WinPower is the Town of Winchester’s program to provide more electricity supply options and more renewable energy to Winchester residents and businesses. With WinPower, Eversource continues to deliver electricity and manage all electricity billing. The only change is the source and cost of electricity supply, chosen by the Town of Winchester.

WinPower Electricity Products

WinPower has a default option, called WinPower Standard, which has 10% more renewable electricity than required by state law. Most participants in the program receive WinPower Standard unless they affirmatively choose one of the other electricity options.

Please note: Prices for all products in the WinPower program include a $0.001 /kWh administration fee. Program prices could increase as a result of a change in law that results in a direct, material increase in costs during the term of the electricity supply agreement. Program prices apply only to the electricity supply portion of your Eversource electric bill. Delivery charges on your Eversource electric bill are not affected by the WinPower program.

WinPower Performance

In July of 2017, the Town of Winchester launched WinPower. First and foremost, WinPower promised to provide price stability when compared to Eversource Basic Service rates. This stability has resulted in an amazing 85% participation rate. WinPower also hoped to generate savings for residents. The program has performed very well so far, however, future savings cannot be guaranteed because future Basic Service are unknown. Best of all, we accomplished this all while including more local renewable energy in our electricity than Basic Service!

How to Participate in the WinPower program

Most residents and businesses in Winchester already participate in the WinPower program. Check your electricity bill to see if you’re one of them: the Supplier should be listed as Dynegy – Winchester. If Eversource is still listed as your supplier, you may complete the enrollment form to sign up for WinPower. If a different supplier is listed, contact that supplier to check for penalties or termination fees that they may charge before you join the WinPower program.

Participation in the WinPower program is voluntary: you can leave the program at any time without fee or penalty.

The program will periodically send Customer Notification letters to new or newly eligible electricity customers, which includes the program details, information about product prices, and renewable energy certificates. Customers who receive this letter and do not choose to opt out will be automatically enrolled. To enroll sooner, use our online forms.
