Energy Vault Holdings Inc. along with Wellhead Electric Company, Inc. and W Power, LLC announced that the Stanton Battery Energy Storage System (SBES) is fully operational. The 68.8 MW/275.2 MWh battery energy storage system (BESS) in Stanton, California, one of the largest energy storage systems in Southern California, has commenced full-scale operations. The Stanton system is providing clean power and improved grid resiliency in Southern California Edison Southwest LA region by directly supporting and providing power for a high-demand load center.

The BESS is located nearby the 98 MW SERC Hybrid Gas Turbine Project in Stanton, California, and in addition to increasing the resiliency of the local electrical grid, the BESS reduces the overall carbon intensity of the local grid. Despite being located on a site with limited flexibility, construction of the BESS was completed in under five months, saw zero workplace injuries, and achieved maximum power output in record time. Testing conducted in July 2023 during a record-breaking heatwave met or exceeded expectations and technical performance commitments.

The BESS is now being operated at full capacity and with continued high performance by Wellhead, one of the most experienced developers and operators of innovative energy generation and storage facilities in California. Wellhead and W Power served as the developers for the project, and Energy Vault served as the engineering, procurement and construction (EPC) contractor and system integrator, which was built with the Energy Vault?s proprietary X-Vault integration platform and Vault-OS Energy Management System to control, manage and optimize the BESS operations.
