How big is Agua Fria?

738 MW of nameplate capacity across 10 units, as of the EIA-860M release for 2026-07.

EIA-860M names Salt River Project 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 Agua Fria LLC?

Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Salt River Project 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 "Agua Fria LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.

Is Agua Fria still running?

EIA-860M files it as "Operating" for 2026-07. Statuses change monthly, and this page follows the monthly release.
