Gridstor acquires 900MWh Balanced Rock Power US storage project

March 12, 2024

Utility-scale battery energy storage system developer Gridstor has acquired a battery storage project – with a capacity of up to 450 MW / 900 MWh – in Galveston County, Texas from Balanced Rock Power.

The Evelyn Battery Energy Storage project, which is slated to begin construction in the summer of 2024, has an anticipated on-line date of spring 2025.

Engineering and procurement are underway with suppliers and contractors – the project is expected to employ 100 full-time, skilled tradespeople and apprentices during construction.

The project will be built near the existing Hidden Lakes substation owned by Texas New Mexico Power (TNMP). The site of the project is close to Houston, “which suffers from congestion issues – the inability to deliver low-cost energy due to insufficient capacity”, a statement said.

The statement added that the project “is scheduled to go online at a critical time for Texas”. The Electric Reliability Council of Texas (ERCOT) recently forecasted that summer peak power demand in the state will increase by another 5,000 MW by the end of the decade, with the potential for 16,000 MW of new peak demand during winter extreme weather.

“Battery storage is a scalable and near-term solution to powering historic load growth in Texas,” said Chris Taylor, CEO of GridStor. “Every day, batteries are consistently providing energy to stabilize the power system and meet hours of greatest demand in the state. The rapid deployment of battery energy storage is strengthening the Texas grid to support the growing needs of its residents and businesses today while new power sources and transmission infrastructure are built over the longer term. The quality site selection and early development completed by Balanced Rock Power position this project to contribute substantially to electric reliability in this rapidly growing load area in Texas.”

John Knight, CEO of Balanced Rock Power, added: “We are committed to driving the adoption of clean energy across the United States. Together with GridStor, we’re building clean, reliable and affordable energy solutions today for a promising tomorrow.”
