Axial Basin Solar: FAQ
- Where is Axial Basin Solar?
- In Moffat 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 Axial Basin Solar?
- 145 MW of nameplate capacity across 1 unit, as of the EIA-860M release for 2026-07.
- Who owns Axial Basin 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 Axial Basin 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 "Axial Basin Solar LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
- Is Axial Basin Solar still running?
