coalmine_eia923

Attributes of coal mines reporting deliveries in the Fuel Receipts and Costs table, via EIA-923 Schedule 2, Part C.

This table is produced during the transformation of fuel delivery data, in order to produce a better normalized database. The same coalmines report many individual deliveries, and repeating their attributes many times in the fuel receipts and costs table is duplicative. Unfortunately the coalmine attributes do not generally use a controlled vocabulary or well defined IDs and so in practice there are many distinct records in this table that correspond to the same mines in reality.

We have not yet taken the time to rigorously clean this data, but it could be linked with both Mining Safety and Health Administration (MSHA) and USGS data to provide more insight into where coal is coming from, and what the employment and geological context is for those supplies.

denorm_boiler_fuel_eia923

EIA-923 Monthly Boiler Fuel Consumption and Emissions, from EIA-923 Schedule 3.

Reports the quantity of each type of fuel consumed by each boiler on a monthly basis, as well as the sulfur and ash content of those fuels. Fuel quantity is reported in standard EIA fuel units (tons, barrels, Mcf).

denorm_fuel_receipts_costs_eia923

Data describing fuel deliveries to power plants, reported in EIA-923 Schedule 2, Part A.

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.

There can be a significant delay between the receipt of fuel and its consumption, so using this table to infer monthly attributes associated with power generation may not be entirely accurate. However, this is the most granular data we have describing fuel costs, and we use it in calculating the marginal cost of electricity for individual generation units.

Under some circumstances utilities are allowed to treat the price of fuel as proprietary business data, meaning it is redacted from the publicly available spreadsheets. It's still reported to EIA and influences the aggregated (state, region, annual, etc.) fuel prices they publish. From 2009-2021 about 1/3 of all prices are redacted. The missing data is not randomly distributed. Deregulated markets dominated by merchant generators (independent power producers) redact much more data, and natural gas is by far the most likely fuel to have its price redacted. This means, for instance, that the entire Northeastern US reports essentially no fine-grained data about its natural gas prices.

Additional data which we haven't yet integrated is available in a similar format from 2002-2008 via the EIA-423, and going back as far as 1972 from the FERC-423. Browse or query this table in Datasette.

Whenever possible, we use this generator-level net generation to estimate the heat rates of generation units and the marginal cost of electricity on a per-generator basis, but those calculations depend on plant-level fuel costs and sometimes uncertain or incomplete boiler-generator associations.

Note that a small number of respondents only report annual net generation, and all of it is reported in December. Browse or query this table in Datasette.

electricity_sales_by_rate_schedule_ferc1

The pre-2021 data in this table (extracted from FoxProDB vs. XBRL) is extremely unstructured. Where the post-2020 data (from XBRL) sorts the data into rate schedule types: residential, industrial, commercial, public_lighting, public_authorities, railroads, interdepartmental, provision_for_rate_refund, commercial_and_industrial, total, and billing status: billed, unbilled, total, the pre-2021 data stuffs all of that information (if you're lucky) into the rate_schedule_description column. There's no point trying to parse through the pre 2021 rate_schedule_description column en masse because it's just too messy. The contents of rate_schedule_description often contain numbers and acronyms that have little to no meaning out of context. The table is structured somewhat like the FERC1 small generators table with headings about rate structure type also embedded into the rate_schedule_description column. To all who dare, beware.

This table is a combination of one pre-2021 (DBF) table and nine post-2020 (XBRL) tables–one for each rate schedule type plus totals–hence increase in data clarity post-2020. The rate_schedule_type and billing_status columns are only relevant for post-2020 data as they can be reliably parsed from each of the tables and incorporated into columns. The rate_schedule_description is supposed to contain sub-rate_schedule_type names for charges (Ex: Residential 1, Residential 2, etc.). However, the pre-2021 data contains a little bit of everything (or nothing) and the post-2020 has some totals or wonky data thrown in. That's to say, even when working with post-2020 data, be wary of aggregating the data. That's what the "total" rows are for.

The values that come from from the totals table are marked with the string "total" in the rate_schedule_description column. The totals table is a product of the transition to XBRL, so these distinguishable totals are only available for data post-2020 (otherwise you could try keyword searching for "total" in rate_schedule_description). The total table contains two types of totals, the utility totals accross all rate schedules in a given year (marked with rate_schedule_description = "total" and rate_schedule_type = "total") and each of the utility's individual rate schedule totals in a given year (marked with rate_schedule_description = "total" and rate_schdedule_type = "residential" or any other rate schdedule type).

The rate schedule based XBRL tables only report billed values whereas the total tables report billed, unbilled, and total values. (See the column description for more info on the difference between billed and unbilled). This is important to consider if you're endeavoring to compare the subtotal values with the total values. We have not attempted to fix or verify any subtotals or totals that don't add up.

Another important note is the possability of unit discrepancies in certain columns. The revenue_per_kwh column does not specify reporting units, and closer inspection of the data reveals two clear peaks approximate two orders of magnitude appart. This indicates that values may be reported in both dollars and cents. However, because the price of energy per kwh varies so much regionally, we cannot guarantee which is which and have not put any cleaning mechanisms in place to account for this. Browse or query this table in Datasette.

This crosswalk table comes from the EPA's Github repo camd-eia-crosswalk: https://github.com/USEPA/camd-eia-crosswalk. It's purpose is to connect EPA units with EIA plants, boilers, and generators. The camd-eia-crosswalk README and our Data Source documentation page on EPA Hourly Continuous Emission Monitoring System (CEMS) depict the complicated relationship between EIA and EPA data, specifically the nature of EPA vs. EIA "units" and the level of granularity that one can connect the two sources.

The crosswalk table is generated using EIA data from 2018 meaning that any plants that have shifted before or since then aren't accurately reflected in the data. We're hoping to create a temporal version of the crosswalk at some point.

Our version of the crosswalk clarifies some of the column names and removes unmatched rows. The pudl.etl.glue_assets.epacamd_eia() function doc strings explain what changes are made from the EPA's version. Browse or query this table in Datasette.

epacamd_eia_subplant_ids

This table is an augmented version of the epacamd_eia crosswalk table which initally comes from the EPA's Github repo camd-eia- crosswalk: https://github.com/USEPA/camd-eia-crosswalk. It's purpose is to connect EPA units with EIA units, and generators.

This table identifies subplants within plant_ids, which are the smallest coherent units for aggregation. plant_id refers to a legal entity that often contains multiple distinct power plants, even of different technology or fuel types.

EPA CEMS data combines information from several parts of a power plant: * emissions from smokestacks * fuel use from combustors * electricty production from generators But smokestacks, combustors, and generators can be connected in complex, many- to-many relationships. This complexity makes attribution difficult for, as an example, allocating pollution to energy producers. Furthermore, heterogeneity within plant_ids make aggregation to the parent entity difficult or inappropriate.

This table inherits from the EPA's crosswalk, the ID's from EPA CAMD hourly_emissions_epacems table itself, the boiler_generator_assn_eia860 table and the generators_eia860 table. While the epacamd_eia table is the core backbone of the table, EPA CAMD id's ensure there is complete coverage of EPA CAMD reporting units. The EIA 860 table addition ensures there is also complete coverage of those units as well.

For more information about the how this subplant_id is made, see the documentation for pudl.etl.glue_assets.make_subplant_ids and pudl.etl.glue_assets.update_subplant_ids from: https://catalystcoop-pudl.readthedocs.io/en/latest/autoapi/index.html

But by analyzing the relationships between combustors and generators, as provided in the epacamd_eia crosswalk, we can identify distinct power plants. These are the smallest coherent units of aggregation.

This table does not have primary keys because 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 because ~2 percent of all EPA CAMD records are not successfully mapped to EIA generators.

fuel_receipts_costs_eia923

Data describing fuel deliveries to power plants, reported in EIA-923 Schedule 2, Part A.

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.

There can be a significant delay between the receipt of fuel and its consumption, so using this table to infer monthly attributes associated with power generation may not be entirely accurate. However, this is the most granular data we have describing fuel costs, and we use it in calculating the marginal cost of electricity for individual generation units.

Under some circumstances utilities are allowed to treat the price of fuel as proprietary business data, meaning it is redacted from the publicly available spreadsheets. It's still reported to EIA and influences the aggregated (state, region, annual, etc.) fuel prices they publish. From 2009-2021 about 1/3 of all prices are redacted. The missing data is not randomly distributed. Deregulated markets dominated by merchant generators (independent power producers) redact much more data, and natural gas is by far the most likely fuel to have its price redacted. This means, for instance, that the entire Northeastern US reports essentially no fine-grained data about its natural gas prices.

Additional data which we haven't yet integrated is available in a similar format from 2002-2008 via the EIA-423, and going back as far as 1972 from the FERC-423. Browse or query this table in Datasette.

generation_eia923

EIA-923 Monthly Generating Unit Net Generation. From EIA-923 Schedule 3.

Reports the net electricity generated by each reporting generator on a monthly basis. This is the most granular information we have about how much electricity individual generators are producing, but only about half of all the generation reported in the generation_fuel_eia923 appears in this table due to the different reporting requirements imposed on different types and sizes of generators.

Whenever possible, we use this generator-level net generation to estimate the heat rates of generation units and the marginal cost of electricity on a per-generator basis, but those calculations depend on plant-level fuel costs and sometimes uncertain or incomplete boiler-generator associations.

Note that a small number of respondents only report annual net generation, and all of it is reported in December. Browse or query this table in Datasette.

Then, these allocations are aggregated to unique generator, prime mover, and energy source code combinations. 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 generation_fuel_eia923 records will be associated similarly between these two generators. Allocated net generation will still be proportional to each generator's net generation or capacity. Browse or query this table in Datasette.

Then, these allocations are aggregated to unique generator, prime mover, energy source code, and owner combinations. Note that the utility_id_eia in this table refers to the OWNER of the generator, not the operator. 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 generation_fuel_eia923 records will be associated similarly between these two generators.

generation_fuel_eia923

EIA-923 Monthly Generation and Fuel Consumption Time Series. From EIA-923 Schedule 3.

Monthly electricity generation and fuel consumption reported for each combination of fuel and prime mover within a plant. This data can't be easily linked to individual boilers, generators, and generation units, but it is provides the most complete coverage of fuel consumption and electricity generation for the entire generation fleet. We use the primary fuels and prime movers reported for each generator along with their capacities to attribute fuel consumption and generation when it isn't directly reported in the generation_eia923 and boiler_fuel_eia923 tables in order to calculate capacity factors, heat rates, and the marginal cost of electricity.

The table makes a distinction between all fuel consumed and fuel consumed for electricity generation because some units are also combined heat and power (CHP) units, and also provide high temperature process heat at the expense of net electricity generation.

mcoe_monthly

Monthly generator capacity factor, heat rate, fuel cost per MMBTU and fuel cost per MWh. These calculations are based on the allocation of net generation reported on the basis of plant, prime mover and energy source to individual generators. Heat rates by generator-month are estimated by using allocated estimates for per-generator net generation and fuel consumption as well as the boiler_fuel_eia923 table, which reports fuel consumed by boiler. Heat rates are necessary to estimate the amount of fuel consumed by a generation unit, and thus the fuel cost per MWh generated. Plant specific fuel prices are taken from the fuel_receipts_costs_eia923 table, which only has ~70% coverage, leading to some generators with heat rate estimates still lacking fuel cost estimates.

plants_small_ferc1

The generating 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. As reported on FERC Form 1 Schedule 410 (pages 410-411) and extracted from the FERC Visual FoxPro and XBRL. See our pudl.extract.ferc1.TABLE_NAME_MAP_FERC1 for links to the raw tables.

The raw version of this table is more like a digitized PDF than an actual data table. The rows contain lots of information in addition to what the columns might suggest. For instance, a single column may contain header rows, note rows, and total rows. This extraneous information is useful, but it prevents proper analysis when mixed in with the rest of the values data in the column. We employ a couple of data transformations to extract these rows from the data and preserve some of the information they contain (fuel type, plant type, FERC license, or general notes about the plant) in separate columns. Browse or query this table in Datasette.
