FERC issued MISO a show-cause order saying it appeared to violate its tariff by failing to publish a system-wide unforced capacity ratio ahead of its auction.

MISO will likely delay its capacity auction by at least a month after FERC issued a show-cause order regarding a capacity ratio the RTO is required to publish.

MISO said a spring under typical demand and generation outages shouldn’t prove much trouble.

MISO can continue as planned with its seasonal capacity auction and availability-based resource accreditation, FERC ruled, rejecting rehearing requests.

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 mostly sailed through fall, encountering rough patches only when unseasonably warm weather clashed with generator maintenance season.

Months before MISO debuts a seasonal capacity auction, its IMM said he has uncovered a faulty assumption behind the seasonal capacity requirements.

ISO-NE is narrowing down its options as it moves forward with revamping its process for resource capacity accreditation.

MISO broadcast to stakeholders that it’s ready for a sloped demand curve in its capacity auction.

Stakeholders are seeking a FERC rehearing of MISO’s seasonal auction design, while the RTO wants it to reconsider its minimum capacity obligation.
