Wind project developers in the US through May have proposed turbine heights up to a record 207 metres (680 feet) versus an average 146 meters for 2018 installations, as the industry benefits from technology advances, according to a new Department of Energy (DOE) report.
Permit applications filed with the Federal Aviation Administration (FAA) this year show 44% of proposed turbines will exceed 152.4 meters in height (from ground to blade tip extended directly overhead), up from 39% in 2018 and 14% in 2017.
