St. Gall I & II Battery Energy Storage System
Project Overview
Rapid Delivery, Proven Performance
Energy Vault's B-VAULT™ AC battery energy storage system (BESS) shifts regional wind and solar generation, stabilizing the Texas grid while increasing customer revenue.
Located near Fort Stockton in Pecos County, Texas, the St. Gall Battery Energy Storage System (BESS) is a 200 MW-ac / 400 MWh-ac, multi-phased project utilizing B-VAULT™ battery containers.
The projects operate within the Energy Reliability Council of Texas (ERCOT) energy and ancillary services markets, generating merchant revenue by providing energy shifting and reliability services to the Texas grid.
At the St. Gall site, Energy Vault delivered comprehensive Integration, Engineering, Procurement, and Construction (EPC) services. Leveraging its extensive commissioning and start-up (CSU) expertise and the B-VAULT's user-friendly system architecture.
During operation, Energy Vault's proprietary EMS software, VaultOS™, monitors and controls all aspects of the BESS, from daily operations to advanced market bidding and system maintenance. While undergoing testing, the St. Gall system surpassed ERCOT's 250ms maximum requirement for Fast Frequency Response (FFR).
