MA Class I renewables come from new, regional sources (i.e., generation located within, or delivered to, New England, built after 1997). For details on all required renewable resources, see www.mass.gov/service-details/program-summaries.
Additional Product Details
From December 2024 through December 2027 meter read the program appears on utility bill as “Brookline Green Electricity-Direct”.
Prices for all program options in the Brookline Green Electricity Program include a 0.1 ¢/kWh administration fee. Program prices could increase as a result of a change in law that results in a direct, material increase in costs during the term of the electricity supply agreement. Program prices apply only to the electricity supply portion of your Eversource electric bill. Delivery charges on your Eversource electric bill are not affected by the Brookline Program.
Future savings against Eversource’s fixed Basic Service rate cannot be guaranteed because Eversource’s rates change every six months for residential and commercial customers and every three months for industrial customers. For Commercial and Industrial Eversource Basic Service Rates please check out the Eversource supply rates page.
If you participate in Brookline’s program, you will be automatically enrolled at a new price at the end of the contract term unless you inform the Town otherwise. The new price may be higher or lower than the existing price, and the voluntary renewable energy content may change. The Town will contact you no later than 30 days before each automatic renewal to notify you of your supply options.
Sourcing the Additional Renewable Energy
All of the extra renewable electricity in the BGE Program qualifies as MA Class I, and is provided through the local non-profit, Green Energy Consumers Alliance. Purchasing through Green Energy Consumers Alliance provides multiple benefits for our renewable energy.
Tax Deductible
As a federally recognized non-profit, the value of the renewable energy from Green Energy Consumers Alliance is tax deductible, for those that itemize on tax returns.
From New England
MA Class I renewable energy can come from New England or adjacent parts of Canada and New York. BGE sources its extra renewable energy exclusively from within New England. We’re helping to keep our energy impact local, supporting New England’s clean energy economy.
Zero-Emission or Methane-Destroying Sources
BGE’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.
Community Shared Solar (CSS)
There has been a lot of interest in the community in the shared solar projects that are being marketed around Brookline and in Massachusetts in general. We’ve put together a flyer explaining the nuances of the interaction between Community Shared Solar programs and Brookline Green Electricity.
CSS, in most instances, is approved under the Massachusetts’ SMART Program, which provides incentives for solar development in the State. As of July 1, 2025 the state of Massachusetts reports that the following companies have a Community Shared Solar or Low-Income Community Shared Solar project in operation under the SMART Program. Updates and additional detail can be found at: www.mass.gov/doc/smart-solar-tariff-generation-units.
Aquantum Solutions, BlueWave, Clearway Energy Group, Consolidated Edison Development, Key Solar, Lodestar Energy, Madison Energy Investments, MassAmerican Energy, My Generation Energy, Nexamp, NextGrid, Resonant Energy, SunRaise Investments, Sunwealth, Syncarpha, Team Solar and Wales Solar.
