No Time To Waste In Filing for Transmission Rate Incentives
The Midcontinent Independent System Operator (MISO) is undergoing the most ambitious transmission expansion in its history. This process, called Long-Range Transmission Planning (LRTP), consists of four project portfolios, or tranches. In July 2022, the MISO Board of Directors approved the first tranche of transmission solutions developed to provide reliable and economic energy delivery to address future reliability needs. Tranche 1 includes 18 projects, also referred to as LRTPs, with an estimated cost of $10.3 billion. These 18 projects are in the MISO Midwest Subregion and include more than 2,000 miles of transmission lines.
