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

EIA-860M names City of Seattle - (WA) 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 Newhalem LLC?

Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — City of Seattle - (WA) 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 "Newhalem LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.

Is Newhalem still running?

EIA-860M files it as "Out of service and NOT expected to return to service in next calendar year" for 2026-07. Statuses change monthly, and this page follows the monthly release.
