Twin Falls Hydro: FAQ
- Where is Twin Falls Hydro?
- In King 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 Twin Falls Hydro?
- 24 MW of nameplate capacity across 2 units, as of the EIA-860M release for 2026-07.
- Who owns Twin Falls Hydro?
- EIA-860M names Central Rivers Power US, 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 Twin Falls Hydro LLC?
- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Central Rivers Power US, 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 "Twin Falls Hydro LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
