Harrison County · MS
Gulfport is the headquarters city for Mississippi Power, a Southern Company subsidiary that serves the state's Gulf Coast — a genuinely different utility from Entergy Mississippi, which covers Jackson and most of the rest of the state. The Mississippi Gulf Coast experienced some of the most severe, highest storm-surge damage recorded anywhere during Hurricane Katrina in 2005, giving Gulfport a level of direct, catastrophic hurricane exposure that even coastal Louisiana cities this site covers don't all share to the same degree.
