Mississippi home charging cost for the 2026 Porsche Taycan 4 Performance Battery

At Mississippi's residential electricity rate of 15.35¢/kWh, a 2026 Porsche Taycan 4 Performance Battery (rated 38.6 kWh per 100 miles by the EPA) costs $5.92 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 is much cheaper than gas here: 63% less than gas per mile, here specifically.

What a year of driving costs

At fueleconomy.gov's default of 15,000 annual miles, the 2026 Porsche Taycan 4 Performance Battery costs roughly $888 a year to charge at home in Mississippi, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,515 a year.

What one full charge costs

Covering the 2026 Porsche Taycan 4 Performance Battery's EPA-rated 251-mile range takes about 96.8 kWh, which costs about $14.86 at Mississippi'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 9,055 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Porsche Taycan 4 Performance Battery alone ranks 229 of 400 models for efficiency; Mississippi alone ranks 22 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 Mississippi electrician to quote the install before this math becomes a real decision.
