The Organization of MISO States is preparing a letter to MISO leadership to stress resource adequacy work following the last month’s capacity auction.

MISO officials answered questions about the capacity shortfalls and expensive prices in the 2022/23 auction while stakeholders asked for more supply data.

MISO’s 2022/23 capacity auction saw all its Midwest zones clearing at the nearly $240/MW-day cost of new entry, signaling a need for additional generation.

The OMS and the Independent Market Monitor resuscitated a longstanding debate over whether the RTO should adopt a sloped demand curve in its capacity auctions.

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.
