MISO stakeholders have adopted the spirit of MISO’s new code of conduct into their comprehensive rulebook while adding rules that empower committee chairs to shut down rude behavior or order attendees out of conference rooms.

Vistra has agreed to pay $38 million to wind down a long-running FERC inquiry into whether it manipulated prices in MISO’s 2015/16 capacity auction.

A new report shows the MISO footprint could ring up $27 billion in additional system costs through 2050 if it and members miss the boat on developing new gigawatts of battery storage.

Five state public service commissions have banded together to request that FERC order a recasting of MISO’s long-range transmission projects, arguing the projects aren’t as beneficial as MISO has advertised.

The MISO Independent Market Monitor called on the RTO to develop a penalty system for generation for underperformance during emergencies.

Ameren Illinois argued to FERC that it should have dibs on sections of two competitive long-range transmission projects worth almost $2 billion from MISO’s second portfolio, claiming Illinois’ “first in the field” doctrine is tantamount to a right of first refusal law.

MISO expects to exceed its quarterly project maximum when it begins accepting the first generation project proposals under its interconnection queue express lane.

MISO issued a slew of warning notices and operating instructions — especially in the South region — to help deal with oppressive July heat, forced generation outages and strained transmission.
