PG&E, the largest utility in the U.S. in terms of solar interconnections, has focused on modernizing the grid for safe and reliable two-way power flows, with a recent emphasis on virtual power plant deployment. Their investments in grid automation, advanced forecasting, streamlined interconnection, and the integration of solar paired with battery storage have positioned California as the top state for residential solar and overall solar capacity. Customers in California have access to rebates and credit rates for solar generation, with solar plus storage systems offering backup power during public safety power shutoffs. This has led to increased interest in solar and resiliency options in the state.
