Stakeholders want MISO to develop a smaller, congestion-relieving transmission study after this year’s near-term congestion study focused on how best to sequence transmission outages needed for construction of long-range transmission projects.

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 said it will design an expedited resource adequacy study process so generation projects in the interconnection queue that are needed for capacity sufficiency will get grid treatment sooner.

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 announced it will move forward on annual interconnection queue cap based on 50% of peak load for the year in question, this time removing exemptions for projects that regulators deem essential.

MISO is hesitant to grant a request from Michigan to give dispensations to distributed energy resources from its mandated affected studies that gauge transmission system impacts.

Although it’s largely compliant with the directives of FERC’s Order 1920 on regional transmission planning, MISO intends to seek a yearlong extension of the June 2025 compliance deadline.

A band of Michigan utilities wants the option to decline MISO’s affected system-style studies on distributed energy resources.

MISO said after its experience with its first long-range transmission portfolio, it no longer wants to open simple, conductor-only projects to its competitive bidding process.

MISO’s Independent Market Monitor continues to cast doubt on the theoretical benefits estimates of the second long-range transmission projects as the RTO intends to add more projects to the already $17 billion to $23 billion portfolio.
