California IOU Grid Capacity to Fully Serve Local Load with Distributed Solar+Storage Systems during Summer Peak/Net Peak Hours

Across the three large California IOUs, distribution substations could absorb an estimated 17,536 MW of full discharge from distributed front-of-the-meter systems during the summer peak and net peak hours in 2032, 32% of the California Energy Commission’s 2025 Integrated Energy Policy Report Mid-Case Planning Forecast
for that year.
