Clean Energy Technologies

A number of clean, efficient technologies can help Massachusetts homeowners save money on their heating, cooling, and electricity bills while protecting the environment and maintaining a high level of comfort. These technologies include the following:

  • Clean Heating & Cooling: Air-source heat pumps (including cold-climate mini splits) and ground-source heat pumps provide efficient heating and cooling and can save money on heating and cooling costs. They can also reduce the greenhouse gas emissions associated with heating or cooling, and provide an alternative to electric resistance heat (i.e., electric baseboard), oil, propane, or other fossil-fuel powered heating/cooling.
  • Hot Water: Heat pump water heaters and solar hot water systems can reduce water heating costs and greenhouse gas emissions associated with water heating.They provide an alternative to electric or fossil fuel (oil, natural gas, or propane) hot water systems.
  • Solar Photovoltaic (PV): Solar PV systems use sunlight to produce electricity and can PV systems can be installed and connected to the building’s electrical system to meet on-site electricity demands.Solar PV can be paired with energy storage to capture “excess” electricity so that it can be used at times when the PV system cannot produce enough to meet the immediate electricity needs for the home (e.g. at night.).
  • Energy Storage: Battery technology stores electricity generated from the grid or from accompanying renewable sources (e.g., solar PV systems).The stored electricity is then available to be discharged at a later time to meet on-site electricity demands or demands from the grid. Battery storage paired with on-site solar can help ensure that electricity produced by an on-site solar PV system is fully utilized by the home/building at the site.Battery owners can earn incentives for reducing the load on the grid during peak times by participating in an active demand management program, which allows their electric utility provider to draw energy stored in the battery during times of peak electricity demand to help balance out the electric grid and avoid the use of energy from “peaker plants.”
  • Electric VehiclesThere are a variety of different electric vehicle technologies on the market. The most common include plug-in hybrid vehicles (PHEV), battery electric vehicles (BEVs), and fuel cell electric vehicles (FCEV). Plug-in hybrid vehicles use both an electric motor, powered by a battery and an internal combustion engine that runs on gasoline, and can be plugged in to an electrical outlet to recharge. Battery electric vehicles use an electric motor powered by a battery, and fuel cell electric vehicles use a fuel cell, instead of a battery (or in combination with a battery or supercapacitor), to power an electric motor.

There are several programs, including programs through Mass Save, the Massachusetts Department of Energy Resources, and the Massachusetts Clean Energy Center (MassCEC) that offer incentives to help residents access clean energy technologies. In many cases, incentives from different programs can be combined to help make clean energy technologies more financially feasible.

Note: Rebate, incentive, and financing  programs are not available to all MLP customers. If you are served by an MLP, be sure to verify your eligibility for the program before applying.

Solar Photovoltaic (PV)
Solar Massachusetts Renewable Target (SMART)
  • The Massachusetts Department of Energy Resources (DOER)’s SMART program provides incentives for solar PV installation throughout the Commonwealth. Upon application approval, the incentive is paid by the utility to the system owner
    based on the amount of electricity generated by the system.
  • Increased incentives are available for solar projects that serve low-income customers, provide community shared solar, or are coupled with energy storage.
  • Financing for solar PV on 1-4 unit properties is available through the .
  • To get started, visit MassCEC and learn more about the costs of solar systems and performance, find an installer, and see other resources.
Mass Solar Loan
  • The Mass Solar Loan program matches property owners of 1-4 unit homes to solar installers and lenders that offer low-interest loans for solar projects.
  • Low-income customers are eligible for reduced interest rates and additional incentives to reduce loan principal. Residents with low credit scores are encouraged to apply. Eligibility criteria are listed on the program website.
  • To get started, review the guide on the Mass Solar Loan website and receive a price quote from a pre-qualified installer.
MLP Solar Program
  • The MLP Solar Program offers rebates for solar PV systems in select MLP service territories. Installations of 25 kW or less are eligible for rebates of $1.20 per watt, up to 50% of system costs. More information is available on the program webpage.
  • To get started, review the eligibility criteria and contact your municipality or energy program provider to confirm that your MLP still has funding available before submitting a program application.
Energy Storage
