Long-Range Transmission Plan (LRTP)

Project Summary

Approximately two years ago, the Midcontinent Independent System Operator (MISO) initiated a collaborative and innovative effort known as the Long-Range Transmission Plan (LRTP) to provide a roadmap for future transmission investment across the MISO region.  On July 25, 2022, the MISO Board of Directors approved the largest portfolio of long-range transmission projects in Regional Transmission Organization (RTO) history.  The $10.3 billion investment includes 18 transmission projects in MISO’s Midwest Subregion.  The Tranche 1 portfolio is the first of four planned tranches in MISO’s LRTP process.
