In December 2018, Wellesley was designated a "SolSmart Silver" community for making it faster, easier, and more affordable for homes and businesses to go solar.
Currently, the Town has:
- 129 Residential solar installations
- 10 Commercial solar installations
- 3 WMLP installations
These 142 solar systems total 1,138 MW.
WMLP has also entered into a Letter of Intent to lease the roof of a private development at 900 Worcester Street in order to install approximately 1 MW of rooftop solar on the building. Beginning in the Spring of 2019, this arrangement is expected to double the amount of solar power in town.
