Basic Electric Service Disclosure Label

Electric Power Suppliers are required by the Department of Public Utilities (DPU) to provide customers with a disclosure label. The label enables consumers to look at the energy sources, air emissions and information about the supplier in order to make a more informed choice of a power supplier. Consumers can compare energy labels to make the best choice based on their energy needs.

Cape Light Compact Green Information

Electric Power Suppliers are required by the Department of Public Utilities (DPU) to provide customers with a disclosure label. The label excludes information pertaining to the purchase of renewable energy certificates (RECs). Because most wholesale energy transactions do not include information on the source of the energy. RECs are used in New England to track the source of energy generation. RECs are also used for complying with the MA renewable portfolio standard (RPS), which sets requirements for the inclusion of renewable energy delivered in New England.

Benefits of Cape Light Compact Green

SUPPORT NEW RENEWABLE ENERGY-25% of the renewable energy sources in our green program are “new” (built after 1997). Supporting new resources is the best way to drive development of future renewable energy projects.

SUPPORT LOCAL RENEWABLE ENERGY – Our program includes renewable energy from photovoltaic (PV) systems on rooftops across Cape Cod, small hydro facilities from across New England, and landfill gas from a closed landfill in Chicopee, MA. Over time, it is the Compact’s intention to incorporate wind from land-based projects in Massachusetts, particularly those in Cape Cod and Martha’s Vineyard towns.

A CHOICE THAT BENEFITS YOU AND YOUR COMMUNITY – When you pay a premium for Cape Light Compact Green, 100% of the premium you pay is deductible from your federal income taxes if you itemize. The premium is the difference between the price of the Cape Light Compact Green and the price for Cape Light Compact basic energy service.
