About the Project

The Cormorant Energy Storage Project is located in Daly City, at the corner of Carter Street and Saddleback Drive. This location provides access to an electrical substation and the transmission system. Once complete, the 250 megawatt (MW)/1,000 megawatt-hour (MWh) project will be able to power up to 200,000 homes for up to four hours, strengthening the electric grid.

The main battery storage components are the battery storage containers, which include racks of batteries, control units, fire prevention and fire protection equipment; voltage transformers and inverters; and a small on-site substation. The containers typically range from 10 to 25 feet long, 6 to 8 feet deep, and 6 to 10 feet high. The project team will work closely with the community to ensure impacts are mitigated and the facility fits in as seamlessly as possible.

How It Works

Utility-scale battery storage systems are large banks of batteries connected to the electric grid via a transmission line.

Battery storage adds greater reliability and resilience to the electrical grid. During times of peak energy generation, such as when power from solar or wind is in abundance, batteries can be charged to capture excess generation. Batteries can then discharge this stored generation into the grid during times of peak energy demand.

Arevon is a leading renewable energy company with a proven track record of safely constructing and operating utility-scale energy projects across the country.

Battery storage devices do not generate any air emissions and involve little to no fire risk when properly designed, installed, tested and operated. The battery storage systems contain protection and control features, including a battery management system that shuts down when operational environments are anything less than optimal. The project must obtain necessary permits and receive sign-off and approval from the local fire marshal and permitting authorities before the facility may be considered operational.
