Dolores Canyon Solar: FAQ

Where is Dolores Canyon Solar?
In Dolores County, Colorado (CO). 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 Dolores Canyon Solar?
110 MW of nameplate capacity across 1 unit, as of the EIA-860M release for 2026-07.
Who owns Dolores Canyon Solar?
EIA-860M names Tri-State G & T Assn, 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 Dolores Canyon Solar LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Tri-State G & T Assn, 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 "Dolores Canyon Solar LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
Is Dolores Canyon Solar still running?
EIA-860M files it as "Operating" for 2026-07. Statuses change monthly, and this page follows the monthly release.
