Some values have been redacted.
Contains rows where missing values were imputed.
Additional Details
Respondents are required to report this information to the EIA, but are not required to disclose utility-level data to the public. When a respondent chooses to keep its utility-level data proprietary, it files using EIA utility id 88888. For more details, see EIA-861 Notable Irregularities <eia861-notable-irregularities>.
Rows where data_observed is False were labeled as imputed in the raw EIA data. The EIA documentation does not specify what imputation applies to operational data, only net metering and non net-metering distributed data. Less than 1% of rows are labeled as imputed, all of which occur in 2004 or 2005. Imputed rows make up no more than 25% of the rows for any utility.
Columns
The amount of electricity used by the facility.
The amount of electricity used by the electric utility in its electric and other departments without charge.
Is the value observed (True) or imputed (False).
Entity type of principal owner.
The amount of exchange energy delivered. Does not include power delivered as part of a tolling arrangement.
The amount of exchange energy received. Does not include power received through tolling arrangements.
The amount of electricity furnished by the electric utility without charge, such as to a municipality under a franchise agreement or for street and highway lighting.
NERC region in which the plant is located
Net electricity generation for the specified period in megawatt-hours (MWh).
The net amount of energy exchanged. Net exchange is the difference between the amount of exchange received and the amount of exchange delivered. This entry should not include wholesale energy purchased from or sold to regulated companies or unregulated companies for other systems.
The difference between the amount of energy entering the respondent's system (wheeled received) for transmission through the respondent's system and the amount of energy leaving the respondent's system (wheeled delivered). Wheeled net represents the energy losses on the respondent's system associated with the wheeling of energy for other systems.
Date reported.
MWh of sales to end-use customers in areas where the customer has been given the legal right to select a power supplier other than the traditional, vertically integrated electric utility.
The amount of electricity sold for resale purposes. This entry should include sales for resale to power marketers (reported separately in previous years), full and partial requirements customers, firm power customers and nonfirm customers.
Whether the reported information comes from the short form. In the case of form EIA 861, a shorter version of the form was created in 2012 to reduce respondent burden on smaller utilities and increase our processing efficiency.
Two letter US state abbreviation.
The maximum hourly summer load (for the months of June through September) based on net energy for the system during the reporting year. Net energy for the system is the sum of energy an electric utility needs to satisfy their service area and includes full and partial wholesale requirements customers, and the losses experienced in delivery. The maximum hourly load is determined by the interval in which the 60-minute integrated demand is the greatest.
Sum of all disposition of electricity listed. Includes sales to ultimate customers, sales for resale, energy furnished without charge, energy consumed by respondent without charge and total energy losses.
The total amount of electricity lost from transmission, distribution, and/or unaccounted for. Should be expressed as a positive number.
Sum of all sources of electricity listed. Includes net generation, purchases from electricity suppliers, net exchanges (received - delivered), net wheeled (received - delivered), transmission by others, and losses.
The amount of energy losses associated with the wheeling of electricity provided to the respondent's system by other utilities. Transmission by others, losses should always be a negative value.
The EIA Utility Identification number.
The name of the utility.
The total amount of energy leaving the respondent's system that was transmitted through the respondent's system for delivery to other systems. If wheeling delivered is not precisely known, the value is an estimate based on the respondent's system's known percentage of losses for wheeling transactions.
The total amount of energy entering the respondent's system from other systems for transmission through the respondent's system (wheeling) for delivery to other systems. Does not include energy purchased or exchanged for consumption within the respondent's system, which was wheeled to the respondent by others.
Purchases from electricity suppliers.
The maximum hourly winter load (for the months of January through March) based on net energy for the system during the reporting year. Net energy for the system is the sum of energy an electric utility needs to satisfy their service area and includes full and partial wholesale requirements customers, and the losses experienced in delivery. The maximum hourly load is determined by the interval in which the 60-minute integrated demand is the greatest.
Maturity of the source data published by EIA that is reflected in this record. EIA releases data incrementally over time, including monthly updates, annual year-to-date updates, provisional early releases of annual data, and final annual release data that is not expected to change further. Records sourced from multiple upstream EIA datasets may have no well defined data maturity. Records whose values have been inferred within PUDL will also have no data maturity.
