On April 20, 2020, the U.S. Department of Energy’s (DOE’s) Wind Energy Technologies Office presented the first in a series of live webinars to discuss offshore wind turbine radar interference mitigation strategies and research needs for offshore wind development that may impact sensitive radar systems. The webinar was hosted by the Wind Turbine Radar Interference Mitigation (WTRIM) Working Group—a consortium of federal agencies composed of DOE, the U.S. Department of Defense (DOD), the Federal Aviation Administration, National Oceanic and Atmospheric Administration (NOAA), the Bureau of Ocean Energy Management (BOEM), and the Department of Homeland Security (DHS).

This webinar series is intended to build relationships between key industry stakeholders and agencies around offshore wind-radar issues, share government and industry perspectives on potential impacts of offshore wind on radar missions, and gain a better understanding of the future direction of the offshore wind market.
