Clean Energy Supply

Clean Energy in Brookline Green Electricity

Brookline Green Electricity is committed to supporting the growth of new, local renewable energy in our region. The State of Massachusetts has progressive policies that require everyone to use more renewable energy over time, however, the pace of change needs to be faster to mitigate the worst effects of climate change. Brookline Green Electricity is leveraging the buying power of our community to bring more clean electricity to our residents and businesses. Read on to learn how we’re doing it and the impact we’re having.

A Green Option for Everyone

Brookline’s standard product, Brookline Green, has 30% extra renewable energy included, above and beyond the State requirements. Participating in Brookline Green makes you a climate leader. We also offer optional products that add 65% and 100% clean energy for those that are ready and able to go further.

Buying from New England, Buying Clean

All of the extra renewable energy in the Brookline Green Electricity program qualifies as MA Class I, and it is provided through local non-profit Green Energy Consumers Alliance. This results in two important benefits:

Only New England Sources 

MA Class I renewable energy can come from New England or adjacent parts of Canada and New York. Brookline exclusively sources its extra renewable energy from within New England. We’re helping to keep our energy impact local, supporting New England’s clean energy economy. See below for a map of sources.

Only Zero-Emission or Methane-Destroying Sources

Brookline Green Electricity’s extra renewable electricity only comes from: 

  • Zero emission sources, such as solar, wind, low impact hydropower1; and

  • Sources that destroy methane, such as anaerobic digestion. Methane has a global warming potential (GWP) 28-36 times greater than CO2 over a 100 year period2. Combustion destroys methane and releases some CO2, resulting in a net reduction in GWP.

Other forms of biomass are explicitly not purchased, due to their positive emissions of CO2 during their life cycles.

Green Energy Consumers Alliance, the source for all Brookline Green Electricity’s extra renewable energy, helps bring new renewable projects to life through long-term contracts. The sources from which Green Energy Consumers buys are shown below as of December 2019.

Helping to Build Clean Energy

Massachusetts has a requirement for every energy supply to include a minimum amount of MA Class I renewable energy, and that amount increases each year. If energy suppliers don’t meet those requirements, they pay a penalty. This policy, known as the Renewable Portfolio Standard, provides growing demand for renewable energy, which incentivizes new renewables to be built. By purchasing a significant quantity of extra MA Class I renewable energy, Brookline is raising demand, incentivizing even more renewable energy to be built. 

How big is our impact? According to our energy broker (Good Energy), in 2019, Brookline Green Electricity bought a 36,198 MWh of extra MA Class I renewable energy, above and beyond State requirements. These voluntary purchases are equivalent to the output of the annual production of about 8 typical wind turbines (1.5 MW each). 

We are excited that many other cities and towns are joining with Brookline to implement the same type of program and amplify our impact. In fact, recent estimates suggest that fully 10% of the entire MA Class I REC markets will soon be voluntarily purchased by municipal aggregations going above and beyond state requirements, like Brookline Green Electricity,.

Electricity Supplier: Direct Energy Services

Following a competitive bid to extend the Town’s Brookline Green Electricity program, the Town selected Direct Energy Services (MA DPU Electric License # CS-047) as it’s retail electricity supplier for the 35 month time period of Jan 2020 through Nov 2022.  Direct Energy is the supplier to numerous Community Electricity Aggregation programs in the Commonwealth. Under the program, Eversource Energy continues to deliver the electric supply to households and businesses with no change in the quality of service just as it has since the program launched in 2017. Before the contract ends in November 2022, the Town will go out to bid for a new supplier to obtain competitive supply rates.

Direct Energy Services obtains renewable energy from locally produced 100% non-polluting New England renewable energy from our non-profit partner, Green Energy Consumers Alliance (formerly Mass Energy). The purchase of renewable energy in the form of Massachusetts Class I Renewable Energy Credits (RECs) ensures that NEW renewable energy is added to the ISO-New England power grid. Ensure that the renewable energy you purchase adds NEW renewable energy to the power grid. For more on this topic, read Green Energy’s explanation of the value of MA Class I RECs to avoid greenwashing. Supplier’s contact information: or call 866-968-8065.

Eversource is the utility that continues to deliver electricity from the power grid to your household or business and to maintain the power lines and infrastructure. Contact Eversource to report billing issues, outages, and emergencies.
