10. Challenges Faced by Entergy New Orleans The first priority is the safe restoration of service following the destruction to infrastructure caused by Hurricane Katrina. 1 Massive restoration costs for Entergy New Orleans, Inc. (ENOI) and only partial return of customers could more than double electricity rates. 2 ENOI’s customers, over 20% of which were below poverty-level before Katrina, cannot absorb higher rates of this magnitude. 3 Federal assistance is required soon to protect customers from this severe cost burden. 4 The level of rates required absent Federal assistance will stifle business development and the repopulation of New Orleans, which in turn will cripple the opportunity for economic recovery in this region. 5

Entergy New Orleans’ Restoration Costs Are Highest Relative to Company Size In comparing expected costs across the three most affected jurisdictions, the potential costs at Entergy New Orleans represent a substantial portion of the entity’s net plant, compared to 10% or less at Entergy Louisiana and Entergy Mississippi.
