Alpaugh 50: FAQ

Where is Alpaugh 50?
In Tulare 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 Alpaugh 50?
50 MW of nameplate capacity across 1 unit, as of the EIA-860M release for 2026-07.
Who owns Alpaugh 50?
EIA-860M names RWE Clean Energy 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 Alpaugh 50 LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — RWE Clean Energy 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 "Alpaugh 50 LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
Is Alpaugh 50 still running?
