Utility rules and programs for Billings
NorthWestern Energy and Yellowstone Valley Electric serve Yellowstone County, so which rules apply depends on your address.
| Utility | Type | Battery and related programs |
|---|---|---|
| NorthWestern Energy LLC | investor-owned | Electric rebates through June 30, 2027 (heat pump $450, thermostat $70, clothes washer $80) and a free Home EnergyCheck. NorthWestern says it offers no incentive for residential solar installations, and we found no battery or EV charger rebate. |
| Yellowstone Valley Elec Co-op | member-owned cooperative | A third-party guide lists a solar stock-water rebate; we found no home solar, battery or EV rebate we could confirm. |
Program details are from each utility’s own pages (read October 2026). See the Montana incentives table for statewide credits and a status for every program.
What to plan for in Billings
- 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.
- 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.
