Maryland home charging cost for the 2026 Tesla Model S Plaid

In Maryland, home electricity runs 21.27¢/kWh — put a 2026 Tesla Model S Plaid's EPA-rated 30.6 kWh/100mi against that and 100 miles costs $6.51, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home is much cheaper than gas here: 59.4% 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 Tesla Model S Plaid costs roughly $976 a year to charge at home in Maryland, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,427 a year.

Cost of a full charge

Covering the 2026 Tesla Model S Plaid's EPA-rated 368-mile range takes about 112.6 kWh, which costs about $23.94 at Maryland'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 11,449 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Tesla Model S Plaid alone ranks 70 of 400 models for efficiency; Maryland alone ranks 39 of 51 states for electricity price.

Before you install a home charger in Maryland

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 Maryland electrician to quote the install before this math becomes a real decision.
