City goals for the program
The Cambridge Community Electricity Program was designed to encourage the development of new renewable energy projects in Cambridge and New England. The program directly supported the development of a new solar energy project in Cambridge.
Add renewable energy in Cambridge
Both the Standard Green price and the 100% Green Plus price include a small additional charge of 0.2 ¢/kWh. The City used the money collected from this additional charge to fund the development of a new solar energy project. The result is that each Cambridge Community Electricity Program participant will help to add more renewable electricity to the local electricity grid. The electricity produced by this new solar project will take the place of some fossil fuel-generated electricity.
The City will apply the renewable energy certificates (RECs) generated by this new solar project to a portion of the electricity used by both Standard Green and 100% Green Plus participants. As a result:
- Standard Green participants will receive the minimum amount of renewable energy required by the state, all from projects in New England. They will also receive additional renewable electricity from the new solar project, over and above the state-required minimum.
- 100% Green Plus participants will receive 100% renewable energy, all from projects in New England by having 100% Massachusetts Class I RECs purchased on their behalf. They will also receive additional renewable energy from the new solar project.
Renewable energy is purchased through renewable energy certificates, or RECs. Visit this page to learn about RECs.
Support renewable energy throughout New England
Through the program, the City also makes it possible to do more. Program participants may choose to opt up to the 100% Green Plus option and receive 100% renewable electricity from renewable energy projects in New England (MA Class I RECs), as well as receiving additional renewable electricity from the new Cambridge solar project. 100% Green Plus participants are supporting the development of additional renewable energy throughout New England by:
- purchasing RECs that match 100% of their electricity usage from existing renewable energy projects in New England (MA Class I RECs). The purchase of additional RECs, over and above the minimum required by the state of Massachusetts, helps to create a stronger market for renewable energy generated by renewable energy projects in New England.
- having contributed 0.2 ¢/kWh to the development of the new solar project in Cambridge, which will apply additional RECs from that project to their electricity use, just like participants in Standard Green. The contribution to the new solar project brings new renewable energy to the grid and can help displace fossil fuel-power production.
The 100% Green Plus option includes energy produced by a range of renewable energy projects. The majority is wind energy, but it could also include solar energy and energy produced by anaerobic digestion, biomass, and landfill gas.
