Energy Vault and PG Launch Hybrid Microgrid to Enhance Power Resiliency in Calistoga

What's Happening?

Energy Vault, a Switzerland-based energy storage company with U.S. headquarters in California, has partnered with Pacific Gas & Electric (PG&E) to deploy a hybrid microgrid energy project in Calistoga, California. The Calistoga Resiliency Center (CRC) integrates advanced hydrogen fuel cells with lithium-ion batteries to provide a sustainable solution for power resiliency, particularly during wildfires and extreme weather events. The microgrid system, with a capacity of 293 MWh, is designed to maintain power during Public Safety Power Shutoffs (PSPS), a protocol used to mitigate wildfire risks from electrical equipment. The CRC can deliver at least 48 hours of continuous power supply with a peak output of 8.5 MW during PSPS events. This zero-emission system aligns with California's Renewable Portfolio Standard and meets PG&E's long-duration energy storage requirements.

Why It's Important?

The deployment of the Calistoga Resiliency Center is significant as it addresses the growing challenges of wildfire risks in California, providing a model for future utility-scale hybrid microgrid systems. The project enhances grid resiliency and supports communities vulnerable to climate-driven disruptions. By utilizing hydrogen fuel cells and lithium-ion batteries, the CRC offers a scalable and bankable solution that can be replicated across regions prone to wildfires. This initiative not only contributes to environmental sustainability but also ensures reliable power supply during emergencies, benefiting local residents and essential services.

What's Next?

Energy Vault plans to expand its 'Own & Operate' strategy, leveraging the success of the Calistoga Resiliency Center to deploy similar microgrid systems in other regions. PG&E continues to support community-driven microgrid projects through its Community Microgrid Enablement Program and Microgrid Incentive Program, with commitments to fund additional microgrids in California. These efforts aim to enhance electric system safety and reliability while reducing costs for customers.

Beyond the Headlines

The Calistoga Resiliency Center exemplifies the power of innovation and partnership in addressing climate-driven grid disruptions. The use of hydrogen fuel cells and advanced battery technology highlights the potential for clean energy solutions to transform power infrastructure, offering long-term benefits for communities and the environment.
