MISO has multiple planning topics to tackle on the horizon, with work involving an update of merchant HVDC interconnection procedures, making expedited transmission project reviews more manageable, and evaluating co-located load and generation seeking interconnection.

The D.C. Circuit Court of Appeals rejected Entergy’s challenge of MISO’s seasonal capacity accreditation and generator outage rules, two years after FERC approved the rules.

FERC said it needs more explanation behind MISO’s plan to use a capacity accreditation that would accredit resources based on a combination of their projected availability and historical performance during periods of high system risk.

MISO plans to pursue a more straightforward, 50% peak load megawatt cap to limit the number of generator interconnection requests it will accept annually.

Coal plants in the Central U.S. are elbowing out lower-cost, cleaner generation and have collected more than $1 billion in uneconomic payments over a three-year span, the Natural Resources Defense Council said in a new report.

MISO’s $25 billion, mostly 765-kV long-range transmission package for the Midwest region is nearing finalization, while the Independent Market Monitor continues to doubt the necessity of the projects.

A band of Michigan utilities wants the option to decline MISO’s affected system-style studies on distributed energy resources.

A group of utilities have filed for rehearing of a show cause order FERC issued in June that could change the practice of who pays for interconnection lines at four ISO/RTOs.

Clean energy nonprofits continued to try to persuade Entergy and MISO South state commissioners to embrace a broader view of cost allocation for an upcoming long-range transmission portfolio the RTO intends for the subregion.
