The Midwest Portfolio consists of nine new transmission line projects in Iowa, Wisconsin, Illinois, Indiana and Ohio. These projects fill gaps in the existing transmission grid, improve electric system reliability and market efficiency, provide economic benefits to local utilities and enable increased delivery of high-quality renewable resources.
The Midwest Portfolio projects represent strategic solutions that relieve congestion on the grid, provide operational flexibility to enhance system reliability and deliver economic and market benefits. Some are stand-alone projects, and some work in conjunction with MISO’s multi-value projects and other DATC projects.
DATC will submit these projects to MISO for inclusion in the Midwest Transmission Expansion Plan; a subset of these projects will be submitted to PJM’s Regional Transmission Expansion Plan. The projects would be constructed in phases over the next 10 years, with certain projects serving as prerequisites for others.
