Utility rules and programs for Madison

Huntsville Utilities serves homes in Madison.

UtilityTypeGenerator rules
City of Huntsvillecity-ownedAsk your utility for its rules. Alabama Power does not allow generation to run in parallel with its lines without written approval, and a transfer switch keeps backup power from feeding the grid; have a licensed electrician install it and ask your city whether a permit is needed.

Program details are from each utility’s own pages (read October 2026). See the Alabama incentives table for statewide credits and a status for every program.

What to plan for in Madison

  • Lightning (very high): Lightning causes short outages and damages electronics. Surge protection and a battery that switches over automatically protect the things you care about.
  • Tornadoes (relatively high): Tornado-season storms cut power quickly. A battery that switches on by itself, or a portable generator ready to go, covers the first night; sirens and weather radios need power too.
  • Strong winds (relatively high): High winds knock out lines on ordinary days. A battery or portable power station handles the common short outages; add a generator for multi-day repairs.
