Granby Pumping Plant-Windy Gap Transmission Line Rebuild Project

We need your ideas

Western seeks your comments to help define the issues and alternatives to be analyzed in an Environmental Impact Statement for the proposed Granby Pumping Plant – Windy Gap Transmission Line Rebuild Project.  The public comment period ended Sept. 17, 2007.

About the Granby Pumping Plant-Windy Gap Transmission Line Rebuild Project

Western owns and operates a 12-mile, 69‑kV electric transmission line in Grand County, Colo., that originates at Windy Gap Substation and terminates at Granby Pumping Plant Switchyard. The proposed project would rebuild the single circuit line as a double circuit transmission line and add a second power transformer.

One circuit would replace the existing 69‑kV line; the other circuit would be a new 138‑kV line. Granby Pumping Plant Switchyard would be expanded to accommodate the second line and power transformer. Windy Gap Substation would be modified to accommodate the second line.

This is a joint project between Western, Tri-State Generation and Transmission, Mountain Parks Electric and the Northern Colorado Water Conservancy District. Western initially determined it would prepare an Environmental Assessment for this proposed project in December 2004 and held public open-house scoping meetings on July 28, 2005, and Nov. 15, 2006.  Based on a review of public comments and issues, Western determined to prepare an Environmental Impact Statement for the proposed project.
