Flambeau Hydroelectric Station: FAQ

Where is Flambeau Hydroelectric Station?
In Rusk County, Wisconsin (WI). The map on this page is placed at the coordinates EIA files for the plant, which locate the site rather than any individual unit.

Who owns Flambeau Hydroelectric Station?

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