Billerica Residents
Reduce Energy Use and Lower Your Costs
Lower Your Year-Round Energy Costs
The Towns of Billerica and Chelmsford are working with Mass Save® partner HomeWorks Energy to encourage home energy efficiency and expand access to Mass Save incentives.
Through this initiative, residents can access a range of energy-efficiency services and incentives, including weatherization improvements and high-efficiency heating and cooling technologies.
Start with a No-Cost Home Energy Assessment
A Home Energy Assessment provides a comprehensive review of your home’s energy performance. During the assessment, a qualified Mass Save program vendor will identify opportunities to improve efficiency and reduce energy use.
Potential Benefits Include:
-
A customized home energy report
-
Air sealing improvements at no cost for eligible measures
-
75-100% off recommended insulation upgrades (eligibility-dependent)
-
Rebates of up to $8,500 for heat pump systems (higher incentives may be available for income-qualified households)
-
0% financing for approved energy-efficiency projects
-
No-cost, energy-saving items such as programmable thermostats and water-saving devices
Discounted Electricity Rates Available for Heat Pump Owners
Beginning November 1, 2025, National Grid is discounting electric rates for residents who heat their homes with heat pumps. This seasonal rate applies to electricity usage from November 1 through April 30 to help offset energy costs during colder months. If you received a heat pump rebate from National Grid through Mass Save, you may be automatically enrolled in the heat pump rate after November 1, but please check with National Grid to ensure you are registered.
Important Information
- Incentives, rebates, and financing options are subject to change and determined by the Mass Save program
