The Midcontinent Independent System Operator this week approved a major portfolio of new transmission projects for their system's midwest subregion, a multi-state area that corners the Great Lakes

The $10.3 billion package includes 18 transmission projects, all of which are expected to be connected by the end of the decade. One of the more exciting aspects of this announcement is that the major portfolio of projects is considered "Tranche 1" which means more of these major transmission packages are coming within MISO, which stretches down the spine of the U.S, from the Canadian border around northeast Montana down to the Gulf shores of Louisana. MISO's leadership said as much in a July 25 announcement about the projects. 

“While Tranche 1 represents an important start, further work is needed to ensure reliability,” said Aubrey Johnson, MISO’s vice president of system planning. “Tranche 2 will focus on the MISO Midwest Subregion, Tranche 3 in MISO South, and Tranche 4 will address the limitations on power exchange between the MISO Midwest and South Subregions.”
