Calistoga Resiliency Center

The  Calistoga Resiliency Center (CRC) is a hybrid energy storage facility that couples two commercial clean energy technologies: hydrogen fuel cells and lithium-ion batteries. The 293MWh system is designed to provide 48 hours of continuous energy, and a peak instantaneous power output of 8.5MW during regional Public Safety Power Shutoff (PSPS) events.   When Calistoga's local microgrid is islanded from the regional electrical network during a PSPS event, the CRC will utilize green hydrogen in fuel cells to generate electricity, providing power to the local community.

Energy Vault's B-VAULT™ DC battery will work in conjunction with the fuel cells to provide instantaneous response and grid-forming capabilities, ensuring stable power supply throughout the event's duration. This integrated system results in zero point-source greenhouse gas emissions and is fully compliant with California's Renewable Portfolio Standard (RPS), meeting PG&E's unique ultra-long duration energy storage needs.   This complex system is managed by Energy Vault’s technology-agnostic VaultOS^TM Energy Management System (EMS), which is able to provide full control and coordination across all project subsystems in order to provide a seamless operational experience for Calistoga.
