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 description, specific file location(s), and, where appropriate, an explanation 

of codes.

• GeneratorYyy – Contains generator-level data for the surveyed generators, split into three tabs. The 

"Exist" tab includes those generators which are currently 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 cancelled 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 generators surveyed in all available years. 

• UtilityYyy - Contains utility-level data for the plants 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-owned by their operator).

• MultiFuelYyy – Contains data on fuel-switching and the 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 desulfurization (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 for the surveyed generators. The "Boiler" 

tab collects boiler data as collected on Schedule 6, Parts B, and C of the Form EIA-860; "Control" tab 

contains emission data as collected 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 data as collected on Schedule 6, Part G; and the 

"StackFlue" tab collects stack and flue data as collected on Schedule 6, Part I.
