Douglas: FAQ
- Where is Douglas?
- In Cochise County, Arizona (AZ). 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 Douglas?
- 26 MW of nameplate capacity across 1 unit, as of the EIA-860M release for 2026-07.
- Who owns Douglas?
- EIA-860M names Arizona Public Service 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 Douglas LLC?
- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Arizona Public Service 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 "Douglas LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
- Is Douglas still running?
- EIA-860M files it as "Operating" for 2026-07. Statuses change monthly, and this page follows the monthly release.
