Energy Vault to build 57MW battery storage project in Texas

Energy Vault has announced plans for a 57MW/114MWh battery energy storage system (BESS), named Cross Trails BESS, to be built in Scurry County, Texas. 

Construction is scheduled to begin in Q1 2025, with commercial operations expected by mid-2025. 

Energy Vault will build, own, and operate the project using its X-Vault integration platform, UL9540-certified B-VAULT product, and VaultOS energy management system, offering flexibility for both AC and DC-coupled configurations.

The project aims to boost renewable energy output and enhance grid resilience within the ERCOT region. Energy Vault has also signed a ten-year offtake agreement with Gridmatic, marking ERCOT’s first “physically settled revenue floor contract” for a BESS. Gridmatic’s AI-enabled forecasts will support the agreement, ensuring stable returns and optimized energy delivery.

Energy Vault chair and CEO Robert Piconi emphasized the importance of owning storage infrastructure to enhance shareholder value and meet the rising demand for energy storage solutions. Last month, Energy Vault signed another agreement to deploy a 1GWh BESS at the Stoney Creek site in New South Wales, Australia.
