CapX2020: Ensuring electric reliability in South Dakota and the surrounding region

Xcel Energy is a partner in CapX2020, a joint initiative of 11 transmission-owning utilities in South Dakota and surrounding states. Its purpose is to expand the electric transmission grid to ensure customers continue to receive reliable, low-cost electricity. It also will increase access to renewable energy sources. The CapX2020 projects include four 345-kilovolt (kV) transmission lines, one 230-kV line and associated substations. The lines represent one of the largest single transmission initiatives in the region in decades, spanning nearly 800 miles.

Sioux Falls Northern Loop Project

Construction is underway on the Sioux Falls Northern Loop transmission line project in Sioux Falls, S.D. and is expected to be complete in April, 2016. Crews are rebuilding 8 miles of Xcel Energy’s 69 kilovolt (kV) system to 115 kV in the northern half of the city between the West Sioux Falls (WSF) and Split Rock (SPK) substations. The project also includes building the new Falls (FLS) substation that will be located in the center of the rebuilt transmission line on Weber Avenue, across the road from the John Morrell meat processing plant, and making upgrades to the existing West Sioux Falls (WSF) and Split Rock (SPK) substations.
