Responding to the needs of the changing energy landscape, the Midcontinent Independent System Operator (MISO), the grid planning organization that includes Michigan, has devoted several years of an intensive, collaborative effort to develop a Long-Range Transmission Plan (LRTP) to build needed high-voltage transmission infrastructure across the region. ITC was actively involved with this process and advocated for the LRTP projects.

• In December 2024, the MISO Board of Directors unanimously approved the largest portfolio of transmission projects in the nation’s history. This includes LRTP Tranche 2.1 – 24 projects totaling 3,631 miles for regional projects in MISO’s Midwest subregion (Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, North Dakota, South Dakota and Wisconsin) and includes a 765kV backbone.
