In 2006, the Town of Wethersfield adopted the "Town of Wethersfield Wind Energy Conversion Device/Farm Licensing, Siting and Design Regulations and Requirements Law.” The law establishes numerous requirements related to setbacks, safety, sound, shadow flicker, wildlife impacts, farming impacts, etc. Wethersfield requires applicants to obtain a license in order to operate the wind farm. This license can be renewed every five years, with fee relating to megawatt capacity.
