Construction has begun on Arevon Energy’s highly anticipated $600 million energy storage facility in Daly City, California. The Cormorant Energy Storage Project, designed to deliver 250 megawatts (MW) of energy with a capacity of 1,000 megawatt-hours (MWh), is expected to be operational by 2027. Once completed, the facility will have the capability to power approximately 321,000 homes for up to four hours.

A milestone for clean energy in California

The Cormorant Energy Storage Project will use lithium iron phosphate (LFP) battery technology, a widely regarded solution for long-term energy storage. This project represents a key step forward in California’s ongoing efforts to stabilize its energy grid and meet its ambitious clean energy goals.

Justin Johnson, CEO at Arevon, emphasized the significance of the project, stating, "The start of construction marks an important milestone for the Cormorant project and the Daly City community. Projects like Cormorant are critical to strengthening California’s energy grid by storing power when it’s abundant and delivering it when it’s needed most. Arevon is proud to continue investing in infrastructure that supports reliability, affordability, and California’s long-term clean energy goals."

Expansion and collaboration

Originally planned with a capacity of 188 MW and 752 MWh, the Cormorant project has since been scaled up to meet greater energy demands. The facility will be owned and operated by Arevon under a long-term offtake agreement with MCE, an electricity provider serving over 1.8 million residents and businesses across Contra Costa, Marin, Napa, and Solano counties.

Shanelle Montana, Chief Development Officer at Arevon, highlighted the importance of community involvement in the project’s development. "The Cormorant project demonstrates the importance of working closely with local leaders and community members as we develop projects that will operate for decades", Montana said. "Community engagement is not simply a box to check - it is a commitment to being present, authentic, and aligned with the people who will live alongside our projects. Arevon looks forward to continuing its partnership with the community throughout Cormorant’s construction and long-term operations."

Job creation and development

Construction efforts, led by Primoris as the engineering, procurement, and construction (EPC) contractor, are expected to create approximately 175 jobs at peak activity. Arevon’s broader portfolio includes 3.7 gigawatts (GW) of renewable energy projects currently in operation, with an additional 550 MW under construction.

The Cormorant Energy Storage Project is set to play a critical role in supporting California’s renewable energy infrastructure and addressing the state’s pressing energy needs. With construction underway, the project marks a significant step toward a cleaner, more reliable energy future.
