New England residents saved $130 million in energy costs during the 2026 June-July heatwave, all due to rooftop solar panels

New England saved $130 million in energy costs during the June-July 2026 heatwave due to rooftop solar panels, according to an Acadia Center report.

Distributed solar projects contributed more than six gigawatts of electricity to the grid in that period.

On July 2, solar arrays saved $39 million to $54 million and outperformed the region's nuclear fleet in power generation.

Rooftop solar provided up to 25% of total electric demand at peak times, reducing reliance on other fuel sources.
