Every plant Form EIA-860 lists for the inventory year: where it is, who operates it, which balancing authority it reports to, and whether the atlas publishes it. Published plants report to a frame balancing authority or sit in Washington, Oregon, Idaho or Montana; the rest stay in the table, marked unpublished.
One row per plant as Form EIA-860 identifies it. The table carries no quantity of its own; capacity is on the generator table.

Publisher
Form EIA-860 is EIA's Annual Electric Generator Report. Its page lists releases of two kinds: early release data and final data.www.eia.gov/electricity/data/eia860/ ↗

This atlas
The atlas reads EIA-860 through PUDL, which Catalyst Cooperative publishes as quarterly versioned releases. Each atlas release pins one PUDL version, named under edition; the table changes only when that pin moves. No timed refresh.docs.catalyst.coop/pudl/en/v2026.9.0/data_access.html ↗
