MISO is determined to file with FERC by the end of March to introduce a probabilistic capacity accreditation that’s controversial among its stakeholders.

MISO said it has landed on a final design in its quest to move to a sweeping capacity accreditation that will better measure generators’ availability based on predetermined risky hours.

MISO said it will push back a contentious filing for a new, marginal approach to capacity accreditation into early next year.

Stakeholders remain frustrated with MISO’s plan to enact a marginal capacity accreditation as staff insist that the approach will measure the true value of capacity.

MISO is holding to its plan to enact a widescale marginal capacity accreditation while swapping risky hours for peak load to calculate its reserve margin requirements.

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.

Less than a year after it got permission to debut a new availability-based accreditation, MISO is proposing to reformulate how it accredits its resources.

MISO leadership last week committed to holding future talks with stakeholders on how to retool its capacity auction to stimulate more supply.

MISO’s capacity auction shortfall has nearly doubled its probability of load shedding in its Midwest region, prompting discussion of must-offer requirements.
