Many stakeholders are uneasy with MISO's plan for a seasonal capacity accreditation based on a generating unit’s past performance during tight conditions.

The D.C. Circuit Court of Appeals agreed with Public Citizen that FERC hasn't explained why it continues to uphold the expensive Southern Illinois capacity price produced in MISO’s 2015/16 capacity auction.

MISO's proposed seasonal accreditation for capacity resources remains a point of contention among the RTO, its Market Monitor and the stakeholder community.

In his annual State of the Market report, MISO’s Monitor said transmission congestion and heightened ramping needs continue to dog the RTO.

MISO said it will attempt at a long-term resource forecast, taking into account members' evolving resource mix over a 20-year timeframe.

MISO’s ninth annual capacity auction cleared MISO South zones — two months removed from emergency load shed orders — at just a penny/MW-day.

While it warns of more system risk in the coming years, MISO is preparing for an unremarkable spring and a routine capacity auction.

MISO said it is close to completing a proposal to create a four-season capacity market after floating a rudimentary plan with skeptical stakeholders.

MISO plans to subdivide its annual capacity auction by seasons to better manage reliability risks caused by renewables’ growing share of the resource mix.

MISO's resource adequacy staff is considering multiple options to implement a sub-annual capacity mechanism.
