2026 Kia Niro Electric: home charging cost in Tennessee
At Tennessee's residential electricity rate of 13.9¢/kWh, a 2026 Kia Niro Electric (rated 30 kWh per 100 miles by the EPA) costs $4.17 to drive 100 miles on home charging, against $16.02 for the same distance in a car averaging 25.5 mpg on gasoline at $4.085/gallon. Charging at home costs a fraction of what gas would here: 74% less than gas per mile, here specifically.
What a year of driving costs
Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2026 Kia Niro Electric charged at home in Tennessee costs about $626/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,777 a year.
Filling up the 2026 Kia Niro Electric, in dollars
A 2026 Kia Niro Electric needs roughly 75.9 kWh to reach its EPA-rated 253-mile range, which runs about $10.55 at 13.9¢/kWh in Tennessee.
How this compares nationally
This combination ranks 1,381 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Kia Niro Electric alone ranks 58 of 400 models for efficiency; Tennessee alone ranks 13 of 51 states for electricity price.
Next step: home charger installation
The numbers above assume Level 2 home charging is already in place — the electrical work behind that is a real, separate cost that varies by panel, wiring, and local labor rates, not something this page's per-mile math includes.
Ask a licensed Tennessee electrician to quote the install before this math becomes a real decision.
