Tennessee home charging cost for the 2026 Porsche Taycan Turbo S

In Tennessee, home electricity runs 13.9¢/kWh — put a 2026 Porsche Taycan Turbo S's EPA-rated 42.8 kWh/100mi against that and 100 miles costs $5.94, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home is much cheaper than gas here: 62.9% less than gas per mile, here specifically.

Annual cost, at 15 thousands miles a year

At fueleconomy.gov's default of 15,000 annual miles, the 2026 Porsche Taycan Turbo S costs roughly $892 a year to charge at home in Tennessee, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,511 a year.

What one full charge costs

Covering the 2026 Porsche Taycan Turbo S's EPA-rated 266-mile range takes about 113.8 kWh, which costs about $15.81 at Tennessee's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.

Where this ranks

This combination ranks 9,156 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Porsche Taycan Turbo S alone ranks 311 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.
