About the Tesla Model S in Maryland
The Tesla Model S carries a 100 kWh usable battery and achieves about 3.5 miles per kWh at the wheels under EPA-combined conditions. In Maryland, where residential electricity averages 22.07¢/kWh, that translates to roughly $7.01 per 100 miles — for comparison, a gasoline car at 30 MPG and $3.50/gallon costs $11.67 per 100 miles, so a Tesla Model S owner in Maryland saves about $559/year on fuel relative to that baseline.
This estimate is for home Level 2 charging only. Public DC fast charging typically costs 2-3× the home rate; if you primarily fast-charge, your annual cost will be higher.
