Stoneham Community Electricity Aggregation (CEA) is an electricity supply program organized by the Town of Stoneham to provide residents and businesses with new, Town-vetted options for electricity supply.  The delivery of electricity and billing for use is still completed through Eversource, so customers continue to receive one bill from the utility.

Renewed through 2023

The town of Stoneham’s electricity aggregation program has been renewed for another three years, providing residents and businesses in our town with stable, competitive electricity prices and an extra 5% renewable energy certificates (MA Class I) through December of 2023. 

Program offerings

Stoneham CEA has a standard product, Stoneham Local Green, which has five percent (5%) more renewable energy than required by state law. Participants in the program will automatically receive Stoneham Local Green unless they chose one of the other optional products.

Stoneham Local Green 5%

Includes 5% more Renewable Energy Certificates (MA Class I RECs), than required by the Commonwealth

Premium Local Green 50%

Includes 50% more Renewable Energy Certificates (MA Class I RECs), than required by the Commonwealth

Premium Local Green 100%

Includes Renewable Energy Certificates (MA Class I RECs) equal to 100% of the user’s electricity consumption, in addition to meeting all renewable energy requirements


Meets all Renewable Energy Certificate requirements

Stoneham CEA pricing will remain fixed and in effect from November 2020 to December 2023. Products described as Green contain renewable electricity above that required by state law. The additional renewable electricity qualifies for MA Class I designation and comes only from solar, wind, anaerobic digestion and low-impact hydro located within New England. Local refers to New England.

Goals of Stoneham’s Community Electricity Aggregation program

Renewed until 2023

Stoneham’s CEA program procures electricity supply contracts when the market is favorable. Combined with the bulk buying power of thousands of households and businesses in the program, Stoneham’s CEA aims to produce savings for customers compared to Eversource’s Basic Service rates, however, savings cannot be guaranteed.

Price Stability

Stoneham CEA contracts for a multi-year, fixed price contract. In contrast, Eversource Basic Service rates change every six months for Residential and Small Commercial customers, and every three months for Large Business customers. However, Stoneham CEA rates may be above or below the Basic Service rate in any given period.

Consumer Protection

Stoneham CEA includes consumer protection-focused terms and conditions such as the ability to leave the program at any time without penalty.

Local Renewable Energy

Stoneham CEA’s standard product includes five percent (5%) more renewable energy certificates (MA Class I), than required. This means you can support the growth of renewable energy resources in New England. There are also two optional products that have even more renewable energy: 50% extra and 100% renewable electricity. Read about the options and sign up.
