Hitchland-Woodward 345 kV Transmission Line

Xcel Energy and Oklahoma Gas and Electric Company (OG&E), are constructing a new 345 kV double circuit transmission line from Xcel Energy’s Hitchland Substation in Hansford County, Texas just north of Gruver, to an OG&E substation near Woodward, Oklahoma. The approximately 120 mile transmission line - a Southwest Power Pool (SPP) Priority Project to increase economic efficiencies and allow wind energy to be transmitted to eastern parts of the SPP - will provide another transmission interconnection point between SPS and the eastern electric transmission grid.

The 345 kV line will be constructed of single pole steel structures. The structures, which are between 80 and 140 feet tall, will require a 150-foot right-of-way and will be spaced 1,000 to 1,300 feet apart. Construction on the project started in April 2013.
