LEPA Unit No. 1: FAQ

Where is LEPA Unit No. 1?
In St Mary County, Louisiana (LA). 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 LEPA Unit No. 1?
74 MW of nameplate capacity across 2 units, as of the EIA-860M release for 2026-07.
Who owns LEPA Unit No. 1?
EIA-860M names Louisiana Energy & Power Authority 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 LEPA Unit No. 1 LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Louisiana Energy & Power Authority 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 "LEPA Unit No. 1 LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
Is LEPA Unit No. 1 still running?
EIA-860M files it as "Operating" for 2026-07. Statuses change monthly, and this page follows the monthly release.
