Marble Falls: FAQ
- Where is Marble Falls?
- In Burnet 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 Marble Falls?
- 40 MW of nameplate capacity across 2 units, as of the EIA-860M release for 2026-07.
- Who owns Marble Falls?
- EIA-860M names Lower Colorado River 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 Marble Falls LLC?
- Probably, but EIA-860M does not say. The survey records a plant name and a reporting entity — Lower Colorado River 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 "Marble Falls LLC" usually means this site. This page shows only what EIA files, and does not assert a corporate structure it cannot see.
- Is Marble Falls still running?
- EIA-860M files it as "Operating" for 2026-07. Statuses change monthly, and this page follows the monthly release.
