A new report from Synapse Energy Economics for the Solar Energy Industries Association finds that solar energy and energy storage in Massachusetts could deliver more than $313 million per year in consumer savings.

The report looked at a future that included continued growth in solar energy and energy storage in that state through 2030 and compared it to a future where no new solar projects are built after 2025. The study found that staying on the clean energy path provided energy cost reductions for the state, as well as lower exposure to unpredictability and volatile price swings, and increases in grid reliability.

“As SEIA and Synapse’s analysis demonstrates, solar and energy storage are incredible levers that the Commonwealth can pull to deliver utility bill savings, winter reliability, and climate benefits to the state’s residents,” State Rep. Mark J. Cusack (D-Braintree), House Chair of the Joint Committee on Telecommunications, Utilities, and Energy, said. “To help realize these benefits, we are prioritizing legislation this session that will eliminate barriers blocking these cost-competitive resources. We look forward to collaborating with our state government, clean energy industry, and environmental partners to pass meaningful legislation.”

In addition to seeing Massachusetts customers saving $313 million per year on electricity costs starting in 2030, the study found the New England region would see $684 million in benefits. The study also found solar and storage would provide 44 percent of the avoided energy-cost benefits during the winter months, when the state faces its greatest reliability challenges. New solar and storage would avoid 29 billion cubic feet of natural gas, the equivalent of 25 percent of the state’s current electric sector gas use. It would also avoid 1.6 million metric tons of CO2 in 2030, the equivalent of removing nearly 350,000 cars from the road for a year.

“As SEIA’s analysis shows, solar and energy storage are key to lowering energy costs and provide vast economic benefits for all customers,” Massachusetts Department of Energy Resources Commissioner Elizabeth Mahony said. “Adding more solar energy and energy storage in Massachusetts will also add needed reliability to our electric grid and is an opportunity to support local clean energy companies and jobs.”
