WinPower is offered by the Town to provide more electricity supply options and more renewable energy to Winchester residents and businesses. WinPower, doesn’t replace Eversource, the electric utility in Winchester, which continues to deliver electricity, repair outages and manage all electricity billing.

WinPower is the only electricity program offered by our Town – beware of look-alike offers and always look for the Town seal on materials sent to you!

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.
