How big is Solar Blue?

475 MW of nameplate capacity across 2 units, as of the EIA-860M release for 2026-07.

EIA-860M names Westlands Solar Blue 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 Solar Blue LLC?

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

Is Solar Blue still running?

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