Dave Gates Generating Station: FAQ

Where is Dave Gates Generating Station?

Who owns Dave Gates Generating Station?
EIA-860M names NorthWestern Energy (MT wind/thermal) 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 Dave Gates Generating Station LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — NorthWestern Energy (MT wind/thermal) 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 "Dave Gates Generating Station LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
