MISO’s Clean Energy Transmission Expansion: Report
Over the last few years, the Midcontinent Independent System Operator (MISO) developed a new plan for a set of lines (known
as Tranche 1) in its region that would enable around 56 gigawatts (GW) of new renewables. This plan was based on scenario modeling of state and utility emissions reduction goals that showed carbon emissions falling by more than 60% in 2040 from 2005 levels. The Tranche 1 portfolio was approved by the MISO Board of Directors on July 25, 2022.
