Madelia: FAQ

Where is Madelia?
In WATONWAN County, Minnesota (MN). 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 Madelia?
12 MW of nameplate capacity across 5 units, as of the EIA-860M release for 2026-07.
Who owns Madelia?
EIA-860M names City of Madelia - (MN) 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 Madelia LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — City of Madelia - (MN) 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 "Madelia LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
