Return to SearchIndividual fuel deliveries to power plants, organized by fuel type and supplier.
- Most-recent data:
2025
- Processing:
Data has been cleaned and organized into well-modeled tables that serve as building blocks for downstream wide tables and analyses.
- Source:
EIA Form 923 -- Power Plant Operations Report (Schedule 2 - Part A)
- Primary key:
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.
Usage Warnings
Date column arbitrarily uses the first of the month.
Some values have been redacted.
Time of fuel deliveries is not necessarily connected with time of fuel consumption.
Additional Details
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.
Columns
The unique six-digit facility identification number, also called an ORISPL, assigned by the Energy Information Administration.
Date reported.
Purchase type under which receipts occurred in the reporting month. C: Contract, NC: New Contract, S: Spot Purchase, T: Tolling Agreement.
Date contract expires.Format: MMYY.
A 2-3 letter code indicating the energy source (e.g. fuel type) associated with the record.
Simplified fuel type code used in PUDL
Fuel groups used in the Electric Power Monthly
Dynamically assigned PUDL mine identifier.
Company that sold the fuel to the plant or, in the case of Natural Gas, pipeline owner.
Quantity of fuel received in tons, barrel, or Mcf.
Heat content of the fuel in millions of Btus per physical unit.
Sulfur content percentage by weight to the nearest 0.01 percent.
Ash content percentage by weight to the nearest 0.1 percent.
Mercury content in parts per million (ppm) to the nearest 0.001 ppm.
Average fuel cost per MMBTU of heat content in nominal USD.
Transportation mode for the longest distance transported.
Transportation mode for the second longest distance transported.
Contract type for natural gas transportation service.
Contract type for natural gas delivery service:
For coal only: the moisture content of the fuel in terms of moisture percentage by weight. Reported to the nearest 0.01 percent.
For coal only: the chlorine content in parts per million (ppm) to the nearest 0.001 ppm. If lab tests of the coal do not include the chlorine content, this field contains the amount specified in the contract with the supplier.
Maturity of the source data published by EIA that is reflected in this record. EIA releases data incrementally over time, including monthly updates, annual year-to-date updates, provisional early releases of annual data, and final annual release data that is not expected to change further. Records sourced from multiple upstream EIA datasets may have no well defined data maturity. Records whose values have been inferred within PUDL will also have no data maturity.
