Entergy restored power to a fraction of customers in New Orleans Wednesday morning, using a transmission line from the northern side of Lake Pontchartrain.

Entergy embarked on restoration efforts  following Hurricane Ida but won't guess as to how long power could be out for several thousand customers in Louisiana.

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

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