2026 Porsche Taycan GTS: home charging cost in Maine

In Maine, home electricity runs 29.67¢/kWh — put a 2026 Porsche Taycan GTS's EPA-rated 39 kWh/100mi against that and 100 miles costs $11.56, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home is cheaper than gas here: 27.8% 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 Porsche Taycan GTS charged at home in Maine costs about $1,735/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $668 a year.

What one full charge costs

How this compares nationally

This combination ranks 18,736 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Porsche Taycan GTS alone ranks 237 of 400 models for efficiency; Maine alone ranks 48 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.
