PG&E surpasses 1 million customers with solar systems connected to its grid

The milestone includes residential, commercial, and utility-scale solar connections developed over more than three decades. PG&E is also pointing toward virtual power plants, where customer-owned solar and battery systems can be coordinated to support the grid during high-demand periods or local constraints. For the solar market, the key point is that high distributed PV penetration is pushing utilities from simple interconnection growth toward active solar-plus-storage grid orchestration.
