1 GW of nameplate capacity across 2 units, as of the EIA-860M release for 2026-07.

EIA-860M names Hallador Power Company, LLC as the reporting entity. That is the operator of record on the survey, which is not always the ultimate owner.

Is this the same as Merom LLC?

Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Hallador Power Company, LLC here — not the project company that holds the asset. Project companies are commonly registered as an LLC carrying the plant's name, so a search for "Merom LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.

Is Merom still running?

EIA-860M files it as "Operating" for 2026-07. Statuses change monthly, and this page follows the monthly release.
