Jupiter Power has tapped Energy Vault for another 100-megawatt (MW) battery energy storage system, aimed at bolstering grid resiliency in the Electric Reliability Council of Texas region, according to a June 4 news release.

Project construction is underway with commercial operations expected to start by the end of the summer. Energy Vault’s B-Vault and VaultOS Energy Management System are being used for the project.

“As one of the largest battery storage developers and operators in the U.S., we look for partners who can keep pace with our ambition and scale,” said Jupiter Power CTO Michael Geier. “With more than 2,500 MWh in operation or construction, we’re excited to continue building with Energy Vault at this critical site and appreciate their ability to deliver solutions tailored to our needs.”

The agreement for additional battery storage followed the July 2024 completion of an initial 100-MW system.
