Utility rules and programs for Williston
Montana-Dakota Utilities and Mountrail-Williams Electric serve Williams County, so which rules apply depends on your address.
| Utility | Type | Generator rules |
|---|---|---|
| Montana-Dakota Utilities Co | investor-owned | Wiring a generator into a house is electrical work that needs a North Dakota State Electrical Board licensed electrician (NDCC 43-09-09); ask your local building department about permits and use a transfer switch so power cannot flow back onto utility lines. |
| Mountrail-Williams Elec Coop | member-owned cooperative | Wiring a generator into a house is electrical work that needs a North Dakota State Electrical Board licensed electrician (NDCC 43-09-09); ask your local building department about permits and use a transfer switch so power cannot flow back onto utility lines. |
Program details are from each utility’s own pages (read October 2026). See the North Dakota incentives table for statewide credits and a status for every program.
What to plan for in Williston
- 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 (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.
- Ice storms (relatively high): Ice storms bring down lines for days. A standby generator with a transfer switch, or a battery sized for the fridge, furnace blower and well pump, matters more than a small power station.
