GridStor, a developer and operator of utility-scale battery energy storage systems, announced it has entered into a tolling agreement with a Fortune 500 company for the Gunnar Reliability Project.
The 150-megawatt (MW), 300-megawatt-hour (MWh) facility will be based in Hidalgo County, Texas, with construction already underway. It is expected to commence operations by the end of 2026.
During the construction phase alone, GridStor anticipates it will create over 100 jobs, including positions for skilled tradespersons and apprentices.
The Electric Reliability Council of Texas (ERCOT) forecasts a more than 50% increase in Texas’ peak load by 2030, largely due to industrial customers. Over 12,000 MW of battery energy storage has been deployed in ERCOT’s territory to date.
The Gunnar Reliability Project will bolster the Lower Rio Grande Valley region of the ERCOT system, generating enough electricity to power 95,000 average Texas homes.
“At a time of rapidly increasing power demand, battery energy storage helps ensure affordable, reliable power to households and Lower Rio Grande Valley businesses,” said Chris Taylor, CEO of GridStor, in a statement. “We are proud to increase our commitment to building battery storage facilities that help Texas sustain its historic economic expansion and deliver cost-effective power.”
The project represents GridStor’s second operating battery storage site in Texas, following its 220 MW facility, the Hidden Lakes Reliability Project, that began operating earlier this year in Galveston County.
