CapX2020 is a joint initiative of 11 transmission owning utilities in Minnesota, North Dakota, South Dakota, and Wisconsin formed to upgrade and expand the electric transmission grid to ensure continued reliable and affordable service. The CapX2020 projects provide needed transmission capacity to support new generation outlet, including renewable energy. The projects include four 345 kV transmission lines and one 230 kV line. This is the largest development of new transmission in the upper Midwest in nearly 40 years. The CapX2020 lines are projected to cost more than $2 billion and cover nearly 800 miles.
