Arevon Energy, an Arizona-based renewable energy developer, has commenced operations at its 300 megawatt/1,200 megawatt-hour Nighthawk Energy Storage Project in Poway, California, it said on Wednesday.
The facility, developed, owned and operated by Arevon, is the company's largest standalone battery storage project and relies on lithium-iron phosphate battery technology, Arevon said in a statement.
The project is expected to help strengthen grid reliability in San Diego and provide enough power for up to 385,000 homes for up to four hours.
It has secured a long-term agreement for the project with PG&E (PCG) subsidiary Pacific Gas and Electric Company.
Arevon owns and operates over 6.3 gigawatts of solar and energy storage projects across 18 states and is currently constructing 370 MW of new capacity. In California, it has over 4 GW in operation, the company said.
