Vehicle-to-Grid Energy Credit
Retail electricity customers with at least one grid-integrated electric vehicle (EV) may qualify to receive kilowatt-hour credits for energy discharged to the grid from the EV's battery at the same rate that the customer pays to charge the battery. A grid-integrated EV is defined as a battery-powered motor vehicle that has the ability for two-way power flow between the vehicle and the electric grid as well as communications hardware and software that allow for external control of battery charging and discharging. (Reference Delaware Code Title 26, Chapter 10, Section 1001 and 1014g)
Idle Reduction Weight Exemption
Any motor vehicle equipped with qualified idle reduction technology may exceed the state gross, axle, tandem, or bridge weight limits by up to 400 pounds to account for the weight of the technology. The additional weight may not exceed the actual weight of the idle reduction unit. To qualify for the exemption, the vehicle operator must also be able to prove the weight of the idle reduction technology and demonstrate that the technology is fully functional. (Reference Delaware Code Title 21, Chapter 45, Section 4503f)
Alternative Fuel Tax Exemption
Taxes imposed on alternative fuels used in official vehicles for the United States government or any Delaware state government agency, including volunteer fire and rescue companies, are waived. Alternative fuel retailers must obtain a fuel supplier's license from the Delaware Department of Transportation (DelDOT), and operators or owners of vehicles using alternative fuel must obtain either a special fuel user's license from DelDOT or pay the special fuel tax. (Reference Delaware Code Title 30, Chapter 51, Subchapter II)
