Long Range Transmission Planning (LRTP) is a key initiative of the Reliability Imperative. The focus of LRTP is to improve the ability to move electricity across the MISO region from where it is generated to where it is needed - reliably and at the lowest possible cost. 

In July of 2022, MISO's Board of Directors unanimously approved $10.3 billion in new transmission projects. This LRTP Tranche 1 Portfolio, is the first of four tranches of transmission solutions developed to provide reliable and economic energy delivery to address future reliability needs. Additional information around this portfolio can be accessed through the navigator block found on the Multi-Value Projects (MVPs) page.
