MISO will take a breather from its long-range transmission planning over 2025 to retool the 20-year future scenarios that are the foundation of the transmission portfolios.

MISO members are mulling an advisory vote on whether to support the RTO’s $21.8 billion long-range transmission plan portfolio while tensions simmer over the necessity of the expansion.

MISO Independent Market Monitor David Patton has made a final stand against the RTO’s $21.8 billion long-range transmission plan, while members are advising the MISO Board of Directors that the IMM's opinions on transmission shouldn't hold water.

MISO’s 2024 transmission planning cycle is shaping up to include 459 new projects totaling $6.7 billion.

MISO has multiple planning topics to tackle on the horizon, with work involving an update of merchant HVDC interconnection procedures, making expedited transmission project reviews more manageable, and evaluating co-located load and generation seeking interconnection.

MISO’s 2024 Transmission Expansion Plan increased slightly in cost to $5.8 billion while the Southern Renewable Energy Association requested MISO explore an alternative to an Entergy Texas reliability project.

MISO announced it was unable to land on a suitable substitute for a $260 million Entergy Louisiana reliability project about eight months after it announced an alternatives study.

MISO suggested an approximately $20 billion portfolio for its second long-range transmission planning effort that contains several 765-kV line segments.

MISO's draft 2024 Transmission Expansion Plan calls for $5.5 billion in projects, with the South region again accounting for some of this year’s most expensive projects.

MISO’s Planning Subcommittee will tackle possible modifications to expedited project reviews, the process that allows transmission developers to begin construction earlier than usual.
