About the Project

The Condor Energy Storage Project is located in Grand Terrace, at the corner of Taylor Street and Main Street, with close access to an electrical substation and the transmission system. Once complete, the 200 megawatt (MW)/800 megawatt-hour (MWh) project will be able to power up to 150,000 homes for up to four hours, strengthening the electric grid.

The main project 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 is working closely with the community to ensure any 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, capturing 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 nor harmful radiation 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.
