Daniels Park to Prairie to Greenwood Transmission Project
Overview
We are upgrading approximately 9 miles of existing 230 kilovolt overhead electric transmission line in Douglas and Arapahoe counties, Colorado. Work will occur between the existing Daniels Park Substation (Monarch Boulevard, north of Serena Drive, Denver), Prairie Substation (Timberline Road, east of Mountain Brush Circle, Littleton), and Greenwood Substation (South Holly Street and East Weaver Avenue, Centennial). Additional upgrades are being made to associated equipment at the substation.
This project is part of the larger Denver Metro Transmission Upgrades to upgrade the existing electric system to support new power generation sources and meet future electricity needs.
