Reliability and quality of service will remain the same. Furthermore, you will continue to have all existing consumer rights and protections.

The City of Pittsfield began exploring the Pittsfield Community Choice Power Supply Program in 2015 to bring the benefits of renewable energy and electricity choice to its residents and businesses. Pittsfield Community Choice Power Supply's goal is to support local renewable energy projects and maximizes consumer protections, all at a price at or below the average price of Basic Service power from the utility. The program is part of Pittsfield’s efforts to promote environmental sustainability. 

This Program - generally called municipal aggregation - enables local governments to combine the purchasing power of its residents and businesses to provide them with an alternative to Eversource Basic Service (M.G.L. c. 164, § 134). The initial program, which tool effect on January 1, 2018, offered residents and small businesses on local electricity utility Eversource's Basic Service rate 25% more solar electricity. 

This Program only affects the supply portion of your monthly bill. It will not affect the delivery portion of your monthly bill. Eversource will continue to deliver your electricity but Pittsfield has chosen the supplier for the Program. NextEra will provide electric power supply for all consumers currently on Basic Service in Pittsfield, and beginning in 2021 it will be Dynagy that will be the energy supplier..


YOU WILL BE AUTOMATICALLY ENROLLED IN THIS PROGRAM unless you choose not to participate and you opt-out.

The aggregation rate will befixed at $0.09603 for 36 months (January 2021to January 2024) while Eversource’s Basic Service rate changes twice a year, in January and July. As a result, the aggregation rate may not always be lower than Eversource’s Basic Service rate. The goal of the aggregation is to deliver savings over the life of the Program against Eversource’s Basic Service rate.

There is NO PENALTY CHARGE TO OPT-OUT of the Program and return to Eversource Basic Service.

IF YOU HAVE BEEN MAILED A NOTIFICATION you do not need to take any action to participate in the Program.

BUDGET PLAN OR ELIGIBLE LOW-INCOME DELIVERY RATE CONSUMERS will continue to receive those benefits from Eversource.

SOLAR PANEL CONSUMERS will continue to receive their net metering credits while benefiting from the aggregation rate.

IF YOU HAVE ALREADY CHOSEN A GREEN POWER SUPPLY OPTION ON YOUR OWN you must opt-out of this Program. This will ensure you continue to get your electricity from that Green Power Supply.

It is possible to choose a competitive electricity supplier to deliver your electricity, but the terms and conditions of cancellation depend on the contract you sign with the competitive supplier. Eversource owns the power lines that delver electricity to your house so they remain your distribution company and continue to bill you. You will simply notice a different supplier (and supply price) on your bill.

Learn more about how competitive supply works on the Commonwealth of Massachusetts website here, and also see this informational document.

If you choose to seek electricity supply from another vendor, we advise residents to thoroughly educate themselves about a competitive supplier before signing a contract.

Many competitive suppliers claim to include renewable energy as part of their energy mix. However, these claims may not always be taken at face value. Often, competitive suppliers can offer a lower rate because they are producing electricity more cheaply, but using a dirtier fuel like coal, and then mixing it with inexpensive renewables like Midwest wind energy. Other suppliers promise renewable energy, but may deliver energy that you might not consider renewable, like biomass. Other suppliers provide renewable electricity through RECs (renewable energy certificates and there is some controversy about whether REC's actually increase the amount of renewables on the grid because, in some areas of the country, wind farms are inexpensive to build and many argue they would be built regardless of RECs. If you are interested in supporting renewable energy generation, see the Mass Energy FAQs

As with all consumer products, you should read contracts carefully. Some rates are month-to-month variable, while other rates are fixed for 6 to 12 months. Often a fixed rate reverts to variable rate after six (6) months unless you sign a new fixed rate contract and companies do not have to notify you that the fixed rate term is ending.

The cheapest and most effective way to save money on your utility bills is to invest in energy efficiency, either on your own or using the Mass Save program.
