The Electric Reliability Council of Texas (ERCOT) has projected a significant increase in the state’s peak load by 2030 due to the rapid growth in power demand from large industrial customers.

Currently, more than 8GW of battery energy storage has already been implemented on the ERCOT power system, indicating a growing need for reliable energy storage solutions in the region.

GridStor CEO Chris Taylor said: “Battery storage is the fastest, scalable solution to provide reliability in the near-term to the Texas power system and its largest industries.

“Batteries provide energy that stabilises the ERCOT electric grid and supplies its hours of greatest demand every day. Our acquisition demonstrates GridStor’s commitment to roll up our sleeves and build facilities that help Texas sustain its historic economic expansion.”

The project, located in Hidalgo County, Texas, is expected to be operational by mid-2026.

Once in operation, the project aims to support economic growth by enhancing power supply reliability for critical industry sectors along the Gulf Coast.

Balanced Rock Power CEO John Knight said: “BRP is proud to continue supporting GridStor in their efforts to support industrial expansion with utility-scale battery storage.

“Together with GridStor, we are building reliable and affordable energy solutions today for a powerful tomorrow.”

This acquisition marks GridStor’s fourth in the past year and its second transaction with Balanced Rock Power.

GridStor’s initial acquisition from BRP, the Hidden Lakes project, is currently under construction and is expected to be operational this summer.

The company is supported by Goldman Sachs Asset Management.

Last month, GridStor acquired a 200MW/800MWh battery storage project in Oklahoma from Black Mountain Energy Storage (BMES).

To be developed in two phases, the project is expected to address the urgent need for new power resources identified by the Southwest Power Pool (SPP).
