Entergy has warned that some customers could be without power for weeks as Hurricane Ida strikes MISO South. 

Entergy said Hurricane Ida caused "catastrophic" transmission failures Sunday, leaving more than a million customers -- including all of New Orleans -- in the dark.

While Entergy New Orleans has expedited one transmission reliability project, Entergy Arkansas has canceled four reliability projects approved by MISO in 2018. 

Stakeholders say it's ill-advised for MISO to propose separate cost allocation methods for long-range transmission projects in MISO South versus MISO Midwest.

State commission staff from MISO South questioned MISO's long-range transmission plan at an Entergy State Regional Committee meeting.

MISO’s ninth annual capacity auction cleared MISO South zones — two months removed from emergency load shed orders — at just a penny/MW-day.

MISO unveiled a first look at possible long-range transmission projects, igniting testy exchanges between stakeholders over the necessity of grid expansion.

While it warns of more system risk in the coming years, MISO is preparing for an unremarkable spring and a routine capacity auction.

MISO is still collecting data and reviewing the actions it took during a massive cold spell that gripped most of the U.S. in mid-February.

The inability of Midwestern grid operators to recover quickly from extreme winter weather drew customer anger, along with scrutiny from regulators.
