Xcel Energy (NYSE:XEL) said that its estimated 35.5-mile, 161/69-kV Couderay-Osprey transmission line project in Wisconsin went into service on Nov. 22.
Construction began in 2014 on the estimated $50m project, which included rebuilding an aging transmission line that connects the Couderay substation in Sawyer County with the Osprey substation in Rusk County, the company said on its website. The project consisted of replacing the existing two-pole wood structures with single-pole steel structures, Xcel said.
The Public Service Commission of Wisconsin in October 2012 approved a certificate of authority for the project, which is designed to meet the area’s growing electricity needs, support additional load growth, and strengthen electric reliability, the company said.
Also in Wisconsin, work continues on the estimated 180-mile La Crosse-Madison Transmission Line Project, also known as the Badger Coulee Project.
The company added on its website that the estimated $580m, 345-kV line, which runs from north of the La Crosse area to northern Dane County, Wis., is estimated to be in service in 2018.
The line is designed to provide economic savings and support renewable energy policy, as well as to address electric system reliability issues to benefit western Wisconsin communities, the state of Wisconsin and the Midwest region, Xcel said.
Xcel and American Transmission Company – which jointly developed the project – in October 2013 filed an application for the project with Wisconsin regulators, who approved the application in April 2015, Xcel said.
Project construction began this year, starting at the southern end of the project – the Cardinal substation in Dane County – and will continue to the Briggs Road substation in La Crosse County by the end of 2018, the company said.
