MISO Board of Directors unanimously approved a $10.3 billion portfolio of long-range 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. 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. This addendum, which can accessed via the link below, proposes a portfolio of 18 transmission projects located in the MISO Midwest Subregions with a total investment of $10.3 billion, and benefit-to-cost ratios average of 2.6, where benefits well exceed costs. This Tranche 1 portfolio of least-regrets transmission projects will help to ensure a reliable, resilient and cost-effective transmission system as the resource mix continues to change over the next 20 years. The Tranche 1 portfolio, with more than 2,000 miles of transmission line, represents the most complex transmission study efforts in MISO’s history. It is not clear to me whether all or any of these projects will be subject to MISO’s competitive transmission processes.
