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

Data Released: June 16, 2011 Data for: March 2011 Next Release: Mid-July 2011

The Form EIA-923 preliminary 2010 and 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 th e Form EIA-923. The Fuel Receipts and Cost Data are collected on Schedule 2 of the Form EIA-923.

Final 2009 data have been revised! Revisions in Form EIA923 data associated with three power generating plants in Maine, Ohio, and Texas have resulted in the following changes: Maine, the consumptio n of black liquor was revised at a plant. Ohio, revisions were made to the energy source codes for two boilers at one plant from 'Other' to 'Other Gas.' Texas, generation attributable to black liquor, wood solids, and natural gas was revised at one plant.



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

The EIA-906, EIA-920, EIA-923 and predecessor forms provide monthly and annual dat a on generation and fuel consumption at the power plant and prime mover level. A subset of plants, steam-electric plants 10 MW and above, also provides boiler level and genera tor level data. Data for utility plants are available from 1970, and for nonutility plants from 1999. Beginning with January 2004 data collection, the EIA920 was used to collect data from the combined heat and power plant (cogener ation) segment of the nonutility sector; also as of 2004, no nutilities filed the annual data for nonutility source and disposition of electricity. Beginning in 2007, environmental data was collect ed on Schedules 8A – 8F of the Form 923 and includes by-p roduct disposition, financial information, NOX control op erations, cooling system operations and FGP and FGD uni t operations. Beginning in 2008, the EIA-923 superseded th e EIA-906, EIA-920, FERC 423, and the EIA-423.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 prior to 2010 are published 

### 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: /cneaf/electricity/epm/appenc.pdf

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

EIA is now using an Exce l 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.

.

Power plant data prior to 2001 are published as data (.DBF) files, with separate files for ut ility and nonutilit y 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 Januar y 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 downl oad the current Excel files, and will take you to the locations from which you can download the DBF-format utilit y and nonutility files for 2000 and earlier. The "Dat a Notes from EIA" link will take you to information on changes to the data and other points of interest to users.
