Casper to Dave Johnston 230-kV Transmission Line Project: Environmental assessment

Technical Report ·
OSTI ID:7242780
Western proposes to reconstruct the existing Casper-Glendo North 115-kV Transmission Line to 230-kV between a point 1.1 miles northeast of the Pacific Power and Light (Pacific) Casper Substation and the Dave Johnston (DJ) Powerplant near Glenrock, Wyoming. As part of the proposed action, Western proposes to remove the portion of the existing Casper-Glendo South 115-kV Transmission Line between Western's Casper Substation and the intersection with the Casper-Glendo North Transmission Line, about 15 miles east of Casper. The removed portion of the Casper-Glendo North Transmission Line would be rebuilt on steel, single-shaft, structures. The section between the point northeast of the Pacific Substation and the intersection with the Casper-Glendo South Transmission Line would be double circuit (230-kV/115-kV). At the intersection of the north and south lines, the new 115-kV section would be tied to the remaining portion of the Casper-Glendo South Line to complete the 115-kV Casper-Glendo circuit. 52 refs.,12 figs., 14 tabs.
