Form EIA-860 Annual Electric Generator Report

The Form EIA-860 is a generator-level survey that collects specific information about existing and planned generators and associated environmental equipment at electric power plants with 1 megawatt or greater of combined nameplate capacity. The survey data are summarized in reports such as the Electric Power Annual. The survey data are also available for download here.

The data are compressed into a self-extracting (.exe) zip folder containing .XLS data files and record layouts. The current file structure (starting with 2009 data) consists of a record layout, 8 data files and a copy of the applicable version of the Form EIA-860 on which the data were collected.

The data folders consist of the following files (substitute the applicable year for "yy" in the file name):

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.

UtilityYyy – Contains utility-level data for the generators surveyed in all available years.

PlantYyy – Contains plant-level data for the generators surveyed in all available years.

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).

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.
