NRG Systems announced that Siemens Gamesa Renewable Energy (SGRE) is providing installation support for its Bat Deterrent Systems. The first SGRE-led installation took place in April 2020 at Northland Power’s 100MW Grand Bend Wind Farm in Grand Bend, Ontario, Canada.
SGRE installed Bat Deterrent Systems on six of the site’s 40 Siemens Gamesa wind turbines. In June 2020, Siemens Gamesa installed Bat Deterrent Systems on all eight of the direct drive wind turbines at Auwahi Wind, a 21MW wind farm co-owned by AEP Energy Partners and BP Wind Energy. Auwahi is located on the southeast coast of Maui, Hawaii, where conservation of the endangered Hawaiian hoary bat is particularly pressing.
NRG’s Bat Deterrent Systems use ultrasound to dissuade bats from entering the rotor-swept zone of a turbine. Each system features multiple ultrasound-generating units that are mounted on the nacelle of a turbine, as well as a controller unit for seamless integration into a wind plant’s SCADA system.
