Alabama has a genuinely distinctive utility and regulatory split running roughly along the Tennessee Valley watershed: Alabama Power, an investor-owned utility regulated by the state Public Service Commission, serves Birmingham, Mobile, and the southern two-thirds of the state, while Huntsville and the rest of northern Alabama sit in Tennessee Valley Authority (TVA) territory, served by municipal distributors like Huntsville Utilities that purchase wholesale power under federal oversight instead. On top of that structural split, Alabama's outage risk varies by region too — Mobile's direct Gulf Coast position carries real hurricane exposure that inland Birmingham and Huntsville don't share.

Regional considerations across Alabama
Alabama Power (investor-owned, state Public Service Commission-regulated) serves Birmingham and Mobile in the southern two-thirds of the state, while Huntsville sits in TVA territory, served by a municipal distributor under federal oversight instead — a genuinely different structure within one state, not just a naming difference.
Mobile's direct Gulf Coast position gives it real hurricane and storm-surge exposure that inland Birmingham and Huntsville simply don't share, even though Birmingham and Mobile share the same utility.
Huntsville and the broader Tennessee Valley region share a spring severe-thunderstorm and tornado pattern with neighboring Chattanooga and Nashville, Tennessee — a genuinely cross-state regional weather corridor, not an Alabama-specific pattern.
