MISO has expanded its availability-based capacity accreditation proposal for generation resources by including hours that aren’t so risky.

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

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

MISO is still collecting data and reviewing the actions it took during a massive cold spell that gripped most of the U.S. in mid-February.

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.

FERC approved new rules likely to reduce load-modifying resources’ capacity accreditation in MISO, despite several protests from RTO members.

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

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

MISO is offering stakeholders a compromise on one of two proposals it will file with FERC, removing a provision that would eliminate capacity credits for slow-response LMRs.
