All CapX2020 projects are now complete and energized. The fifth project in South Dakota was placed in-service on September 8, 2017. 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 800 mile, nearly $2 billion investment includes four 345‐kilovolt transmission lines and a 230-kilovolt line. It is the largest development of new transmission in the upper Midwest in 40 years.
