Partners announce operations of California battery storage system

Storage company Energy Vault, along with Wellhead Electric Company and W Power, announced that the Stanton Battery Energy Storage System (SBES) is now fully online.

The 68.8 MW/275.2 MWh battery system is located near the 98 MW SERC Hybrid Gas Turbine project in Stanton, California.

SBES was constructed in under five months and met performance expectations during testing in July 2023, the companies said.

Wellhead operates the facility. Wellhead and W Power developed the project, with Energy Vault as the EPC contractor and system integrator. Energy Vault’s X-Vault integration platform and Vault-OS Energy Management System is used to control, manage and optimize system operations.

The Stanton Energy Reliability Center (SERC) is a 98 MW natural gas-fired, simple-cycle facility with two GE LM6000 hybrid enhanced combustion turbines that provide operational flexibility as a synchronous condenser, and an integrated 10 MW GE battery storage system.

Each combustion turbine is powered by a system equipped with selective catalytic reduction, air emissions control equipment and associated support equipment for nitrogen oxides (NOx), along with an oxidation catalyst for carbon monoxide and volatile organic compound control.

The two sets of lithium-ion batteries are housed in purpose-built battery enclosures, each with a capacity of 10 MW (total 20 MW) and 4.3 MWh storage (total 8.6 MWh). The battery system could be charged either by the grid or the on-site combustion turbines. The batteries enable the gas turbines to supply spinning reserve by providing approximately 10 minutes of ramping profile for the turbines.

SERC began commercial operation on October 6, 2020.
