In La Crosse 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 Greenfield?

3 MW of nameplate capacity across 1 unit, as of the EIA-860M release for 2026-07.

EIA-860M names OneEnergy, Inc. 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 Greenfield LLC?

Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — OneEnergy, Inc. 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 "Greenfield LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.

Is Greenfield still running?

EIA-860M files it as "Operating" for 2026-07. Statuses change monthly, and this page follows the monthly release.
