1 Important Alert

Heat Advisory

Forecasters are calling for a run of high temperatures and humidity this weekend. We are prepared for increased energy demand and will be closely monitoring the weather and our system. We also want to ensure you are prepared as prolonged temperatures of 90°F or higher can lead to heat-related illnesses. Please stay hydrated and cool and regularly check on the elderly, young children and those with chronic illnesses in your life as they are at a higher risk.

Residential Renovations and Additions

Save money, and energy, with Residential Renovations and Additions

Looking to renovate or add a new addition to your home? The Massachusetts Residential New Construction Renovations & Additions Path can help. The program promotes energy-efficient upgrades and offers incentives for upgrading single- or multi-family homes with three stories or less.

Homes must be within our service territory, and most are eligible for upgrades that may include, but not limited to:

  • Insulation
  • Heating, ventilation, and air conditioning
  • Water heating equipment
  • Windows
  • Lighting
  • Air and duct sealing

Calculating Incentives

Eligibility depends on whether the home meets minimum energy savings requirements. Incentives are determined by the amount of electric savings, fuel savings (natural gas, propane, or oil), and overall performance compared to the program baseline. In addition, participating homes are eligible to receive no-cost LED bulbs.

How it Works

  • Pre-construction Home. During an initial site visit, Mass Save calculates how much energy your home currently uses.
  • Baseline Home. Using advanced software, Mass Save calculates energy savings for both the renovated portion of the home and the new addition.
  • Post-construction Home. Mass Save calculates how much energy your updated home uses.

If your renovation or addition incorporates energy efficiency upgrades, you may qualify for incentives.
