Stonewall BESS is a 135 MW battery energy storage system located in Stonewall County, Texas. The plant is owned and operated by RIC Development, LLC. It consists of a single generator and utilizes MWH as its primary fuel source, indicating it draws power from the grid to charge its batteries. The facility operates within the Electric Reliability Council of Texas (ERCOT) balancing authority, which falls under the Texas Reliability Entity (TRE) NERC region.
Stonewall BESS is ranked as the 178th largest power plant in Texas out of 224 facilities and 416th nationally out of 514 plants. The plant's capacity contributes to grid stability and reliability within the ERCOT market by providing ancillary services such as frequency regulation and voltage support. As a battery storage facility, its output depends on market conditions and grid needs, charging during periods of low demand and discharging during peak demand or grid emergencies.

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.
