WESTCHESTER POWER COMMUNITY ENERGY PROGRAM - INFORMATION ABOUT NEXT TERM STARTING DECEMBER 1, 2025 This information is for eligible residents and small businesses in Hastings, Dobbs Ferry, Ardsley, Irvington, Tarrytown, Town of Greenburgh, Sleepy Hollow, Tuckahoe, White Plains, Village of Pelham, New Rochelle, Larchmont, Town of Mamaroneck, City of Rye, Rye Brook and Pleasantville. Westchester Power is a Community Choice Aggregation program administered by local non-profit Sustainable Westchester on behalf of participating communities. Westchester Power is the municipally selected default electricity supply option for these communities. It offers competitive, fixed rates for clean and renewable electricity as an alternative to variably-priced and fossil-fuel-based supply of the local utility. Westchester Power is an "opt-out" program, meaning eligible participants must elect to opt out of enrollment into the program if they do not want to participate. Customers always retain the ability to select between our offered renewable energy choices, opt out, or opt back in at any point without fees or penalties. To ensure the availability of a reliable fixed rate option for clean energy in these uncertain times, program electric supply for the next term has been bid out and awarded. Opt out letters will be mailed out in October. Opt out periods for the municipalities are as follows: Oct 16 - Nov 15: Tarrytown, Sleepy Hollow Oct 17 - Nov 16: New Rochelle, Rye Brook, White Plains Oct 18 - Nov 17: Town of Greenburgh Oct 20 - Nov 19: Hastings, Dobbs Ferry, Ardsley, Irvington Oct 23 - Nov 22: Town of Mamaroneck, Larchmont Oct 24 - Nov 23: City of Rye Oct 25 - Nov 24: Pleasantville Oct 30 - Nov 29: Tuckahoe, Village of Pelham New Program Rates and Terms (Residential & Small Business) 24-Month Term Starting December 1, 2025 (Effective 12/1/2025 – 11/30/2027) Residential Rates: 50% Renewable: 11.810¢/kWh 100% Renewable: 12.260 ¢/kWh Small Business Rates: 50% Renewable: 11.700 ¢/kWh 100% Renewable: 12.150 ¢/kWh Con Edison average for the period 7/2024 to 6/2025 Residential: 10.888 ¢/kWh Small Commercial: 10.336 ¢/kWh Additional Information: Program supplier: Constellation NewEnergy Default product: Greenburgh and Pleasantville default supply is 50% Renewable, all other municipalities included in this program update default to the 100% supply.
