1,200-MWh energy storage project comes online for PG&E

A large new battery storage project has switched on in Poway, California, near San Diego. Built by Arevon Energy, the Nighthawk Energy Storage Project can store 1,200 megawatt-hours of electricity using lithium iron phosphate (LFP) batteries, a common, stable type of battery chemistry. It runs under a long-term agreement with Pacific Gas and Electric (PG&E) and is meant to help keep the regional grid steady, especially when demand for electricity spikes.

For homeowners, this isn't a rebate or program you can apply for. It's grid infrastructure — the kind of large-scale storage that helps utilities avoid blackouts and manage the ups and downs of solar and wind power. If you live in the San Diego area served by PG&E, projects like this are part of what keeps your power supply more reliable, particularly during high-demand periods.

The project is also expected to bring in more than $30 million in property tax revenue over its lifetime for the local area, and it employed over 130 workers during peak construction. Arevon has also set up partnerships with local groups in Poway, including organizations supporting special needs services, youth programs, and first responders.

There's nothing here that changes what a homeowner needs to do or qualifies for. It's simply a sign that battery storage continues to expand across California's grid, which may make local power supplies somewhat more resilient over time.
