Owyhee Dam Power Project: FAQ

Where is Owyhee Dam Power Project?
In Malheur County, Oregon (OR). 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 Owyhee Dam Power Project?
5 MW of nameplate capacity across 1 unit, as of the EIA-860M release for 2026-07.
Who owns Owyhee Dam Power Project?
EIA-860M names Owyhee Irrigation District 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 Owyhee Dam Power Project LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Owyhee Irrigation District 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 "Owyhee Dam Power Project LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
Is Owyhee Dam Power Project still running?
EIA-860M files it as "Operating" for 2026-07. Statuses change monthly, and this page follows the monthly release.
