Overview

Balancing_Authority. The 2012 file maps utilities to balancing authorities instead, and carries utility_number where later years do not. event_time is 1 January of the report year. release is final or early_release: EIA posts an early release of a year in August and replaces it with the final file in the autumn, and the mirror keeps the newest row per key. A key cell EIA leaves blank is '' or 0, and duplicate_index numbers rows that still share a key, in workbook order.

Query contract

Preserve one canonical row per (event_time, ba_code, state, utility_number, duplicate_index) before aggregating.

Analysis rules

Group only after preserving the declared grain: event_time, ba_code, state, utility_number, duplicate_index.

Dataset	Description
Advanced MetersEIA · annual (report year)	EIA-861 advanced metering: AMR, AMI and other meter counts, AMI energy served and customer access, by utility and customer class. Advanced_Meters, one row per utility, state, balancing authority and customer class. customer_class is residential, commercial, industrial, transportation (direct_connected in the distributed generation tables) or EIA's own total, so summing classes without excluding total counts everything twice. event_time is 1 January of the report year. release is final or early_release: EIA posts an early release of a year in August and replaces it with the final file in the autumn, and the mirror keeps the newest row per key. A key cell EIA leaves blank is '' or 0, and duplicate_index numbers rows that still share a key, in workbook order.
Distribution SystemsEIA · annual (report year)	EIA-861 distribution systems: distribution circuit counts and circuits with voltage optimization, by utility. Distribution_Systems, 2013 on. event_time is 1 January of the report year. release is final or early_release: EIA posts an early release of a year in August and replaces it with the final file in the autumn, and the mirror keeps the newest row per key. A key cell EIA leaves blank is '' or 0, and duplicate_index numbers rows that still share a key, in workbook order.
Operating GeneratorsEIA · monthly + annual (snapshot)	A generator-level inventory of every operable utility-scale electric generator in the United States, drawn from EIA Form 860. Each record describes one generating unit, including its nameplate capacity, technology and prime mover, primary energy source, operating status, owner or operator, balancing authority, and the latitude and longitude of its plant. It is the standard reference for understanding what physical generation exists on the grid, where it sits, and how it is fueled. Annual final filings give the authoritative year-end picture, while the monthly EIA-860M updates track newly proposed, added, and retired units between annual releases, making it useful for tracking the fleet's evolving capacity mix and the buildout of new resources.
Solar GeneratorsEIA · monthly + annual (snapshot)	This is the utility-scale solar slice of the EIA-860 generator inventory, listing every operating solar generating unit along with its plant, location, owner, nameplate and net capacity, and in-service dates. It adds solar-specific attributes such as panel tracking type (fixed, single-axis, or dual-axis) and tilt angle. Researchers and analysts can use it to map where solar capacity sits on the grid, gauge how design choices shape generation profiles, and track the buildout of utility-scale solar over time. The source is the EIA-860 annual survey, with the inventory refreshed monthly between full annual snapshots.
