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.


AES is proposing to use all the existing sites and support facilities that have already been established for Wethersfield Wind. The existing wind turbine towers will not be replaced or relocated, though the existing foundations may require modifications to accommodate the repower. Where feasible, AES will replace turbine drivetrains, rotors, hubs, and blades. Generators will be either refurbished or replaced based on the condition of the individual generators, and all existing project facilities and points of interconnection will be used as-is. No changes to the project area, number of generators, access roads, or electrical support systems are expected.
