Utility-scale battery energy storage (BESS) across the United States — power, energy, operator, status and year online, with a public source on every row. Built from the federal EIA-860M generator inventory and re-ingested every month.
Every column we publish: operator, city, capacity (MW/MWh), status, year online and a public source on each row. Opens straight in Excel or Sheets. No card, no call.
One email with the file. No list, no drip sequence — see our privacy policy.
Not a headline count — the row-level detail you would otherwise assemble by hand from EIA spreadsheets and press releases.
Nameplate power in MW and, where the operator reports it, energy capacity in MWh — the pair that tells you whether a site is a frequency-response asset or a four-hour shifting asset.
The entity EIA has on file for the plant, normalized so a portfolio reads as one operator instead of six spellings.
Operating, under construction, or planned, with a target year — so you can separate today's fleet from the pipeline.
City, state and coordinates, plus the ISO/RTO the site sits inside (ERCOT, CAISO, PJM, MISO, SPP, NYISO, ISO-NE) on the map.
Battery storage is not spread evenly — a handful of markets carry most of the megawatts. Jump straight into any state's full project list.
Reading the live dataset.
Battery records are ingested from EIA-860M, the U.S. Energy Information Administration's monthly generator inventory, covering utility-scale plants of 1 MW or more that report to the federal government. The ingest runs after each monthly release; the change log records every project added, removed, or moved between statuses.
Because EIA-860M is a U.S. government work in the public domain, these records carry no upstream redistribution restriction — which is usually the sticking point when a third-party market layer goes into a customer-facing product. It is not one here. The methodology covers definitions, normalization, and what the federal inventory does not include (behind-the-meter and small commercial systems below the 1 MW reporting threshold).
The sample above is 100 rows. The full dataset is every tracked battery and data center project as an Excel hunting list, CSV and GeoJSON — with a row-level change log each month if you subscribe.
