Alpaugh BESS: FAQ

- Who owns Alpaugh BESS?

- Is this the same as Alpaugh BESS 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 BESS LLC" usually means this site.
