Earlier this week, the Midcontinent Independent System Operator (MISO) Board of Directors unanimously approved the largest portfolio of transmission projects in the nation’s history. The 488 projects span more than 5,000 miles across 15 states in the MISO footprint and include local reliability and growth projects, the Long Range Transmission Planning (LRTP) Tranche 2.1 portfolio of projects, and the Joint Targeted Interconnection Queue (JTIQ) projects with Southwest Power Pool. In total, an over $30 billion portfolio.
The 2024 MISO Transmission Expansion Plan (MTEP) includes the following:
Local Reliability – 459 projects totaling 932 miles to support reliability in all 15 states across the MISO region – 6.7B investment.
LRTP Tranche 2.1 – 24 projects totaling 3,631 miles for regional projects in MISO’s Midwest subregion (Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, North Dakota, South Dakota and Wisconsin) and includes a 765kV backbone – $21.8B portfolio with a cost-to-benefit ratio of 1.8-3.5 with benefits potentially exceeding $72 billion.
JTIQ – five projects totaling 490 miles to enable generation on the MISO/SPP seam (Iowa, Kansas, Minnesota, Missouri, North Dakota and South Dakota). The $1.6B investment is expected to enable 28 GW of new generation.
Powering good!
