West Valley Solar: FAQ

- 10 MW of nameplate capacity across 2 units, as of the EIA-860M release for 2026-07.
- Who owns West Valley Solar?

- Is this the same as West Valley Solar LLC?
- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — West Valley Solar, 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 "West Valley Solar LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
