Utility rules and programs for Wheaton

Commonwealth Edison serves homes in Wheaton.

UtilityTypeGenerator rules
Commonwealth Edison Coinvestor-ownedWe found no statewide Illinois rule on generator transfer switches; local permits apply (Chicago requires a permit and a Chicago-licensed electrical contractor), and the switch must keep the generator from feeding power back onto utility lines.

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

What to plan for in Wheaton

  • Cold waves (very high): Cold waves raise demand and can cause both outages and frozen pipes. Keep at least one room warm with a battery-run heater circuit or a generator.
  • Tornadoes (very 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 (very 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.
