About the Project

The Nighthawk Energy Storage Project is located in Poway at the corner of Paine Street and Kirkham Way, allowing close access to the Sycamore Canyon Substation and transmission system.

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 an 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 has worked closely with the City of Poway to ensure that the project construction is compliant with all applicable codes and standards.

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 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 peak demand.

Arevon is a U.S. energy leader with a proven track record of safely constructing and operating utility-scale solar and battery storage projects across the country.

Battery energy storage systems do not generate any emissions or harmful radiation, and they utilize advanced technology selected for its strong safety performance. Battery storage systems also contain protection and control features, including a battery management system that shuts down when operational environments are anything less than optimal. Arevon spent several years working with the local fire department to obtain necessary permits prior to beginning operations.
