Located near Fort Stockton, in Pecos County, Texas, the St. Gall Battery Energy Storage System (BESS) is a 100 MW/200 MWh project utilizing 76 of Energy Vault’s fully integrated B-VAULT™ AC battery products.
The project operates within the Energy Reliability Council of Texas (ERCOT) power and ancillary services market, generating merchant revenue for Jupiter Power by providing additional energy shifting and reliability services to the Texas grid.
Energy Vault's full Engineering, Procurement, and Construction (EPC) wrap services and the B-VAULT™ AC streamlined the installation process and delivered a fully operational system in the face of multiple site level challenges.
Energy Vault’s proprietary EMS software, VaultOS™, will be used to monitor and control all aspects of the BESS, from daily operations to advanced market bidding and system maintenance. During testing, the St. Gall system showcased a 180ms response time, surpassing ERCOT's 250ms maximum requirement for Fast Frequency Response (FFR).
