MISO still doesn’t have enough justification to institute a minimum capacity obligation, FERC decided last week.

Entergy’s operating companies have mounted a campaign at the D.C. Circuit Court of Appeals to override FERC’s rejection of MISO’s minimum capacity obligation.

Stakeholders are seeking a FERC rehearing of MISO’s seasonal auction design, while the RTO wants it to reconsider its minimum capacity obligation.

MISO can establish a seasonal capacity auction and accreditation but cannot require a minimum capacity obligation, FERC ruled in a pair of orders.

FERC issued two deficiency letters to MISO over the grid operator’s plans to institute a four-season capacity market and a minimum capacity rule.

Stakeholders have extra time to register critiques of MISO’s plan to redefine its capacity market in the 2023-24 planning year.
