Riverside Energy Center: FAQ

Where is Riverside Energy Center?
In Rock 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.
How big is Riverside Energy Center?
675 MW of nameplate capacity across 3 units, as of the EIA-860M release for 2026-07.
Who owns Riverside Energy Center?
EIA-860M names Wisconsin Power & Light Co 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 Riverside Energy Center LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Wisconsin Power & Light Co 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 "Riverside Energy Center LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
Is Riverside Energy Center still running?
