Annual Electric Power Industry Report, Form EIA-861 detailed data files

Form EIA-861 and Form EIA-861S (short form) data files include information such as peak load, generation, electric purchases, sales, revenues, customer counts, energy efficiency, demand response, net metering programs, and distributed generation capacity.

EIA created the EIA-861S in 2012 in an effort to reduce respondent burden and to increase EIA's processing efficiency. About 1,100 utilities completed this form in lieu of Form EIA-861. The short form has fewer questions and collects retail sales data as an aggregate and not by customer sector. EIA has estimated the customer sector breakdown for this data and has included it in the file called Sales to Ultimate Customers. Advanced metering data and time-of-use data are collected on both Form EIA-861 and Form EIA-861S.

Green pricing and demand-side management data were no longer collected after 2012. In 2013, demand-side management data started being collected as energy efficiency and demand response data. Also new in 2013, the number of distribution circuits (Distribution Systems) and System Average Interruption Duration Index (SAIDI) and System Average Interruption Frequency Index (SAIFI) (Reliability) data were introduced.

Files were reformatted for the years 1990–2011. No data were changed or updated. The files were reformatted for ease of use and to match the format and titles of the current files.

  • Frame (2016 forward) — This file, compiled from data collected on both Form EIA-861 and Form EIA-861S, contains a complete list of all respondents from both forms and a list of each file they are in.
  • Advanced Meters (2007 forward) — This file, compiled from data collected on both Form EIA-861 and Form EIA-861S, contains information on Automated Meter Readings (AMR) and Advanced Metering Infrastructure (AMI).
  • Balancing Authority (2012 forward) — This file contains the list of Balancing Authorities and the states they operate in for Form EIA-861 and Form EIA-861S.
  • Demand Response (2013 forward) — This file, compiled from data collected on Form EIA-861 only, contains the number of customers enrolled, energy savings, potential and actual peak savings, and associated costs.
  • Distribution Systems (2013 forward) — This file, compiled from data collected on Form EIA-861 only, contains the number of distribution circuits and circuits with voltage optimization.
  • Dynamic Pricing (2013 forward) — This file, compiled from data collected on Form EIA-861 only, contains the number of customers enrolled in various programs, i.e., time of use, real time, variable peak and critical peak pricing, and critical peak rebate programs.
  • Energy Efficiency (2013 forward) — This file, compiled from data collected on Form EIA-861 only, contains incremental and life cycle data on energy savings, peak demand savings, weighted average life, and associated costs.
  • Mergers (2007 forward) — This file, compiled from data collected on Form EIA-861 only, contains information on mergers and acquisitions.
  • Net Metering (2007 forward) — This file, compiled from data collected on Form EIA-861 only, contains number of customers and displaced energy, by sector and state. For 2010 forward, it contains capacity, customer count, and energy sold back (an optional question on the survey) by sector and state and by technology type, i.e., photovoltaic, wind, or other.
  • Non Net Metering Distributed (2010 forward) — This file, compiled from data collected on Form EIA-861 only, contains information on utility- or customer-owned distributed generators such as the number, capacity, and technology type of generators. Capacities by photovoltaic and storage generation types were added in 2010, fuel cells were added in 2016. Starting in 2016, this data is now collected at the sector level.
  • Operational Data (1990 forward) — This file, compiled from data collected on Form EIA-861 only, contains aggregate operational data for the source and disposition of energy and revenue information from each electric utility in the country.
  • Reliability (2013 forward) — This file, compiled from data collected on Form EIA-861 only, contains SAIDI and SAIFI data.
  • Sales to Ultimate Customers (1990 forward) — This file, compiled from data collected on the Form EIA-861 and an estimate from Form EIA-861S for data by customer sector, contains information on retail revenue, sales, and customer counts by state, balancing authority, and class of service (including the transportation sector which was added in 2003) for each electric distribution utility or energy service provider.
  • Sales to Ultimate Customers, Customer Sited (2002 forward) — This file, compiled from data collected on the Form EIA-923 only, contains information on retail revenue, sales, and customer counts by state and balancing authority. This includes retail sales from any units located at a customer site.
  • Service Territory (2001 forward) — This file, compiled from data collected on the Form EIA-861 and Form 861S, contains the names of the counties, by state, in which the utility has equipment for the distribution of electricity to ultimate consumers.
  • Short Form (2012 forward) — This file, compiled from data collected on the Form EIA-861S in aggregate (not by sector), contains information on retail revenue, sales, and customer counts by utility and by state.
  • Utility Data (1990 forward) — This file, compiled from data collected on Form EIA-861 only, contains information on the types of activities each utility engages in, the North American Electric Reliability (NERC) regions of operation, whether the utility generates power, whether it operates alternative-fueled vehicles, and, beginning in 2010, the Independent System Operator (ISO) or Regional Transmission Organization (RTO) region in which the entity conducts operations.
  • Demand-Side Management (2001–2012) — This file, compiled from data collected on both Form EIA-861 and, for time-based rate programs, Form EIA-861S, contains information on electric utility demand-side management programs, including energy efficiency and load management effects and expenditures. Beginning in 2007, it also contains the number of customers in time-based rate programs.
  • Green Pricing (2001–2012) — This file, compiled from data collected on Form EIA-861 only, contains number of customers, sales, and revenue, by sector and state.

Note: All sales data, including energy efficiency savings, are in megawatthours. Peak and peak reduction data are in megawatts. Revenue and expenditure data are in nominal thousand-dollar units.
