AI generated summary
SMT Energy, in collaboration with CenterPoint Energy and construction firm Irby, has commenced the development of the SMT Houston IV battery energy storage system (BESS) in Texas. This facility will feature a capacity of 160MW/320MWh and is strategically located within the Electric Reliability Council of Texas (ERCOT) market, with an expected completion date in early July. Irby is responsible for the engineering, procurement, and construction aspects of the project, while SMT owns and develops it, and CenterPoint serves as the interconnecting utility.
The SMT Houston IV BESS aims to enhance ERCOT's ancillary services market by providing grid-balancing services and addressing load volatility and renewable energy intermittency. CenterPoint's SVP, Tony Gardner, emphasized the project's contribution to building a more resilient and reliable grid. SMT has secured $135 million in funding for this project, with significant financial backing from Macquarie Group and KeyBanc Capital Markets. Following the completion of SMT Houston IV, SMT will operate a total of eighteen utility-scale BESS assets, with plans for a 2GWh pipeline of additional projects by 2030.
