ELECTRICITY DETAILED SURVEY DATA FILES

Electric power sales, revenue, and energy efficiency Form EIA-861 detailed data files
                                         

Release Date for 2013: February 19, 2015
Next Release date: October 2015

Annual data for 2013 re-released:  February 27, 2015 (Revision\Correction)

The Form EIA-861 and Form EIA-861S (Short Form) data files include information such as peak load, generation, electric purchases, sales, revenues, customer counts and demand-side management programs, green pricing and net metering programs, and distributed generation capacity.

The EIA-861S was created in 2012 in an effort to reduce respondent burden and to increase EIA's processing efficiency. Approximately 1,100 utilities completed this form in lieu of the 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 "Retail Sales." Advanced metering data and time-of-use data are collected on both Form EIA-861 and Form EIA-861S.

In 2012, the data files were renamed to help users find the data. Data files prior to 2012 retained their original names, and, in the description below, the prior names are referred to as "Formerly."

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, were the number of distribution circuits (Distribution Systems) and SAIDI* and SAIFI** (Reliability) data.

  • Advanced Meters – This file, compiled from data collected on both Forms EIA-861 and EIA-861S, contains information on Automated Meter Readings (AMR) and Advanced Metering Infrastructure (AMI).  (Formerly File 8)
  • Balancing Authority – This file, compiled from data collected on both Forms EIA-861 and EIA-861S, contains information on Balancing Authorities. (Formerly File 1_cao)
  • 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.
  • Distributed Generation – This file, compiled from data collected on Form EIA-861 only, contains information on utility or customer-owned distributed and dispersed generation such as the number, capacity, and types of generators.  Capacities by photovoltaic and storage generation types were added in 2010. (Formerly File 6)
  • 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.  (Formerly File 7)
  • 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, and/or other.
  • Operational Data – 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, including power marketers and federal power marketing administrations.  (Formerly File 1)
  • Reliability (2013 forward) – This file, compiled from data collected on Form EIA-861 only, contains SAIDI and SAIFI data.
  • Retail Sales – 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.  (Formerly File 2)
  • Service Territory – 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 respondent has equipment for the distribution of electricity to ultimate consumers. (Formerly File 4)
  • Short Form (2012 forward) – This file, compiled from data collected on the Form EIA-861S in aggregate, contains information on retail revenue, sales, and customer counts by state.
  • Utility Data (2007 forward) – This file, compiled from data collected on Form EIA-861 only, contains information on the types of activities each utility engages in, the NERC regions of operation, whether the utility generates power, whether  it operates alternative-fueled vehicles, and, beginning in 2010, the ISO or RTO region in which the entity conducts operations. (Formerly File 1_a)
  • Demand-Side Management (discontinued after 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.  (Formerly File 3)
  • Green Pricing (discontinued after 2012) – This file, compiled from data collected on Form EIA-861 only, contains number of customers, sales, and revenue, by sector and state.  (Formerly File 5)

Note: : All sales data, including energy efficiency savings, are in megawatthours. Peak and peak reduction data are in megawatts for 2001 forward and kilowatts for previous years. Revenue and expenditure data are in thousand-dollar units.
