Vancourt Solar Interconnections: FAQ

Where is Vancourt Solar Interconnections?

Who owns Vancourt Solar Interconnections?
EIA-860M names Rayos del Sol Solar Project, 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 Vancourt Solar Interconnections LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Rayos del Sol Solar Project, 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 "Vancourt Solar Interconnections LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
