Switching your energy supply

Switching to competitive energy

City of Cambridge Community Electricity Aggregation

The City of Cambridge launched the Cambridge Community Electricity program on June 18, 2017 to bring the benefits of renewable energy and electricity choice to its residents and businesses. The program offers residents and small businesses on Eversource's Basic Service rate 25% more solar electricity. Cambridge Community Electricity supports 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 Cambridge's efforts to promote environmental sustainability.

The Community Development Department of the City of Cambridge held a public hearing on June 29, 2016 to receive comments on the City's draft community choice electricity aggregation plan. The City will hold public meetings in June 2017 to educate Basic Service Customers about what Cambridge Community Electricity will mean to them.

Competitive 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.

Risks of Competitive Supply

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.

Eversource has discontinued its green power program and we encourage Cambridge residents to switch to Mass Energy’s Renewable Energy Program.

Confirm that the renewable energy you are buying is in addition to the State of MA RPS mandated amount. Currently, the 2014 RPS Class I requirement is nine percent, and is set to increase by one percent each year. You can verify the type of renewables being sold by your supplier at the Green-e website and compare the fuel mix to Eversource’s

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. Learn more about how to improve your home’s energy efficiency at the Cambridge Energy Alliance website.

Switching to Natural Gas

While not as sustainable as renewable energy resources, cleaner energy can help reduce greenhouse gas emissions. Natural gas produces 27% less carbon dioxide than heating fuel oil and natural gas is generally less expensive. So switching to natural gas is helpful in reducing green house gas emissions though it is not without serious environmental impacts.
