AUGUSTA — Gov. Janet Mills signed a bill Tuesday that will allow Maine homeowners to continue receiving credits on their electricity bills for excess solar energy fed onto the power grid.
By signing the bill, Mills both ended the planned phase-out of the credit system for excess solar energy and rescinded a related requirement that utilities install a second meter on homes with solar energy systems.
“For too long, Maine has lagged behind other states in embracing policies that advance the future of solar power,” Mills said in a statement. “That ends today. By signing into law this bill, we are restoring net metering, resetting Maine’s solar policy, and charting the course for the growth of solar power to lower electricity bills and combat climate change.”
Maine’s solar energy policies have been in flux for years due largely to former Gov. Paul LePage, a Republican who led efforts to phase out the “net metering” incentives utilized by solar-powered homes and businesses. That dynamic changed dramatically last November, however, with the election of Mills as well as Democratic majorities in both chambers of the Legislature.
Solar energy advocates and installers have been pushing for years to rewrite LePage-era energy policies they said were holding back an industry that is booming elsewhere around the country. LePage argued that non-solar electricity ratepayers were subsidizing solar-powered homes and businesses through net metering.
One of the major changes in the bill signed by Mills, L.D. 91, would repeal the requirement that solar-powered homes and businesses have a second meter installed to monitor the output of solar panels. Solar advocates compared that “gross metering” requirement to allowing grocery stores to charge for fruits and vegetables grown in home gardens.
“The first step in moving toward a clean energy future is not unfairly penalizing those who choose to invest in solar power for their homes or businesses,” Dylan Voorhees, clean energy and climate director for the Natural Resources Council of Maine, said in a statement. “The repeal of gross metering will remove the harmful fees utilities are now charging solar customers for using their own solar power.”
Mills signed the bill — sponsored by Rep. Seth Berry, D-Bowdoinham — at Rocky’s Stove Shoppe and Chimney Services, an Augusta business that utilizes solar panels.
