California utility Pacific Gas and Electric Company (PG&E) announced it has surpassed 1 million customers with solar systems connected to its grid.
Customers have been making solar connections in PG&E territory for over 30 years. Solar adoption has evolved from limited activity in the 1990s, to steady growth in the 2000s, to rapid expansion in the 2010s, culminating in more than half a million new interconnections between 2020-2025 and more than 70,000 new solar installations annually over the past two years. PG&E’s solar connections across Northern and Central California include residential setups, commercial designs and utility-scale projects.
“PG&E supports solar at every scale and has enabled more solar adoption than any utility in the country,” said Jason Glickman, EVP of strategy and growth at PG&E. “Reaching one million interconnections is ultimately a story about our customers — but it’s also a story about what comes next. The future of solar is not just about producing clean electricity. It’s about integrating solar and storage in ways that deliver value for all customers by strengthening the grid and improving resilience.”
PG&E is already looking toward the future with its expansion of virtual power plants (VPPs) — networks of customer‑owned solar and battery systems that can be dispatched in coordination to support the grid during periods of high demand or local constraints. The utility has also been active in establishing bidirectional EV charging pilots.
