As a municipal utility, Wellesley Municipal Light Plant sets its own rates and policies independently, separate from Mass Save and ConnectedSolutions programs that serve investor-owned utility customers. However, Wellesley Municipal Light Plant offers its own local rebate programs. Wellesley Municipal Light Plant offers net metering, allowing solar customers to receive credits for excess energy sent back to the grid. The utility offers a solar rebate of $1.20 per watt up to $12,000. Heat pump rebates of up to $8,500 are also available.

The federal residential solar tax credit (Section 25D) expired at the end of 2025. State and utility-level incentives are now the primary financial benefits for homeowners going solar. NuWatt Energy handles the entire process from system design through permits and Wellesley Municipal Light Plant interconnection, ensuring you receive every available rebate.
