MISO’s Board of Directors is expected to approve a massive portfolio of regional transmission projects on Dec. 12 to keep energy prices low for consumers and ensure system reliability. The 24 proposed high-voltage transmission lines are projected to deliver at least $23.1 billion in net benefits over the first 20 years in service. These lines will help accommodate new electricity generation to meet demand growth at a lower cost and improve reliability during increasingly frequent severe weather events. The portfolio, Tranche 2.1 of the region’s Long Range Transmission Planning process, builds upon the 18 projects MISO approved in 2022 (Tranche 1).

Join the American Council on Renewable Energy (ACORE) for a webinar featuring Midwest grid experts to discuss the benefits of MISO’s second portfolio, how MISO succeeded in reaching consensus on such a historic build, and key takeaways other regions should consider as they seek to comply with the Federal Energy Regulatory Commission’s regional transmission planning and cost allocation rule, Order 1920.
