2026 Porsche Taycan Turbo S: home charging cost in Oklahoma

A 2026 Porsche Taycan Turbo S draws 42.8 kWh per 100 miles per the EPA; at Oklahoma's 13.37¢/kWh residential rate that's $5.72 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: 64.3% less than gas per mile, here specifically.

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.
