MISO's sprawling, long-range transmission portfolio now stands at $10.4 billion.

MISO's Board Week touched on its 2021 Transmission Expansion Plan, long-range transmission portfolio and a joint study with SPP intended to build transmission.

MISO's 339-project, $3.04 billion MTEP 21 is headed for approvals from the MISO Board of Directors. 

MISO acknowledged this week that a December approval for its first long-range transmission projects is out of reach and must wait until early spring.

MISO execs say long-term transmission and a capacity market redesign are a must in response to rising climate risks and fleet change.

MISO's annual transmission spending is set to fall after two years of robust investment. 

MISO unveiled a first look at possible long-range transmission projects, igniting testy exchanges between stakeholders over the necessity of grid expansion.

MISO is seeking ways to modify its annual transmission plan and make it easier for stakeholders to suggest alternatives to TOs’ project proposals.

The cost of MISO’s 2021 Transmission Expansion Plan is set to ring in substantially below last year’s spending level, the RTO said at a planning meeting.

MISO is sticking with its usual slate of transmission planning studies for 2021, opting not to include specially targeted analyses in MTEP 21
