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.

MISO says it may reduce the capacity accreditation of some of its load-modifying resources in an effort to improve resource availability in its footprint.
