Jacksonville is the largest city by area in the contiguous US, and its sprawling layout means power restoration after storms takes longer than in compact metros. JEA, the municipal utility, serves the area. Jacksonville faces both Atlantic hurricanes and nor'easters, plus significant flood risk along the St. Johns River. The city's large military population (Naval Station Mayport, NAS Jacksonville) drives consistent demand for backup power.
