SMT Energy has energized its first standalone battery energy storage system (BESS) within the City of Dallas, marking a significant milestone for urban energy infrastructure in Texas. The new project, named SMT Dallas, features a 10 MW / 15 MWh capacity and is strategically located in Oncor Electric Delivery Company’s service territory.
This facility represents the city’s first operational standalone BESS and adds a critical resource to the Electric Reliability Council of Texas (ERCOT) grid. “This project reflects our commitment to developing fast, flexible storage assets built to support ERCOT’s growing demand needs,” said Miguel Garcia of SMT Energy. The fully merchant project begins operations this July.
Construction was managed under a full-wrap EPC contract by Irby Construction, with FlexGen supplying the battery enclosures, power conversion systems, and its HybridOS energy management software. FlexGen’s Executive VP, Jason Abiecunas, highlighted the urgency of such projects: “ERCOT’s energy demand growth — driven by data centers and electrification — requires fast, reliable storage solutions. SMT Dallas delivers exactly that.”
The collaboration among SMT, Irby, and FlexGen underscores the importance of lean partnerships and rapid deployment in the merchant energy market. SMT Dallas joins SMT’s expanding portfolio across ERCOT, which now exceeds 500 MWh of battery assets.
With grid resilience and renewable integration top of mind, this project positions Dallas as a front-runner in urban energy storage innovation.
