Fairhaven Power: FAQ

Where is Fairhaven Power?
In Humboldt County, California (CA). The map on this page is placed at the coordinates EIA files for the plant, which locate the site rather than any individual unit.
How big is Fairhaven Power?
19 MW of nameplate capacity across 1 unit, as of the EIA-860M release for 2026-07.
Who owns Fairhaven Power?
EIA-860M names DG Fairhaven Power 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 Fairhaven Power LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — DG Fairhaven Power 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 "Fairhaven Power LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
Is Fairhaven Power 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.
