Query verified U.S. generator-level operating, planned, retired, or canceled power capacity from EIA-860M.
Use this for capacity questions by state/jurisdiction, county FIPS,
source-reported balancing authority code, fuel, prime mover, technology,
lifecycle, or year. Pass filters inside the `params` object. The
operating/planned/retired/canceled selector is `lifecycle` (e.g.
`lifecycle: "operating"`, the default) — there is no `status` or `status_group`
parameter. Returns JSON aggregates with
citations and optional generator-level records when `include_records` is true.
Does not determine electricity supplied, generation MWh, real-time dispatch,
capacity factor, battery storage throughput/duration, demand/load, prices,
data-center load, or transmission deliverability. For capacity REQUESTED in an ISO
interconnection queue (projects pending interconnection, not yet built), use
query_power_interconnection_queue_v1.
