Green Power
Continuing its leadership role in conservation and environmental stewardship, your electric department is offering three options for clean renewable energy. The energy provided under this program currently comes from equal parts wind, small hydro and landfill gas. All energy supplied through the program will come from sources complying with the renewable energy definition in the Connecticut statutes.
The opportunity to receive green power, to do your part for the environment and to help reduce our dependence on fossil fuels is entirely at your discretion. You may elect to purchase your energy as you do at present or you may select one of the available Green Power options:
- Option Green Power 250 provides 250 KWH of green energy each month for an added cost of $2.50.
- Option Green Power 500 provides 500 KWH of green energy each month for an added cost of $5.00.
- Option Green Power All provides all of your energy requirements for an added cost of one cent per KWH.
