2026 Tesla Model S Plaid: home charging cost in Pennsylvania

A 2026 Tesla Model S Plaid draws 30.6 kWh per 100 miles per the EPA; at Pennsylvania's 20.9¢/kWh residential rate that's $6.39 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: 60.1% less than gas per mile, here specifically.

What a year of driving costs

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.
