EV Ownership in Tennessee

Tennessee is a fast-growing EV market, driven by Nashville and Knoxville. The state hosts Volkswagen's Chattanooga EV assembly plant and is a major hub for EV battery manufacturing (LG Energy Solutions in Holland). TVA's low electricity rates are a major advantage.

Incentives & Programs

Tennessee has no state EV tax credit. Federal incentives apply. TVA (Tennessee Valley Authority) offers some of the lowest electricity rates in the US and partners with utilities on EV programs. Nissan's Smyrna plant (near Nashville) is transitioning to EV production.

Charging Infrastructure

I-40, I-24, and I-75 corridors are well-covered. Nashville and Knoxville have solid charging networks. Memphis is growing. Appalachian rural stretches are more limited.

Grid & Energy Source

TVA's grid is approximately 40% nuclear (with several plants), ~25% natural gas, and growing solar and wind. The nuclear base makes Tennessee EV charging relatively clean among Southern states.

TennesseeElectricity Rates & EV Savings

The average residential electricity rate in Tennessee is $0.13/kWh, which is below the national average of $0.17/kWh. With a gas price of $3.30/gallon, Tennessee ranks as a favorable state for EV ownership.

Moderate climates provide near-optimal EV performance year-round. Expect battery range close to EPA estimates and consistent charging costs across seasons. Your Audi Q8 e-tron's 106 kWh battery provides up to 285 miles of EPA-rated range. Real-world range may vary by 10–30% depending on temperature, speed, and terrain.
