• Built with Energy Vault’s proprietary B-Vault AC block and managed by the VaultOS Energy Management System, the St. Gall Battery Energy Storage System (BESS) is fully grid-connected, providing clean power and improving grid resiliency in Fort Stockton, Texas area

WESTLAKE VILLAGE, Calif. / Jul 24, 2024 / Business Wire / Energy Vault Holdings Inc. (NYSE: NRGV) ("Energy Vault" or the “Company”), a leader in sustainable, grid-scale energy storage solutions, today announced the successful deployment of its proprietary B-Vault AC block and VaultOS™ Energy Management System supporting Jupiter Power’s St. Gall Battery Energy Storage System (BESS).

Located near Fort Stockton, Texas, the 100 MW/200 MWh BESS is providing energy and ancillary services to the Electric Reliability Council of Texas (ERCOT) and has commenced full-scale commercial operations.

Energy Vault served as the engineering, procurement, construction and commissioning (EPC) contractor and system integrator for the project and will deliver the second BESS deployment. Both BESS systems are built with Energy Vault’s proprietary X-Vault integration platform using Energy Vault’s proprietary UL9540 certified B-VAULT™ product, and Vault-OS Energy Management System to control, manage and optimize the BESS operations. Energy Vault’s innovative system architecture provides customer optionality with both battery and inverter suppliers, while unique AC-coupled and DC-coupled configurations provide the drop-in flexibility needed for any project.

"Jupiter Power is proud to continue providing critically needed dispatchable capacity to the ERCOT market with projects like our St. Gall BESS,” said Michael Geier, Chief Technology Officer, Jupiter Power. “The Energy Vault team’s deep expertise and collaborative approach were critical to the rapid design and commissioning of this unique, AC-coupled BESS configuration.”

“The streamlined commissioning process and delivery of the St. Gall BESS, as well as Jupiter Power’s decision to expand this partnership, are direct results of not only Energy Vault’s commitment to a customer-centric approach, but of Jupiter Power’s strong understanding of market dynamics and our AC block solution specifically,” said Akshay Ladwa, Chief Engineering Officer, Energy Vault. “This is an important milestone in our ongoing partnership with the Jupiter Power team to deliver on a robust pipeline of BESS projects across the United States, and we would like to thank their team for serving as such excellent partners.”

Today’s announcement marks a key milestone in the ongoing collaboration between Energy Vault and Jupiter Power. In 2022, the companies announced an agreement to secure 2.4 GWh of supply chain equipment and services that will be integrated and delivered through Energy Vault's hardware and software management platform in Jupiter Power's battery energy storage projects. This announcement also serves as a demonstration of the continued momentum and adoption of Energy Vault’s B-VAULT product, coming on the heels of recently completed BESS deployments with partners such as NV Energy and Wellhead Electric/W Power, as well as a newly signed agreement with ACEN Australia. To date, Energy Vault’s B-VAULT portfolio consists of more than 2 GWh in total projects either deployed or currently in development.
