Helicopter to scan transmission system

FORT COLLINS, Colo., July 23, 2020 – Platte River Power Authority will use a low-flying
helicopter to conduct an infrared scan of its electrical substations and transmission lines from
approximately 8:00 a.m. until late afternoon of July 27. The purpose of the scan is to help
ensure a continued high level of electrical service reliability by checking equipment for hot spots
or potential defects that require preventative maintenance. Transmission lines will also be
checked for adequate clearance from the ground, objects and vegetation.

This activity will involve more than 250 miles of high voltage transmission lines and more than
twenty substations along the Front Range corridor, from the Rawhide Energy Station north of
Fort Collins to southern Longmont. No set times have been scheduled to fly over specific areas.
