What District of Columbia Residents Should Know
Electricity in District of Columbia averages $0.158 per kWh — near the national average — while regular gasoline runs $3.50 per gallon, which is above the U.S. mean. At these rates, an average EV costs roughly $0.05 per mile to drive compared to about $0.12 per mile for a 30-mpg gas car. Over 12,000 miles a year, that translates to approximately $840 in annual fuel savings for the EV owner.
District of Columbia utilities offer time-of-use rates with off-peak pricing as low as $0.100 per kWh. Charging overnight during off-peak hours can cut your per-mile EV cost by up to 58% compared to peak rates. If you pair off-peak charging with a Level 2 home charger, you can keep annual fuel costs well under $360 — a fraction of what most gas vehicles cost to fuel.
Fuel is only part of the story. EVs skip oil changes and spark plugs and wear brakes far more slowly thanks to regenerative braking, typically saving another $0.04–$0.06 per mile in maintenance — roughly $500–$700 a year at 12,000 miles. The EV case is strongest for District of Columbia drivers who can charge at home and keep the vehicle for several years; if you rely mostly on public fast charging or drive very little, the advantage narrows.
