EV registration fees in Delaware

Most states charge electric vehicles an extra registration fee to make up for the gasoline tax they do not pay. What Delaware currently has on the books, per the U.S. Department of Energy's Alternative Fuels Data Center:

Electricity price is the state-wide average residential rate from the U.S. Energy Information Administration, Electric Power Monthly table 5.6.A (May 2026). Your own utility's rate — and any time-of-use plan you are on — can differ substantially. Energy use per 100 miles is derived from EPA ratings; see any car's page for the method.
