Langdon Wind Energy Center: FAQ

Where is Langdon Wind Energy Center?
In Cavalier County, North Dakota (ND). 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 Langdon Wind Energy Center?
41 MW of nameplate capacity across 1 unit, as of the EIA-860M release for 2026-07.
Who owns Langdon Wind Energy Center?
EIA-860M names Otter Tail Power 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 Langdon Wind Energy Center LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Otter Tail Power 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 "Langdon Wind 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 Langdon Wind Energy Center still running?
EIA-860M files it as "Operating" for 2026-07. Statuses change monthly, and this page follows the monthly release.
