Wind Farm Study Would Assess Mitigation Options for Weather Radar, DOD Operations

The conference report to the fiscal 2019 defense authorization bill directs DOD to work with the National Oceanic and Atmospheric Administration (NOAA) to study the impact of wind farms on weather radar and military operations. The study, due to Congress one year after the legislation is signed into law, would focus on improving existing tools needed to validate mitigation options for weather radar, according to section 318. The study should include:

  • potential impacts of wind farms on NEXRAD radar and other weather radar used by DOD, NOAA and the National Weather Service (NWS);
  • recommendations to reduce or mitigate the potential impacts;
  • recommendations for addressing impacts to NEXRAD and other radar from increasing turbine heights;
  • recommendations to ensure wind farms do not harm the ability of NOAA and NWS to forecast hazardous weather;
  • the cumulative impact of multiple wind farms near a single radar on the ability of NOAA and NWS to forecast hazardous weather;
  • an analysis of whether various characteristics of a wind farm — including layout, turbine orientation, number or density of turbines, proximity to radar or turbine height — result in greater impacts to the missions of DOD, NOAA and NWS, and if so, how those projects can be better sited to reduce NEXRAD impacts;
  • case studies in which DOD, NWS and industry collaborated to implement solutions; and
  • mitigation options, including software and hardware upgrades, which NOAA and NWS have researched and analyzed.
