Utility rules and programs for Des Plaines
Commonwealth Edison serves homes in Des Plaines.
| Utility | Type | Generator rules |
|---|---|---|
| Commonwealth Edison Co | investor-owned | We 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 Des Plaines
- Winter weather (very high): Winter storms and cold snaps combine outages with heating demand. Plan for the furnace blower or heat pump, not just lights, and keep a fuel supply you can reach in snow.
- 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.
