Lime Creek: FAQ

Where is Lime Creek?
In Cerro Gordo County, Iowa (IA). 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 Lime Creek?
90 MW of nameplate capacity across 2 units, as of the EIA-860M release for 2026-07.
Who owns Lime Creek?
EIA-860M names Interstate Power and 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 Lime Creek LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Interstate Power and 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 "Lime Creek LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
Is Lime Creek still running?
EIA-860M files it as "Operating" for 2026-07. Statuses change monthly, and this page follows the monthly release.
