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.

Vistra said MISO’s “irreparably dysfunctional” capacity auction design deserves blame for its decision to shutter the last of its Midwest coal plants.

MISO and its Independent Market Monitor are at odds over how and how quickly the RTO should address its resource adequacy, board members heard Tuesday.

MISO said a new rule prohibiting resources on extended outages from offering capacity contributed to the historic spike in Zone 7 prices in April’s PRA.

Stakeholders asked if MISO’s new long-term generation outage policy played a role in driving up Michigan capacity prices in the Planning Resource Auction.

MISO’s plan to crop some load-modifying resources’ capacity credits remains unpopular with stakeholders, prompting the RTO to postpone the accreditation.

MISO is contemplating creating a seasonal design for its resource adequacy construct to manage potential reliability risks outside of the summer months.

MISO’s capacity auction marked the RTO’s first clearing price set by its cost of new entry, as prices in the Lower Peninsula rocketed to almost $260/MW-day.

MISO is looking into a forward market mechanism and improvements to its scarcity and emergency pricing under its resource availability and need project.
