The Cross Trails BESS project is Energy Vault's first developed, owned, and operated battery energy storage system. At 57 MW / 114MWh, the system provides energy and ancillary services to support renewable energy production and improve grid resiliency in the Electric Reliability Council of Texas (ERCOT) region. The project leverages Energy Vault's fully integrated solution stack of hardware, software, and service offerings. Cross Trails also serves as the first deployment of Energy Vault's second generation B-VAULTTM AC product.
The project is backed by a significant partnership with Gridmatic, featuring a 10-year offtake agreement set to begin in Q2 2025. This agreement marks the first physically settled revenue floor contract signed for a BESS in ERCOT and leverages Gridmatic's AI-based forecasting capabilities, which have demonstrated leading performance in Day Ahead energy trading within the ERCOT market. As part of the agreement, Gridmatic also provides QSE (Qualified Scheduling Entity) services. The Cross Trails project reached COD ahead of schedule in May of 2025.
