Fillmore County Solar Project: FAQ

Where is Fillmore County Solar Project?
In Fillmore 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.

45 MW of nameplate capacity across 1 unit, as of the EIA-860M release for 2026-07.
Who owns Fillmore County Solar Project?
EIA-860M names Geronimo Power 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 Fillmore County Solar Project LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Geronimo Power 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 "Fillmore County Solar Project LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
