Madison County · AL
Huntsville sits in Alabama's TVA territory — the Tennessee Valley Authority footprint that covers northern Alabama, distinct from the Alabama Power territory covering Birmingham and Mobile in the southern two-thirds of the state. Huntsville Utilities, the local municipal distributor, purchases wholesale power from TVA and operates under federal oversight rather than the state Public Service Commission that regulates Alabama Power — a genuinely different regulatory and ownership structure within the same state.
