How Much Does It Cost to Charge a Tesla Model S in Idaho?

Quick Answer

Charging a 2026 Tesla Model S at home in Idaho costs approximately $33/month — that's $0.033/mile and saves $1,186/year compared to a 28 MPG gas car at Idaho'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 Idaho

Idaho has a small but growing EV market, centered on Boise and the Treasure Valley. The state's exceptionally low electricity rates ($0.11/kWh) make it one of the cheapest places in the US to charge an EV.

Incentives & Programs

Idaho offers no state EV tax credit, but federal incentives apply. Idaho Power offers time-of-use plans with off-peak rates that can go even lower. The base $0.11/kWh rate is already competitive with TOU off-peak rates in most states.

Charging Infrastructure

I-84 through Boise is well-covered. North-south stretches (US-95 toward Coeur d'Alene) are improving. Southern Idaho's rural stretches require careful planning. Boise has the best urban charger density.

Grid & Energy Source

Idaho's grid is dominated by hydropower (~65%) from dams on the Snake River and Columbia River system. This makes Idaho EV charging among the cleanest in the US, with among the lowest carbon footprints nationally.

IdahoElectricity Rates & EV Savings

The average residential electricity rate in Idaho is $0.11/kWh, which is below the national average of $0.17/kWh. With a gas price of $3.70/gallon, Idaho 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 Idaho

Idaho'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:

At $0.11/kWh, Idaho has some of the cheapest home EV charging in America — even without a TOU plan, costs are low.

Idaho's hydro-heavy grid means you're essentially charging on clean, renewable power year-round.

Winter snowpack and mountain terrain near Sun Valley and Coeur d'Alene reduce range — charge fully before mountain routes.

Idaho Power's overnight TOU rates can drop charging costs further to as low as $0.08/kWh.
