MISO’s attempt to justify a new resource accreditation process gave way to heated debate over how to best alleviate the footprint’s reliability challenges.

MISO told stakeholders that it is not yet able to make “quantifiable conclusions” about the amount of capacity available for the 2023-24 planning year.
