Kathryn D. Sullivan Ph.D., Undersecretary of Commerce for Oceans and Atmosphere, sent this response to Nebraska Senator Deb Fischer after Senator Fischer contacted NOAA with concerns pertaining to NextEra's proposed Cottonwood wind energy facility which would site dozens of wind turbines within 2-7 miles of the NEXRAD weather radar in Blue Hill, Nebraska. Senator Fischer's constituents contacted her out of concern for their safety if the weather radar was impaired by the turbines.

NextEra's Cottonwood wind project (113.6 MW) proposes to site all of its 52 turbines within 2 to 7 miles of the Blue Hill, Nebraska NEXRAD radar. This will be the closest of any operating turbines in the U.S. to weather stations in Tornado Alley. The National Weather Service meteorologist-in-charge at the Grand Island/Hastings Weather Forecast Office in Hastings, NE, agreed to sign this letter of intent addressing the times when operational curtailment of the turbines would be required in order to evaluate a storm within the range of the radar. The agreement is in effect for five years from the date it was signed (November 24, 2014). The agreement is entirely voluntary and non-binding on any party. It can be terminated at any time upon notice of just one party. The introduction of the agreement is provided below. The full agreement can be accessed by clicking the link(s) on this page.
