Energy Vault Holdings, a provider of sustainable, grid-scale energy storage solutions, Wellhead Electric Company, and W Power, a woman-owned developer and owner of power generation facilities in California, have initiated operations at the 68.8 MW/ 275.2 MWh Stanton Battery Energy Storage System (SBES) in Stanton, California.
The BESS, located adjacent to the 98 MW SERC Hybrid Gas Turbine Project in Stanton, California, is not only 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 but is also helping reduce the overall carbon intensity of the local grid.
According to the companies, the battery energy storage system (BESS) is now one of the largest energy storage systems in Southern California.
Despite limited flexibility on-site, BESS construction was completed in under five months with zero workplace injuries and achieved maximum power output in “record” time. For example, testing conducted in July 2023 during record-breaking heatwaves met or exceeded expectations and technical performance commitments.
Currently, the system is operated at full capacity and with continued high performance by Wellhead.
While Wellhead and W Power served as the developers for the project, Energy Vault was the engineering, procurement, and construction (EPC) contractor and system integrator.
The project was also 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.
