Ryan: FAQ

Where is Ryan?
In Cascade County, Montana (MT). 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 Ryan?
55 MW of nameplate capacity across 6 units, as of the EIA-860M release for 2026-07.
Who owns Ryan?
EIA-860M names NorthWestern Energy (MT Hydro) 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 Ryan LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — NorthWestern Energy (MT Hydro) 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 "Ryan LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
Is Ryan still running?
EIA-860M files it as "Operating" for 2026-07. Statuses change monthly, and this page follows the monthly release.
