Quick Answer

Charging a 2026 Tesla Model S at home in Montana costs approximately $39/month — that's $0.039/mile and saves $1,113/year compared to a 28 MPG gas car at Montana's gas price of $3.70/gallon.

Sedans offer excellent aerodynamics and some of the highest efficiency ratings in the EV market, making them among the most cost-effective EVs to run daily. Cold weather reduces EV range by 20–40% as the battery heats itself and the cabin. Use scheduled departure to pre-heat on shore power before driving.

EV Ownership in Montana

Montana has low EV adoption due to its vast rural geography and limited charging infrastructure. Billings, Missoula, and Bozeman are the primary markets. The state's scenic driving routes and outdoor culture are increasingly attracting EV road-trippers.

Incentives & Programs

Montana has no state EV tax credit. Federal incentives apply. NorthWestern Energy offers no dedicated EV rate plans currently, though this may change as the market grows.

Charging Infrastructure

I-90 and I-15 corridors have sparse DCFC coverage. Billings, Missoula, and Bozeman have limited urban charging. Gaps of 100+ miles exist on many Montana routes — this is one of the most challenging EV states for long-distance driving.

Grid & Energy Source

Montana's grid is roughly 60% hydro and 30% coal — an unusual mix. The hydro-heavy portion makes Montana's EV charging fairly clean, though the coal-heavy Billings area is somewhat less so.

MontanaElectricity Rates & EV Savings

The average residential electricity rate in Montana is $0.13/kWh, which is below the national average of $0.17/kWh. With a gas price of $3.70/gallon, Montana ranks as a favorable state for EV ownership.

Cold weather reduces EV range by 20–40% as the battery heats itself and the cabin. Use scheduled departure to pre-heat on shore power before driving. Your Tesla Model S's 95 kWh battery provides up to 405 miles of EPA-rated range. Real-world range may vary by 10–30% depending on temperature, speed, and terrain.

Tips for Charging Your Tesla Model S in Montana

Montana's cold climate and charging infrastructure have specific implications for Tesla Model S owners. Here are practical tips to maximize range and minimize charging costs in this state:

Montana's charging gaps are real — use A Better Routeplanner (ABRP) to map your entire Montana route before departure.

Glacier and Yellowstone access roads have limited charging. Plan to arrive with a near-full charge.

Montana's winters are severe: -20°F is not uncommon. Range can drop 40–50% in extreme cold — treat the battery like a critical resource.

Bozeman is the most EV-friendly city in Montana, with growing Tesla and third-party infrastructure.
