No-Cost Mass Save® Energy Assessment with HomeWorks Energy

Merrimac Municipal Light Department and HomeWorks Energy are teaming up to help residents with natural gas heat access the Mass Save® program!

Energy Efficiency Rebates

We offer rebates on energy-efficient appliances and tools designed to replace older, less efficient models. By upgrading to state-of-the-art technology, you’ll save both energy and money.

Merrimac Light vs National Grid

We’re dedicated to informing our customers of the benefits of public power versus investor-owned utilities like National Grid, and one of the major benefits is the difference in cost.
