How big is O'Brien 1?

5 MW of nameplate capacity across 1 unit, as of the EIA-860M release for 2026-07.

EIA-860M names Generate Capital 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 O'Brien 1 LLC?

Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Generate Capital 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 "O'Brien 1 LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.

Is O'Brien 1 still running?

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