Martin Lake: FAQ

Where is Martin Lake?
In Rusk County, Texas (TX). 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 Martin Lake?
2 GW of nameplate capacity across 3 units, as of the EIA-860M release for 2026-07.
Who owns Martin Lake?
EIA-860M names Luminant Generation Company LLC 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 Martin Lake LLC?
Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Luminant Generation Company LLC 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 "Martin Lake LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
Is Martin Lake still running?
EIA-860M files it as "Operating" for 2026-07. Statuses change monthly, and this page follows the monthly release.
