WinPower is our Town’s electricity supply program launched in 2017. The Program provides a range of electricity supply options including WinPower100, which provides 100% clean energy to residents and businesses. If you receive a letter from the Program, you are likely a newly eligible customer. The Town is excited for you to join! Please contact us if you have any questions.

At a time when energy rates are increasing, WinPower provides program participants in Winchester with competitive, fixed rates that will not change for the duration of the term, December 2024 – December 2027. Savings cannot be guaranteed because future Eversource Basic Service rates are unknown.

WinPower is offered by the town of Winchester to provide more electricity supply options and more renewable energy to Winchester residents and businesses. WinPower doesn’t replace Eversource, the electric utility serving Winchester. Eversource continues to maintain distribution lines, service, and billing, so all WinPower customers still receive a bill from Eversource, with the Supplier listed as “Direct Energy – Town of Winchester”.

WinPower is the only electricity program offered by the town of Winchester. Beware of look-alike offers and always look for the town seal on materials you receive.

More Ways to Save! In addition to the supply options through the program, discounts are available for low income customers and customers with heat pumps. Learn more below.

WinPower Electricity Products

WinPower’s default option, WinPower Standard, has more renewable electricity than required by Massachusetts law. Participants in the Program receive WinPower Standard unless they affirmatively choose one of the other electricity options, including WinPower100, which delivers 100% clean electricity.

Future savings compared to Eversource Basic Service cannot be guaranteed because Eversource supply rates change every six months for residential and commercial customers and every three months for industrial customers.

Please note: Customers that opt-out of the program and then seek to re-join, as well as new medium, large and very large business customers joining the program, may be offered a market price, rather than the program price shown in the table above. Such market price will be offered by the electricity supplier in writing, and you will not be enrolled in that price unless you affirmatively accept. The market price will be based on current  wholesale prices and the supplier’s costs at the time the you seek to enroll, and the price will be fixed for the remainder of the Town’s contract with the supplier. At the start of the Town’s next supply contract, you will be transferred to the then-current program pricing.

WinPower Performance

Since the town of Winchester launched the WinPower Program in July 2017, the Program has delivered price stability to Winchester residents through low and consistent electricity rates. Since its start, WinPower has collectively saved residents millions of dollars in lower electricity costs. This strong performance compared to Eversource Basic Service rates has earned WinPower an 85% participation rate. Future savings cannot be guaranteed because future Eversource Basic Service rates are unknown. Best of all, WinPower accomplished this while including more renewable energy in your electricity than Eversource Basic Service.
