MISO execs say long-term transmission and a capacity market redesign are a must in response to rising climate risks and fleet change.

MISO postponed filing tariff revisions to implement 4 seasonal capacity auctions and impose a more rigorous accreditation process on participating resources.

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

MISO staff and stakeholders clashed in front of board members on whether the RTO’s proposed capacity accreditation design should move forward.

MISO reiterated the extraordinary nature of mid-February’s winter storm, promising more data later this month and resource adequacy solutions by year-end.

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

Fall in MISO was a study in record wind production, but it came with a price, as it produced more than half of the quarter’s real-time congestion.

In an effort to avoid an increase in emergency operating conditions, MISO plans to develop a new direction for its capacity auction.

MISO will evaluate the merits of defining new seasonal reliability criteria and implementing a sub-annual capacity construct, stakeholders learned.

Stakeholders are divided on whether MISO has conducted enough analysis to justify adopting seasonal capacity auctions and loss-of-load expectation studies.
