07.07.2026 - SMT Energy and Axpo have signed a 120 MW, seven-year battery storage swap agreement tied to SMT Energy's Houston IV BESS, a newly operational 160 MW/320 MWh battery energy storage system in the Electric Reliability Council of Texas (ERCOT) market. The agreement supports long-term revenue visibility for Houston IV and highlights SMT Energy's ability to develop, commercialize and operate utility-scale battery storage assets in Texas.
The bespoke agreement provides SMT Energy with predictable, long-term contracted revenue for its Houston IV battery project while supporting SMT Energy's ability to advance additional battery storage assets in Texas.
Luke Tosheff, Origination Director at Axpo in the U.S., said: "Our focus at Axpo is to provide structured products that help developers like SMT Energy navigate market complexity. This seven-year swap is an example of how we can create long-term revenue certainty for battery storage projects. We're proud to support SMT's growth and help bring critical flexibility and reliability to the Texas grid."
Miguel Garcia, Head of Commercial Strategy at SMT Energy, said: "Houston IV represents the type of large-scale, grid-critical battery storage asset SMT Energy was built to deliver. Pairing a 160 MW operating BESS with a seven-year structured swap agreement is an important commercial milestone for SMT Energy and provides durable revenue visibility for the project. Axpo was a constructive partner in tailoring a solution that supports Houston IV and strengthens SMT Energy's ability to advance additional battery storage and power infrastructure assets across Texas."
