Corpus Christi is ground zero for Gulf Coast hurricane risk in Texas. Hurricane Harvey's direct hit in 2017 as a Category 4 storm was a defining moment for the Coastal Bend. AEP Texas serves the area, and extended outages after tropical systems are routine. The city's location on the Gulf makes it one of the highest-priority generator markets in Texas.
