Gambit Energy Storage - Angleton Storage is a 100 MW battery energy storage system (BESS) located in Brazoria County, Texas. The plant began operating in 2021 and is owned and operated by Gambit Energy Storage LLC. It is interconnected to the Electric Reliability Council of Texas (ERCOT) grid, within the Texas Reliability Entity (TRE) NERC region. The facility utilizes lithium-ion batteries (LIB) and has a total storage capacity of 200 MWh, providing a duration of 2 hours at full output.
The Angleton Storage facility is ranked as the 211th largest power plant in Texas out of 224, and 494th nationally out of 514. The plant consists of a single generator and uses "MWH" as its primary fuel, indicating that it draws power from the grid to charge its batteries.

Capacity Factor
Positive values indicate net discharge (generation exceeds station load). Negative values indicate net charging. Pure battery storage plants are typically net negative due to round-trip efficiency losses.

No wholesale contracts disclosed in FERC EQR for this plant.
FERC EQR captures bilateral wholesale energy + capacity contracts ≥$1M/yr filed quarterly by jurisdictional sellers — covers renewable PPAs, thermal energy sales agreements, capacity contracts, and tolling agreements alike. Many plants don't appear: regulated-utility output flows to ratepayers via cost-of-service rather than bilateral contracts; small projects fall below the filing threshold; tax-equity-financed renewables route offtake to investors not utilities; merchant plants sell into ISO clearing markets without bilateral contracts. News-extracted buyer facts (below) may surface contracts disclosed only through announcements.
