Welcome to the
Westchester Power Community
Energy Program
It is the power of community and your participation in the program that helps to make a positive environmental impact. We want to make your journey easier so you can navigate your way through with the different questions or areas of interest.

Westchester Power (Community Choice Aggregation, CCA) is a community-based bulk energy purchasing program designed to control costs and increase the use of renewable energy in Westchester County. Westchester Power is a program initiated and implemented by Sustainable Westchester Inc, on behalf of member municipalities that have chosen to participate in the program.
Sustainable Westchester is a non-profit organization that serves the interests of its member cities, towns and villages. Westchester Power provides residents and small business electric customers a locally chosen alternative to the state-mandated utility—Con Edison or NYSEG—for energy supply. Westchester Power represents the best interests of consumers by providing choices for competitive, fixed prices and cleaner energy.

Mission
To give Westchester County residents better energy choices through collective action that create stable future prices, access clean power at competitive rates, and opportunities for developing local, sustainable energy systems and programs.
Participating Communities
As of 2022, Westchester Power has grown to 29 communities accounting for 145,000 Westchester electric customers, representing 40% of the county residents.
There are three electricity supply groupings:
- Con Edison Municipalities (except for Yonkers): Ardsley, Bedford, Croton-on-Hudson, Dobbs Ferry, Town of Greenburgh, Hastings-on-Hudson, Irvington, Larchmont, Town of Mamaroneck, Village of Mamaroneck, Village of Mount Kisco, New Castle, City of New Rochelle, Town of Ossining, Village of Ossining, City of Peekskill, Village of Pelham, Pleasantville, City of Rye, Rye Brook, Sleepy Hollow, Tarrytown, Tuckahoe, City of White Plains
- NYSEG Municipalities: Bedford, Lewisboro, North Salem, Pound Ridge, Somers
- City of Yonkers
Municipal default supply: Each municipality picks one supply option as the default for the community. Participants can easily change to the other supply, but if no change is requested they are enrolled in the default.
What Can We Do?
Westchester Power:
A Brief Historical Perspective
In February 2015, Sustainable Westchester, a non-profit 501(c)(3) consortium of Westchester County local governments was selected by the New York State Public Service Commission to launch New York State’s first Community Choice Aggregation program (“Order Granting Petition in Part” in Case 14-M-0564, issued February 26, 2015). Community Choice Aggregation (CCA) is an energy procurement program that enables participating communities to join together and purchase electricity in bulk. Purchasing electricity in bulk provides the market clout to negotiate lower rates and to offer credible, clean energy choices for customers.
Community Choice Aggregation is currently available in six US states: California, Illinois, Massachusetts, Ohio, New Jersey and Rhode Island. New York will be the seventh. Over five million customers nationwide are served by a CCA program.
