portions of plants and then the total plant (ex: unit 1, unit 2 and total). Use caution when aggregating.\n\n* FERC data is notoriously difficult to extract cleanly, and often contains free-form strings, non-labeled total rows and lack of IDs.

Each record of this table is supposed to represent one stretch of a transmission line, but there are no IDs and many nulls in the fields which would nominally distinguish unique transmission lines.\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Contains columns which may appear categorical, but are actually free text.\n\n* Some columns contain subtotals; use caution when choosing columns to aggregate.\n\n* FERC data is notoriously difficult to extract cleanly, and often contains free-form strings, non-labeled total rows and lack of IDs. See `Notable Irregularities <https://docs.catalyst.coop/pudl/en/latest/data_sources/ferc1.html#notable-irregularities>`_ for details.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nInformation describing transmission lines, the cost of lines, annual operating and capital expenses, etc. This table includes transmission lines having nominal voltage of 132 kilovolts or greater. Transmission lines below these voltages are required to be reported in group totals only for each voltage.",

See `Notable Irregularities <https://docs.catalyst.coop/pudl/en/latest/data_sources/ferc1.html#notable-irregularities>`_ for details.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis table uses hourly\nelectricity demand and information about service territories to estimate the total\nhourly electricity demand for each US state. Hourly demand is drawn from the FERC\n714, which reports at the balancing authority and utility level. Service territories\nfor utilities and balancing authorities are inferred from information in the EIA 861,\nincluding the counties served by each utility and the utilities that make up each\nbalancing authority.\n\nThis table uses the total electricity sales by state reported in the EIA 861 as a\nscaling factor to ensure that the magnitude of electricity sales is roughly correct, and\nobtains the shape of the demand curve from the hourly planning area demand reported in\nthe FERC 714.\n\nThis table includes the state FIPS codes - see :ref:`out_censusdp1tract__states` for\nadditional information about FIPS state codes.",

Note that the state and county FIPS columns can be null. Otherwise the natural primary key would be: ['respondent_id_ferc714', 'report_date', 'county_id_fips']. The state FIPS code is not part of the primary key because the first two digits of the county FIPS code indicate the state.\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Contains information from multiple raw inputs.\n\n* FERC data is notoriously difficult to extract cleanly, and often contains free-form strings, non-labeled total rows and lack of IDs.

See `Harvesting <https://docs.catalyst.coop/pudl/en/latest/data_dictionaries/usage_warnings.html#harvested>`_ for details, and see `Entity Resolution Methodology <https://docs.catalyst.coop/pudl/en/latest/methodology/entity_resolution.html>`_ for a fuller conceptual overview.\n\n* Contains information from multiple raw inputs.\n\n* FERC data is notoriously difficult to extract cleanly, and often contains free-form strings, non-labeled total rows and lack of IDs. See `Notable Irregularities <https://docs.catalyst.coop/pudl/en/latest/data_sources/ferc1.html#notable-irregularities>`_ for details.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis table\nanswers the question \"What EIA data reported about plants or generators should be\nassociated with a given plant record found in the FERC Form 1?\"\n\nEach record in this table corresponds to a single FERC Form 1 record reported in one of\nseveral tables describing power plants (large steam, hydro, small, etc.). These FERC\nrecords can correspond to an entire plant, individual generators within a plant, all\ngenerators in a plant with the same prime mover type, or just the respondent's ownership\nshare of any of those categories (or other categories). Furthermore, the same utility\nmay report the same plant in different ways in different years.\n\nThe EIA data associated with each FERC plant record comes from our Plant Parts EIA\ntable, :ref:`out_eia__yearly_plant_parts`.\nThe EIA data in each record represents an aggregation of several slices of an EIA\nplant, across both physical characteristics and utility ownership.\n\nThis table inherits canonicalized values for generators and plants.\nEIA reports many attributes in many different tables across\nEIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL\ncollects all instances of these values and and chooses a canonical value. By default,\nPUDL chooses the most consistently reported value of a given attribute as long as it\nis at least 70% of the given instances reported. If an attribute was reported\ninconsistently across the original EIA tables, then it will show up as a\nnull value. See :doc:`/methodology/entity_resolution` for a conceptual overview of\nthis process.",

PUDL chooses the most consistent borrower name to facilitate cross-referencing even if that means some values will differ from the raw sources.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThere are some peak demand dates that have an hour component and others that don't. This is because there is inconsistent reporting of peak_demand_hour in the raw data. If there is no hour reported, we record the hour as 0 and only the date will show in the data.",

This table has no primary key because some borrowers report multiple loan values from the same entity in a given year.\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Borrower name data has been drawn from reported values over multiple years and tables of data which are not always consistent with each other. PUDL chooses the most consistent borrower name to facilitate cross-referencing even if that means some values will differ from the raw sources.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThis table also includes loan guarantees where the RUS borrower backs a loan from another entity and is therefore liable to pay any remaining balance should the original borrower default.",

      "description": "Annual time series of costs of net energy generated by plant.\n\n\nMost-recent data:\n  2021\n\n\nProcessing:\n  Data has been expanded into a wide/denormalized format, with IDs and codes accompanied by human-readable names and descriptions.\n\nSource:\n  USDA RUS Form 12 -- Financial and Operating Report: Electric Power Supply (Part F - Section D)\n\nPrimary key:\n  This table has no primary key. This table has no primary key because there is one plant (Walter Scott) that has duplicate records every year. Based on other RUS-12 tables, it is likely that these duplicate records are the borrowers' ownership portion of the plant as well as the total plant but there is no clear indication in this table.\n\nThe primary key of this table otherwise would be: ['report_date', 'borrower_id_rus', 'plant_name_rus', 'cost_group', 'cost_type'].\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Some columns contain subtotals; use caution when choosing columns to aggregate.\n\n* Borrower name data has been drawn from reported values over multiple years and tables of data which are not always consistent with each other. PUDL chooses the most consistent borrower name to facilitate cross-referencing even if that means some values will differ from the raw sources.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThe cost column in this table is expected to be largely non-null, the cost_per_mwh and cost_per_mmbtu columns only apply to some cost_type's and even plant_type's and thus are expected to contain many nulls.",

      "description": "Annual time series of plant factors and maximum demand for plants owned by RUS borrowers.\n\n\nMost-recent data:\n  2021\n\n\nProcessing:\n  Data has been expanded into a wide/denormalized format, with IDs and codes accompanied by human-readable names and descriptions.\n\nSource:\n  USDA RUS Form 12 -- Financial and Operating Report: Electric Power Supply (Parts D, E, F IC, F CC, G - Section C)\n\nPrimary key:\n  This table has no primary key. The primary key for this table would be report_date, borrower_id_rus, plant_name_rus, and plant_type but the plant_type column is not reported before 2009 causing lots of duplicate records. Because none of the other fields are static year-over-year, there is no reliable way to backfill the plant_type column in instances where there are different plant_types reported for the same plant in later years.\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Borrower name data has been drawn from reported values over multiple years and tables of data which are not always consistent with each other. PUDL chooses the most consistent borrower name to facilitate cross-referencing even if that means some values will differ from the raw sources.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThe plant_type field was only included in the data starting in 2009. We backfill records with only one reported plant_type per borrower/plant name/year. Records with multiple plant_types per borrower/plant name/year are left with null plant_type because there is no reliable way to determine which plant_type is associated with which record back in time. Plants who's names are reported differently pre and post 2009 will also miss being backfilled.",

      "description": "Annual time series of labor and payroll information for plants owned by RUS borrowers.\n\n\nMost-recent data:\n  2021\n\n\nProcessing:\n  Data has been expanded into a wide/denormalized format, with IDs and codes accompanied by human-readable names and descriptions.\n\nSource:\n  USDA RUS Form 12 -- Financial and Operating Report: Electric Power Supply (Parts D, E, F, G - Section B)\n\nPrimary key:\n  This table has no primary key. The primary key should be report_date, borrower_id_rus, plant_name_rus, and plant_type, but this table did not report plant_type before 2009 and there are respondents who report multiple rows per plant pre-2009. The data cannot be backfilled because there is no way to distinguish between duplicate rows pre-2009.\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Some columns contain subtotals; use caution when choosing columns to aggregate.\n\n* Borrower name data has been drawn from reported values over multiple years and tables of data which are not always consistent with each other. PUDL chooses the most consistent borrower name to facilitate cross-referencing even if that means some values will differ from the raw sources.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nNote the lack of plant_type pre-2009 leading to a lack of reliable primary keys.\n\nPlant-level data from :ref:`core_rus12__yearly_plant_operations_by_plant` can be matched to data from this table, but you must also join this data usingthe ``borrower_id_rus`` column as well as the ``report_date`` and ``plant_name``. This is because the :ref:`core_rus12__yearly_plant_operations_by_plant` table includes records from each plant owner. The RUS instructions note that:\n\nyou should use caution when using total plant data since there are cases where more than one Borrower shares units at the same plant which means that you will be getting duplicate plant total records (and there is no guarantee that the total plant records entered by two borrowers for the same plant will be identical).",

      "description": "Annual time series of borrower portion of plant operational data including fuel consumption and operational hours.\n\n\nMost-recent data:\n  2021\n\n\nProcessing:\n  Data has been expanded into a wide/denormalized format, with IDs and codes accompanied by human-readable names and descriptions.\n\nSource:\n  USDA RUS Form 12 -- Financial and Operating Report: Electric Power Supply (Part D, E, F (CC), F (IC) & G - Section A)\n\nPrimary key:\n  This table has no primary key. This table has no primary key because there are a handful of plants that have duplicate records. The primary key of this table otherwise would be: [`report_date`, `borrower_id_rus`, `plant_name_rus`, `plant_name_rus`, `unit_id_rus`, `plant_type`, `is_full_ownership_portion`, `is_partly_owned_by_borrower`].\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Borrower name data has been drawn from reported values over multiple years and tables of data which are not always consistent with each other. PUDL chooses the most consistent borrower name to facilitate cross-referencing even if that means some values will differ from the raw sources.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThe data in this table comes from five different portions of RUS 12 corresponding to different plant types (steam, hydroelectric, combined_cycle, internal_combustion and nuclear).\nThe original form includes plant operations data for each plant type reported in multiple ways: with records corresponding to the portion of plants that borrowers own as well as the whole plant. We split these records into two tables, :ref:`core_rus12__yearly_plant_operations_by_borrower`, which contains records reported at the borrower level, and  :ref:`core_rus12__yearly_plant_operations_by_plant`, which contains records reported at the plant level.Records that are wholly owned by one borrower show up in both :ref:`core_rus12__yearly_plant_operations_by_borrower` and :ref:`core_rus12__yearly_plant_operations_by_plant`.\n\nThere are two boolean columns used to delineate which records are associated with the borrowers' share vs the whole plant - which is documented in ``_OR_PowerSupply Plant File Documentation.rtf`` in the newer years in the RUS 12 archive. One of these two fields - ``is_partly_owned_by_borrower`` - was not reported before 2009. For the pre-2009 years, we assume that all records that report TRUE for is_full_ownership_portion should end up in the by-plant table while all records should end up in the by-borrower portion of the table.Like the post-2009 records, this involves records from the original tables ending up in both of these PUDL tables.\n\nAlso there are two cleaning steps that we performed that alter the original data slightly:\n\n* **One dropped with unexpected ownership label and duplicate data**: There is a   Wisdom steam plant record that is labeled to be both fully owned by borrower   and partly owned for one year, which is an unexpected combo based on the   `_OR_PowerSupply Plant File Documentation.rst` documentation file in the rus12   archive. Luckily this plant has exactly the same records as the other Wisdom steam  plant that year with more expected ownership labels.* **Replaced two string values for unit_id_rus**: There are two instances from 2018   of unit_id_rus's that have string values in them - ``WSL GT 12`` and ``WSL ST 10``.   Based on pre-cleaned data, we were able to clearly identify that we can use just   the numeric values in these bad strings - 12 and 10 respectively. This enables us   to have an integer type for this unit_id_rus column.",

      "description": "Annual time series of whole plant operational data including fuel consumption and operational hours.\n\n\nMost-recent data:\n  2021\n\n\nProcessing:\n  Data has been expanded into a wide/denormalized format, with IDs and codes accompanied by human-readable names and descriptions.\n\nSource:\n  USDA RUS Form 12 -- Financial and Operating Report: Electric Power Supply (Part D, E, F (CC), F (IC) & G - Section A)\n\nPrimary key:\n  This table has no primary key. This table has no primary key because there are a handful of plants that have duplicate records. The primary key of this table otherwise would be: [`report_date`, `borrower_id_rus`, `plant_name_rus`, `plant_name_rus`, `unit_id_rus`, `plant_type`, `is_full_ownership_portion`, `is_partly_owned_by_borrower`].\n\n\nUsage Warnings\n^^^^^^^^^^^^^^\n\n\n* Borrower name data has been drawn from reported values over multiple years and tables of data which are not always consistent with each other. PUDL chooses the most consistent borrower name to facilitate cross-referencing even if that means some values will differ from the raw sources.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThe data in this table comes from five different portions of RUS 12 corresponding to different plant types (steam, hydroelectric, combined_cycle, internal_combustion and nuclear).\nThe original form includes plant operations data for each plant type reported in multiple ways: with records corresponding to the portion of plants that borrowers own as well as the whole plant. We split these records into two tables, :ref:`core_rus12__yearly_plant_operations_by_borrower`, which contains records reported at the borrower level, and  :ref:`core_rus12__yearly_plant_operations_by_plant`, which contains records reported at the plant level.Records that are wholly owned by one borrower show up in both :ref:`core_rus12__yearly_plant_operations_by_borrower` and :ref:`core_rus12__yearly_plant_operations_by_plant`.\n\nThere are two boolean columns used to delineate which records are associated with the borrowers' share vs the whole plant - which is documented in ``_OR_PowerSupply Plant File Documentation.rtf`` in the newer years in the RUS 12 archive. One of these two fields - ``is_partly_owned_by_borrower`` - was not reported before 2009. For the pre-2009 years, we assume that all records that report TRUE for is_full_ownership_portion should end up in the by-plant table while all records should end up in the by-borrower portion of the table.Like the post-2009 records, this involves records from the original tables ending up in both of these PUDL tables.\n\nAlso there are two cleaning steps that we performed that alter the original data slightly:\n\n* **One dropped with unexpected ownership label and duplicate data**: There is a   Wisdom steam plant record that is labeled to be both fully owned by borrower   and partly owned for one year, which is an unexpected combo based on the   `_OR_PowerSupply Plant File Documentation.rst` documentation file in the rus12   archive. Luckily this plant has exactly the same records as the other Wisdom steam  plant that year with more expected ownership labels.* **Replaced two string values for unit_id_rus**: There are two instances from 2018   of unit_id_rus's that have string values in them - ``WSL GT 12`` and ``WSL ST 10``.   Based on pre-cleaned data, we were able to clearly identify that we can use just   the numeric values in these bad strings - 12 and 10 respectively. This enables us   to have an integer type for this unit_id_rus column..\n\nPlant-level data can be matched to the :ref:core_rus12__yearly_plant_labor` and forthcoming core_rus12__yearly_plant_factors_and_maximum_demand, which report Section B and C data for all plants. The RUS instructions note that:\n\nyou should use caution when using total plant data since there are cases where more than one Borrower shares units at the same plant which means that you will be getting duplicate plant total records (and there is no guarantee that the total plant records entered by two borrowers for the same plant will be identical).",

PUDL chooses the most consistent borrower name to facilitate cross-referencing even if that means some values will differ from the raw sources.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThere are a few layers of nesting in this table, which can be distinguished by the categories in the `utility_plant_group` column:\n\n * intangible_plant: only has one total utility_plant_item\n * production_plant: has several sub-component utility_plant_item and a standard total\n * transmission_plant: has several sub-component utility_plant_item and a standard total\n * distribution_plant: has several sub-component utility_plant_item and a standard total\n * electric_plant_in_service: has two sub-components and a total which includes those sub-components and the totals of the above categories\n * utility_plant_in_service: has several sub-components and the total is the sum of those sub-components as well as the total of electric_plant_in_service\n * total_utility_plant: has one sub-component and the total is the sum of the sub-component and utility_plant_in_service",

PUDL chooses the most consistent borrower name to facilitate cross-referencing even if that means some values will differ from the raw sources.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nA number of records report purchases from an unspecified entity.

PUDL chooses the most consistent borrower name to facilitate cross-referencing even if that means some values will differ from the raw sources.\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nNote that according to RUS, 'underbuild in overhead lines or joint runs in underground installations do not increase the number of line miles except for distribution underbuild on transmission poles. In such cases, distribution pole line miles would be increased by the number of underbuild miles involved.'",

To convert to units of power, the user must multiply by the installed capacity within the county.\n\n* Hourly capacity factors are spatially averaged across each county over the contiguous USA. There are a handful of counties that are too small to pick up representation on the HRRR operational forecast grid. As such, these counties will have no wind or solar power production curves.\n\n* Due to power production performance being correlated with panel temperatures, during cold sunny periods, some solar capacity factor values are greater than 1 (but less that 1.1).\n\n\n\n\n\nAdditional Details\n^^^^^^^^^^^^^^^^^^\n\nThe data in this table were produced by Vibrant Clean Energy, and are licensed to the public under the Creative Commons Attribution 4.0 International license (CC-BY-4.0).\n\nThe technologies provided are:\n\n1) Onshore wind assuming a 100m hub height and 120m rotor diameter;\n\n2) Offshore wind assuming a 140m hub height and 120m rotor diameter;\n\n3) Utility solar assuming a fixed axis panel tilted at latitude.\n\nThe foundation of the capacity factors provided here is the NOAA HRRR operational numerical weather prediction model. The HRRR covers the entire contiguous US at a horizontal resolution of 3 km. Forecasts are initialized each hour of the year. Forecast hour two (2) is used as the input data for the power algorithms. This forecast hour is chosen to trade-off the impact of the measurement and data assimilation procedure of the HRRR with the physics of the model to derive the most complete picture of the atmosphere at the forecast time horizon. \n\nFor wind capacity factors: vertical slices of the atmosphere are considered across the defined rotor swept area. Bringing together wind speed, density, temperature and icing information, a power capacity is estimated using a representative power coefficient (Cp) curve to determine the power from a given wind speed, atmospheric density and temperature. There is no wake modeling included in the dataset.\n\nFor solar capacity factors: pertinent surface weather variables are pulled such as incoming short wave radiation, direct normal irradiance (calculated in the HRRR 2016 forward), surface temperature and other parameters. These are used in a non-linear I-V curve translation to power capacity factors.",

Due to power production performance being correlated with panel temperatures, during cold sunny periods, some solar capacity factor values are greater than 1 (but less that 1.1).All values are based on outputs from the NOAA HRRR operational numerical weather prediction model. Capacity factors are normalized to unity for maximal power output. Pertinent surface weather variables are pulled such as incoming short wave radiation, direct normal irradiance (calculated in the HRRR 2016 forward), surface temperature and other parameters. These are used in a non-linear I-V curve translation to power capacity factors."
