Rooftop solar strengthens electric grid during recent heat wave

MAINE PUBLIC • July 3, 2025

Experts say that roof mounted solar panels moderated electric demand and prices on the New England electric grid during the recent heat wave. Jamie Dickerson with Acadia Center, an energy nonprofit, said so-called ‘behind the meter’ solar sent to homes and businesses reduces the overall need for electricity at peak periods. During intense heat on June 24, generation from homes and businesses helped keep the grid running even as operator ISO New England was forced to fire up reserve energy resources after it fell short of requirements. "Clean energy in fact saved consumers millions of dollars in wholesale electricity market costs and played a vital role in keeping the light on and the air conditioning running," Dickerson said.
