How big is Silas Ray?

143 MW of nameplate capacity across 8 units, as of the EIA-860M release for 2026-07.

EIA-860M names Brownsville Public Utilities Board 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 Silas Ray LLC?

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

Is Silas Ray still running?

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