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 the 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 consumption 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 data 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 generator 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 (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 was collected on Schedules 8A – 8F of 

the Form 923 and includes by-product disposition, financial 

information, NOX 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2008, the EIA-923 superseded the EIA-906, EIA-920, FERC 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 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:

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.

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.
