Where is Alta Wind XI?

Who owns Alta Wind XI?

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