In Massachusetts, the decades-old steam pipes-based district heating system serving Boston and Cambridge is getting electrified, with a 42 MW electric boiler and a 35 MW industrial-scale heat pump linked to the Charles River! You can find the full story at PV Magazine.

Furthermore, the roughly 100,000 heat pump households in Massachusetts now benefit from lower winter electricity rates starting this November, thanks to a new state policy for clean affordability!

Elsewhere, across America, states are leading the way on deploying clean, affordable, energy-efficient, money-saving, and highly effective heat pumps! Snowy Maine is at the forefront: after setting a goal in 2019 to deploy 100,000 heat pumps by 2025, the Pine Tree State met that goal two years early in 2023 and is now targeting another 175,000 new heat pumps by 2027!

A recent study found that Maine households who have installed heat pumps are seeing 60% savings on their yearly energy bills compared with fossil fuels. Maine’s new state energy-efficiency plan to accelerate this trend is forecast to support 38,000 new whole-home heat pump systems and long-term lower electricity bills across the state by over $490 million.
