Energy Vault, Jupiter Power expand partnership with 200 MWh battery project in ERCOT

Energy Vault and Jupiter Power are expanding their partnership with a new 100 MW/200 MWh BESS in the Electric Reliability Council of Texas (ERCOT) region. This project follows the completion of an initial 100 MW/200 MWh BESS in July 2024.

The BESS is already well underway, with the companies’ statement noting that the new BESS is under construction and is expected to be commercially operational within months, with a target timeline of the end of summer 2025.

The project will be built with Energy Vault’s X-Vault integration platform and its UL9540-certified B-VAULT product. The VaultOS Energy Management System will control and optimize the system’s operations.

This project is part of a larger collaboration between the two companies that began in 2022, with an agreement for 2.4 GWh of supply chain equipment and services.

Michael Geier, chief technology officer at Jupiter Power, said, “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. 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.”

Marco Terruzzin, chief commercial and product officer at Energy Vault, said, “Jupiter’s BESS projects portfolio has reached a critical mass in ERCOT and we’re proud to continue serving as a partner to Jupiter Power in the ultimate endeavor to decarbonize the grid in an economically effective fashion.”

Energy Vault has been active globally, with recent announcements of a 1 GWh battery acquisition in Australia and a technology transfer agreement in India for the manufacturing of BESS. The company’s B-VAULT portfolio has now reached over 2 GWh of projects either deployed or in development.
