The Form EIA-923 preliminary 2011 data are published in spreadsheet format. Included are Monthly Generation and Fuel Consumption; Fuel Stocks; Boiler Fuel Data; Generator Data; and Fuel Receipts and Cost Data. The Boiler Fuel Data and Generator Level Data are collected on Schedules 3A and 5A of the Form EIA-923. The Fuel Receipts and Cost Data are collected on Schedule 2 of the Form EIA-923.

Final 2010 data have been revised! Included are the Generation Data: Fuel Consumption, Receipts and Stocks Data; the Nonutility Source and Disposition Data; and the Environmental Data. Net generation data were revised on November 29, 2011.

Form EIA-906, EIA-920, and EIA-923 Data

The EIA-906, EIA-920, EIA-923 and predecessor forms provide monthly and annual data on generation and fuel consumption at the power plant and prime mover levels. A subset of plants, steam-electric plants 10 MW and above, also provides boiler level and generator level data. Data for utility plants are available from 1970, and for nonutility plants from 1999. Beginning with January 2004 data collection, the EIA-920 was used to collect data from the combined heat and power plant (cogeneration) segment of the nonutility sector; also as of 2004, nonutilities filed the annual data for nonutility source and disposition of electricity. Beginning in 2007, environmental data were collected on Schedules 8A – 8F of the Form 923 and includes by-product disposition, financial information, NO_X control operations, cooling system operations and FGP and FGD unit operations. Beginning in 2008, the EIA-923 superseded the EIA-906, EIA-920, FERC 423, and the EIA-423. Schedule 2 of the EIA-923 collects the plant level fuel receipts and cost data previously collected on the FERC and EIA Forms 423. Data for fuel receipts and costs are published at http://www.eia.gov/cneaf/electricity/page/eia423.html.

Power plant data prior to 2001 are published as data (.DBF) files, with separate files for utility and nonutility plants. For 2001 data and subsequent years, the data are in Excel spreadsheet files that include data for all plants and make other changes to the presentation of the data.

Note that beginning with January 2001, the data for combined heat and power plants (i.e., the plants that provide data on the EIA-920 form) will only be posted in the combined Excel file.

The links will allow you to download the current Excel files, and will take you to the locations from which you can download the DBF-format utility and nonutility files for 2000 and earlier. The "Data Notes from EIA" link will take you to information on changes to the data and other points of interest to users.

The Form EIA 906/920 data for 2004-2006 have been updated.

A new method of allocating fuel consumption between electric power generation and useful thermal output (UTO) was implemented for 2004-2008. This new methodology proportionally distributes a combined heat and power (CHP) plant’s losses between the two output products (electric power and UTO). In the historical data, UTO was consistently assumed to be 80 percent efficient and all other losses at the plant were allocated to electric power. This change results in the fuel for electric power to be lower, while the fuel for UTO is higher than the prior set of data as both are given the same efficiency. This results in the appearance of an increase in efficiency of production of electric power between 2003 and 2004. The same methodology is applied to final 2007 and preliminary 2008 data. More information about the methodology can be found in the Appendix C, Technical Notes, to the Electric Power Monthly at:

Combined (Utility, Non-Utility, and Combined Heat & Power Plant) Data in Excel Format

EIA is now using an Excel file for the posting of EIA-906, EIA-920, and EIA-923 data. This single Excel file includes the data for utilities and non-utilities.
