The Sierra Club, Natural Resources Defense Council and the Sustainable FERC Project are seeking a rehearing of MISO’s sloped demand curve in its capacity auction.

June brought a 2-GW lower peak than anticipated and unchanged real-time and fuel prices from last year, MISO said in a monthly operations report.

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.
