Utility rules and programs for Idaho Falls
Idaho Falls Power and Rocky Mountain Power serve Bonneville County, so which rules apply depends on your address.
| Utility | Type | Generator rules |
|---|---|---|
| City of Idaho Falls | city-owned | We found no statewide rule specific to generator transfer switches; a licensed electrician should install one under a city or county electrical permit, and the utility may need to know about backup power that could feed the grid. |
| PacifiCorp | investor-owned | We found no statewide rule specific to generator transfer switches; a licensed electrician should install one under a city or county electrical permit, and the utility may need to know about backup power that could feed the grid. |
Program details are from each utility’s own pages (read October 2026). See the Idaho incentives table for statewide credits and a status for every program.
What to plan for in Idaho Falls
- Avalanches (relatively high): Decide what must stay on and size backup to that.
- Cold waves (relatively 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.
- Lightning (relatively high): Lightning causes short outages and damages electronics. Surge protection and a battery that switches over automatically protect the things you care about.
