Wethersfield Wind, located in the Town of Wethersfield and Town of Eagle in Wyoming County, New York, is an existing 126 MW wind park planned to be repowered by AES. This project reduces carbon dioxide emissions by an estimated 183,833 metric tons each year, producing enough electricity to power approximately 33,400 homes annually.


Operational since 2009, Wethersfield Wind is a project to which AES is excited to bring new life. The repowering of the wind park will incorporate significant component and control systems replacement with design improvements, resulting in greater energy production and improved energy reliability and availability. Repowering will ensure continued, significant economic benefits to the local community via HCA (Host Community Agreements) and PILOT (Payments in Lieu of Taxes) agreements.
