No-cost Home Energy Assessment

SEEN is designed to make energy-efficient upgrades for Somerville homeowners, landlords, and tenants easier and more affordable through the Mass Save® Home Energy Services Program no-cost Home Energy Assessment. If you would like to make your home more energy efficient, energy-efficiency is the generally the most cost-efficient and effective way to start.

An assessment takes about one to three hours. The advisor will provide you with no-cost energy-efficiency upgrades like LED and CFL light bulbs, programmable thermostats, smart power strips, and water saving devices for qualified fixtures.

The advisor will conduct a health and safety check, looking for toxins, hazards, and check the efficiency of your heating system and provide you with a report of their findings and recommendations.

Competitive Electric Supplier Information  

Due to the influx of residents inquiring about purchasing basic electrical service from competitive suppliers, we have compiled the tools and resources available to help residents decide what distribution option is best for them.  This information is for people who have been solicited to switch their basic service provider and is separate from the City’s Community Choice Aggregation program. For more information on the City’s aggregation program, please visit

To help residents decide if sticking with basic supply service, or choosing a competitive supplier, the Department of Public Utilities (DPU) has created Energy Switch Massachusetts, a tool to help residents compare third-party suppliers.

If you are contacted by a competitive supplier about switching basic service providers, you are not required to sign an agreement or contract with that supplier. 

According to the DPU, competitive suppliers may offer:

  • Two pricing structures:
    • Fixed-price: Price remains constant for a specified period of time, but may contain an early termination fee.
    • Variable-price: Price changes frequently, but generally do not have specified terms and early termination fees.
  • Two billing options:
    • Consolidated-bill option: Competitive suppliers use the monthly bill sent by the electric distribution companies.
    • Dual-bill option: Competitive suppliers send a separate bill for supply products.
  • Two pricing options:
    • Six-month fixed‑price option
    • Monthly pricing option (this pricing structure is also available through Eversource)
  • Renewable energy (RE) products:
    • Percent energy mix generated from RE resources
    • Specific locations and characteristics of RE resources
  • Other services and products

8 Steps to Going Solar in Somerville

#1  See if your home is solar ready with Google Project Sunroof.

#2  Educate yourself.

Solar photovoltaics (PV) convert sunlight into electrical energy through solar panels connected to an electrical system, or to the electrical grid. Check our Massachusetts Clean Energy Center How It Works diagram to learn more.

#3  Shop around and select an installer.

Purchasing vs. Leasing

If you are purchasing the system, you will receive full incentive values for the energy your produce through net-metering. The owner should expect to recoup the value of the system between approximately 4-8 years after the system is turned on. Low-interest financing is available for a limited time through the Mass Solar Loan at You may also qualify for a federal tax credit of 30% of the total cost of the system.

If you decide to sign a lease or power-purchase agreement, a customer pays for the solar power system over a period of about 15-30 years, rather than in an up-front payment. Often customers can purchase solar for little or no money down, and often realize energy savings immediately. In a power-purchase agreement, a customer agrees to purchase all the energy from a solar system over a fixed period of time.

#4  Apply for Permits from the City.

View the Solar Permit Checklist and submit permit requests online through CitizenServe. Your installer will typically be the one to do this.

#5  Install the system.


  Schedule a final inspection through the City of Somerville.

Your installer will typically be the one to do this.

#7  Request permission to operate from the utility (Eversource)

#8  Your system is interconnected!

Congratulations! You are now solar powered.☺


Multi-family & Condo Resources

Financial Incentives:

  • Federal Tax Credit: A 30% Federal Investment Tax Credit (ITC) is available for qualified residential and commercial projects. A guide for how the ITC works can be found at
  • Limited time Mass Solar Loan: Residential, Business, and Low-Income low-interest financing is available through the Mass Solar Loan at View the program’s Performance and Comparison Tool.
  • Five-year Modified Accelerated Cost Recovery System (MACRS): Business owners can depreciate solar electric systems over a five-year schedule.
  • Business Energy ITC: A sliding tax credit that varies depending on the scale and date of the energy retrofit. Visit the U.S. Department of Energy website to learn more.
  • Net metering: Net metering is a policy that allows homeowners to receive retail value for the electricity that their solar energy system produces. The term net metering refers to the method of accounting for the PV system's electricity production. Net metering allows homeowners with PV systems to use any excess electricity they produce to offset their electric bill. As the homeowner's PV system produces electricity, the kilowatts are first used for any electric appliances in the home. If the PV system produces more electricity than the homeowner needs, the extra kilowatts are fed into the utility grid.
  • Solar renewable energy certificates (SRECs): SRECs show that a certain amount of electricity was produced using solar energy. One is created for every megawatt hour (MWh) of electricity produced by a solar generator. SRECs are sold separately from the electricity they produce.
  • Other financing resources can be found at the Database of State Incentives for Renewables and Efficiency (DSIRE) and the MassCEC’s Financing Clean Energy Projects page.
  • Department of Energy Resources (DOER) Solar Massachusetts Renewable Target (SMART) Program:

    Please be aware the DOER is in the process of restructuring state-wide incentives for solar to create a long-term sustainable incentive program to promote cost-effective solar development. This policy is expected to shift from the current SREC model to a declining block grant model.

    The DOER has hosted several stakeholder meetings and public commenting periods to help create the new policy. The City of Somerville submitted a joint-comment with the City of Cambridge advocating for a smooth transition from SREC II, additional incentives for multifamily properties, and stressing the importance of low-income and community solar projects.

    As of June 2017, the SMART program has not been finalized and a start date has not been set. Please see the DOER’s website for more information.

2016-2017 National Grid Community Initiative

Thanks to resident participation in the 2017 National Grid Community Initiative, Somerville has secured grant funding for future energy programs. Residents that completed Mass Save® no-cost Home Energy Assessments and subsequent energy upgrades helped Somerville reach goals set by National Grid. This was the second consecutive year Somerville participated in the Initiative.

Between 2016 and 2017, Somerville residents completed 1,600+ assessments and 1,200+ energy upgrades, reducing greenhouse gas emissions equivalent to taking nearly 900+ passenger cars off the road for one year. Residents saved more than $1.1 million and the City earned a reusable water bottle station as part of the Shining Community Award, as well as grant funding for future energy initiatives.


The City of Somerville has earned SolSmart Gold Designation from SolSmart, a national designation and technical assistance program funded by the U.S. Department of Energy SunShot Initiative. Launched in April 2016, SolSmart aims to designate 300 communities during the three-year, federally funded program.

SolSmart nationally recognizes communities for adopting programs and practices that make it faster, easier, and cheaper to go solar. A SolSmart designation is a signal that the community is “open for solar business,” helping to attract solar industry investment and generate economic development and local jobs. Earlier this year, Somerville became the first community in the Commonwealth to be designated Bronze. Somerville is now the first community in Massachusetts to earn Gold.

To achieve designation, cities, and counties take steps to reduce solar “soft costs,” which are non-hardware costs that can increase the time and money it takes to install a solar energy system. Soft costs now represent roughly two-thirds of the total price of an installed residential system. Reducing these costs leads to savings that are passed on to consumers.

Solarize Somerville 2016

Thank you to all those who participated in Solarize Somerville. Solarize Somerville was a limited-time incentive program the City of Somerville offered in partnership with the Mass Clean Energy Center and the Department of Energy Resources. The program lasted July-December 2016. Solarize Somerville surpassed its goal of 100 signups with 115 residents committing to installing solar arrays. Together, the solar arrays will produce more than half a megawatt of electricity, which also exceeds the Solarize solar capacity goal the city team set of signing up enough residents to produce 400 kW.

Solarize Somerville Final Program Total: 569 kW. Thank you! We topped our 400 kW goal by 42%!
