2026 Porsche Taycan GTS: home charging cost in Maryland

A 2026 Porsche Taycan GTS draws 39 kWh per 100 miles per the EPA; at Maryland's 21.27¢/kWh residential rate that's $8.29 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. Charging at home is much cheaper than gas here: 48.2% 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 Maryland costs about $1,244/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,159 a year.

Cost of a full charge

Where this ranks

This combination ranks 15,499 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; Maryland alone ranks 39 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.
