### OVERVIEW DATA ANALYSIS & PROJECTIONS 

## Form EIA-860 detailed data with previous form data (EIA-860A/860B) Release Date: September 24, 2012 for Final 2011 data Revised: January 9, 2013 Next Release Date: July 2013 

### The survey Form EIA-860 collects generator-level specific information about existing and planned generators and associated environmental equipment at electric power plants with 1 megawatt or greater of combined nameplate capacity. Summary level data can be found in the Electric Power Annual

. Detailed data are compressed (zip) and contain the following files:

• LayoutYyy – Provides a directory of all (published) data elements collected on the Form EIA-860

together with the related descripti on, specific file location(s), and, where appropriate, an explanation of codes. • GeneratorYyy – Contains generator-level data for the survey ed generators, split into three tabs. The

"Exist" tab includes those generators which are curr ently operating, out of service or on standby; the "Prop" tab includes those generators which are planned and not yet in operation; and the "Ret_IP" tab includes those generators which were cance lled prior to completion and operation and retired generators at existing plants (does not include data for retired generators at plants at which all generators have been retired). • PlantYyy- Contains plant-level data for the generat ors surveyed in all available years. • UtilityYyy - Contains utility-level data for the plant s and generators surveyed in the reporting year. • OwnerYyy – Contains owner and/or operator data for generators with shared ownership and

generators that are wholly-owned by an entity other than the operator (generators not appearing in the file are wholly-o wned by their operator). • MultiFuelYyy– Contains data on fuel-switching and t he use of multiple fuels by surveyed

generators, split into three tabs: "Exist," "Prop," and "Ret_IP." See GeneratorsYyy above for a description of the tabs. • InterconnectYyy – Contains interconnection data for the surveyed generators. • EnviroAssocYyy– Contains boiler association data for the environmental equipment data collected

on the Form EIA-860. The "Boiler_Gen" identifies which boilers are associated with each generator; the "Boiler_Cool" tab shows which cooling systems are associated with each boiler; the "Boiler_FGD" tab shows which flue gas desulfu rization (FGD) systems are associated with each boiler; the "Boiler_FGP" tab shows which flue gas particulate (FGP) collectors are associated with each boiler; and the "Boiler_SF" tab shows which stacks and flues are associated with each boiler. • EnviroEquipYyy– Contains environmental equipment data fo r the surveyed generators. The "Boiler"

tab collects boiler data as collected on Schedule 6, Part s B, and C of the Form EIA-860; "Control" tab contains emission data as collect ed on Schedule 6, Parts D and E; the "Cooling" tab collects cooling system data as collected on Schedule 6, Part F; the "FGD" tab collects FGD data as collected on Schedule 6, Part H; the "FGP" tab collects FGP da ta as collected on Schedule 6, Part G; and the "StackFlue" tab collects stack and flue data as collected on Schedule 6, Part I. 

### Superseded Form EIA-860A (Utility) & B (Non-Utility) -- Retired Annual Electric Generator ReportElectric utility generator level data includes information for company, facility, unit type, prime mover, inservice date, energy source, heat content, nameplate capacity, summer and winter capability, etc. 860-A (Utility) Data are compressed into a zip file that expands into xls data files and a txt layout file:

• PLANTYyy - plant-level data • UTILYyy - utility-level data • TYPE3Yyy & TYPE4Yyy- 2 generator files for 1990-1997

or GeneratorOwnershipyyyy, ProposedGe neratorsyyyy, ExistingGeneratorsyyyy - 3 generator files for 1998-2000 • LAYOUT- ASCII layout file 

### 860-B (Non-Utility) Data are compressed into a zip file that expands into xls data files and a txt layout file:

• qfdocket - qualifying data • xdocket - plant-level data • cogen - cogeneration data • nuppfac - non-utility power producer data • fuelquant- fuel quantities • genergy - 2 generator files • generator • noxequip - nox removal data • LAYOUT- ASCII layout file Year format 2011 ZIP 2010 ZIP 2009 ZIP 2008 ZIP 2007 ZIP 2006 ZIP 2005 ZIP 2004 ZIP 2003 ZIP 2002 ZIP 2001 ZIP
