STATE OF MINNESOTA PUBLIC UTILITIES COMMISSION July 3, 2017 Nancy Lange, Chair Dan Lipschultz, Vice-Chair John Tuma, Commissioner Matt Schuerger, Commissioner Katie Sieben, Commissioner In the Matter of the Application of Freeborn Wind Farm, LLC for a Large Wind Energy Conversion System Site Permit for the 84 MW Freeborn Wind Farm in Freeborn County. PUC Docket Number: IP-6946/WS-17-410 Honorable Commissioners, I have reviewed the site permit application and wish to draw the Commission’s attention to the following representation made by Invenergy in their application.

8.5.5.2 states in part "construction of wind turbines has the potential to impact TV reception"

KAAL-TV has also expressed their concerns. Please consider this as an incomplete task on the part of Invenergy.

I request that the Commission reject the site permit application until Invenergy provides accurate and complete information.

Sincerely,

Allie Olson 12225 810th Ave Glenville, Mn 56036

PUC Docket Number: IP-6946/WS-17-410 Honorable Commissioners, 8.5.5.2 states 'construction of wind turbines has the potential to impact TV reception' This is from Bent Tree Wind farm: OES EFP Staff Question No. 6 Considering that the conversion to digital TV signals was expected to result in less RF/TV Interference from wind turbines than analog signals, what factors, if known, are the primary sources of RF/TV Interference? WPL RESPONSE

Author: Robert Kreger, Senior Engineer – Telecommunications Office WPL believes the rotation of wind turbine blades may potentially cause television signals to scatter. An antenna receives the intended signal as well as the scattered signal. TV receiver technology and current A/53: ATSC Digital Television Standard from the Advanced Television Standards Committee fail to handle multipath signals adequately. I request that the Commission reject the site permit application until Invenergy provides accurate and complete information.

Sincerely, Allie Olson 12225 810th Ave Glenville, MN 56036
