Nooksack Hydro: FAQ

Where is Nooksack Hydro?
In Whatcom County, Washington (WA). 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 Nooksack Hydro?
2 MW of nameplate capacity across 1 unit, as of the EIA-860M release for 2026-07.
Who owns Nooksack Hydro?
EIA-860M names Puget Sound Hydro 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 Nooksack Hydro LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Puget Sound Hydro 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 "Nooksack Hydro LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
Is Nooksack Hydro still running?
EIA-860M files it as "Operating" for 2026-07. Statuses change monthly, and this page follows the monthly release.
