Carmel, INDIANA - The $10.3 billion investment includes 18 transmission projects in MISO's Midwest Subregion.

MISO has announced that the MISO Board of Directors unanimously approved a significant portfolio of long-range transmission projects. The $10.3 billion investment includes 18 transmission projects in MISO's Midwest Subregion. This Tranche 1 portfolio is the first of four planned tranches in MISO's Long-Range Transmission Planning (LRTP) process.

According to MISO, these critical projects are needed to begin to integrate new generation resources outlined in MISO member and states plans and increase resiliency in the face of severe weather events. 

"MISO's LRTP process is focused on working collaboratively with our diverse stakeholder community to design the transmission system needed for continued reliable and resilient operations," said Clair Moeller, MISO's President and Chief Operating Officer. "These projects will support the reliable, affordable transition of the generation fleet."

"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."

According to MISO, they used existing transmission corridors to plan this portfolio of projects, reducing the impact on local areas and communities, lowering construction costs, and shortening implementation time.
