California energy officials on Tuesday approved a large-scale battery project, celebrating its potential to help the state meet its renewable energy goals and improve grid reliability.

What happened: The California Energy Commission green-lighted the Potentia-Viridi Battery Energy Storage System, a 400-megawatt Alameda County battery project backed by developer Clearway Energy Group.

Why it matters: The Newsom administration has made the construction of utility-scale batteries a centerpiece of its clean energy goals. They work by storing excess electricity produced by the state’s solar panels during the day and discharging it when the sun goes down.
