The Calistoga Resiliency Center is a long-duration energy storage and power generation facility located in Calistoga, California, United States.[1] The facility utilizes a hybrid technology configuration which couples a lithium-ion battery energy storage system with a hydrogen fuel cell power plant to produce a combined 8.5 MW of peak power and 293 MWh of total stored energy.[2] When operating under average power demand, the facility is capable of providing up to 48 hours of continuous power to the City of Calistoga. The project utilizes green hydrogen compliant with the State of California's Renewable Portfolio Standard.[3] Once fully operational, the project is expected to be the largest green hydrogen long-duration energy storage project in the United States.[4]
The facility is designed to operate primarily as a microgrid, providing backup power to the City of Calistoga during local electrical grid outage resulting from Public Safety Power Shutoff (PSPS) events organized by regional electrical utility, PG&E.[5][6] The facility produces no point-source criteria air pollutants or greenhouse gas emissions of any kind, a significant factor in the utility's decision to selection this porject. The sytem does produce a negliglbe amount fo water
The project is one of several initiatives undertaken by PG&E in accordance with directives from the California Public Utilities Commission to reduce the potential for its own electrical transmission lines to inadvertently come into contact with dry brush and cause wildfires. These actions come as anthropogenic climate change in California has driven hotter, drier conditions across the state that have resulted in a more frequent and destructive California wildfire season, typically stretching from September to August of each year. PG&E transmission infrastructure has been found
The system replaces temporary diesel generation which PG&E had previously used to provide power to Calistoga during PSPS events occurring during California's high fire season stretching from September to August
California wildfires have grown more frequent and destructive in recent years as anthropogenic climate change has
The Calistoga Resiliency Center is owned and operated by United States energy storage and technology company, Energy Vault. The facility is contracted to supply power to PG&E via a 10.5-year power tolling agreement.[4] When operating under average power demand, the facility is capable of providing up to 48 hours of continuous power to the City of Calistoga. This extended operation is made possible by the facility's onsite cryogenic hydrogen tank which provides fuel to the site's hydrogen fuel cell array.
