The January 2008 file includes utility and nonutility generation and fuel consumption and stocks data from Schedule 3, 4, and 5 of the new Form EIA-923. It is formatted in the same manner as the EIA-906_920 database.

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

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 level. Data for utility plants is available from 1970, and for non-utility 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 non-utility sector.  Beginning in 2008, the EIA-923 superceded both the EIA-906 and the EIA-920. 

Power plant data prior to 2001 are published as database (.DBF) files, with separate files for utility and non-utility plants. For 2001 data and subsequent years, EIA is publishing the data in an Excel spreadsheet file that includes data for all plants and makes 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 non-utility files for 2000 and earlier. The "Database 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 databases 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 databases. 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) Database 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.
