Hiilangaay Hydro: FAQ

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