Energy Vault has signed an agreement with Consumers Energy to deliver two battery energy storage system (BESS) projects totalling 75 MW/300 MWh in Michigan. The projects will be located in Iosco and Bay counties. The 45 MW/180 MWh Weadock BESS project will be developed at the former John C. Weadock Power Plant site in Hampton Township, while the 30 MW/120 MWh Iosco County BESS project in Oscoda Township.
Additionally, both the projects will be developed under Energy Vault’s B-VAULT suite, and will integrate the X-Vault platform and Vault-OS energy management system to control, manage and optimise operations. Battery deliveries are scheduled to begin in the fourth quarter of 2025. Construction will begin in the first quarter of 2026, and commercial operations will commence by the fourth quarter of 2026. Local permitting efforts are underway in collaboration with township authorities to support project development.
In July 2025, Energy Vault secured $18 million in project financing for the Cross Trails 100 MW BESS project serving the Texas ERCOT market. The project reached commercial operations in June 2025 and is supported by a 10-year off-take agreement with Gridmatic.
