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 is poised to eliminate its emergency demand response participation option, framing it as a clunky and scarcely used source of emergency assistance.

Load-serving entities that decide against participating in MISO’s capacity auction must secure anywhere from 1.5% to 4.2% beyond their reserve margin requirements in the 2025/26 planning year.

MISO this year said it generally agrees with the six new market recommendations brought forward in its Independent Market Monitor’s annual State of the Market report and is actively working on one of them.

MISO members will likely have to add 343 GW of installed capacity by 2043 to meet policy goals while maintaining resource adequacy, the RTO said in preliminary results from its annual Regional Resource Assessment.

The Southeast’s traditionally risk-averse vertically integrated utilities are now embracing the clean energy transition, driven by economic development in the form of new industry and data centers.

MISO said unless stakeholders can come up with an alternative it hasn’t explored, it will have to renew its sole system support resource — Manitowoc Public Utilities’ Lakefront 9 coal unit — for another year.

Entergy said it can tackle industrial load growth with new solar, carbon capture technology at new and existing gas plants and by possibly bringing new nuclear capacity into the mix.

Xcel Energy is welcoming the coming wave of data centers despite the increased demand they will place on the grid, saying it will accelerate transmission and generation build.

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.
