Insights
PG&E's Calistoga microgrid advances utility resilience strategy with innovative zero-emission technology to mitigate wildfire-related outages.
The successful deployment of the Calistoga Resiliency Center (CRC) represents a significant advancement in PG&E's wildfire mitigation strategy. This 293 MWh hybrid microgrid integrates hydrogen fuel cells with lithium-ion batteries to provide power to approximately 1,600 customers during Public Safety Power Shutoffs (PSPS)—a critical capability in California's increasingly fire-prone regions. The system's 8.5 MW peak output and 48+ hour runtime address a fundamental challenge for PG&E: maintaining service reliability while prioritizing safety during extreme weather conditions.
What makes this installation particularly notable is its zero-emission profile, which aligns with California's Renewable Portfolio Standard while meeting PG&E's multi-day power requirements. The CRC represents the 13th microgrid deployed by PG&E since 2021, but stands out as the largest and first fully renewable system. This positions the utility favorably with regulators as it demonstrates commitment to both resilience and sustainability goals simultaneously.
The project exemplifies PG&E's multi-faceted microgrid strategy, which includes distribution microgrids, community-driven multi-customer microgrids, and Remote Grid services. The approach allows PG&E to reduce wildfire risk by potentially removing overhead lines in high-risk areas while still meeting customer needs. This represents a significant evolution in utility infrastructure planning—shifting from traditional centralized distribution to more flexible, localized solutions that can operate independently during emergencies while maintaining integration with the broader grid during normal operations.
First-of-a-kind and fully sustainable microgrid platform, developed to support the long-term vision of the California Public Utility Commission and PG&E to ensure

"This project is a major milestone in our mission to deliver sustainable, resilient energy solutions to communities most vulnerable to climate-driven grid disruptions," said Craig Horne, Senior Vice President, Advanced Energy Solutions, Energy Vault. "The Calistoga Resiliency Center exemplifies the power of innovation and partnership, and it marks a significant step forward in the execution of our 'Own & Operate' strategy, which enables us to deliver long-term value through recurring revenue and community impact."
When operating in island mode, the CRC utilizes hydrogen fuel cells for electricity generation, providing essential power to the community. After supporting black-start and grid forming requirements of the microgrid, Energy Vault's B-VAULT™ DC battery technology works in concert with the fuel cells, ensuring instantaneous response and maintaining grid stability throughout operation. The use of liquid hydrogen enables extending run time through delivery and transfer into the onsite storage tank without interrupting power supply to the
