District of Columbia utilities joined the National Electric Highway Coalition (NEHC), committing to create a network of direct current fast (DC Fast) charging stations connecting major highway systems from the Atlantic Coast to the Pacific of the United States. NEHC utility members agree to ensure efficient and effective fast charging deployment plans that enable long distance EV travel, avoiding duplication among coalition utilities, and complement existing corridor DC fast charging sites. For more information, including a list of participating utilities and states, see the NEHC website.
Laws and Regulations
Medium- and Heavy-Duty Zero Emission Vehicle (ZEV) Deployment Support
California, Colorado, Connecticut, District of Columbia, Hawaii, Maine, Maryland, Massachusetts, New Jersey, New York, North Carolina, Oregon, Pennsylvania, Rhode Island, Vermont, Virginia, and Washington (signatory states) signed a memorandum of understanding (MOU) to support the deployment of medium- and heavy-duty ZEVs through involvement in a Multi-State ZEV Task Force (Task Force).
By January 2021, the Task Force will develop a multi-state action plan to support electrification of medium- and heavy-duty vehicles. The Task Force will consider actions to accomplish the goals of the MOU, including limiting all new medium- and heavy-duty vehicles sales in the signatory states to ZEVs by 2050. The signatory states will also seek to accelerate the deployment of medium- and heavy-duty ZEVs to benefit disadvantaged communities and explore opportunities to coordinate and partner with key stakeholders.
For more information, see the Medium- and Heavy-Duty ZEVs: Action Plan Development Process website.
Zero Emission Vehicle (ZEV) Deployment Support
The Executive Office of the Mayor will establish a transportation electrification program that requires all public buses, light-duty vehicles associated with privately-owned fleets that can transport 50 or more passengers, commercial motor carriers, limousine service vehicles, and taxis certified to operate in the District of Columbia to be ZEVs by 2045.In addition, the District Department of Transportation, in partnership with stakeholders, will develop a plan to encourage and promote the adoption of ZEVs. The plan will include recommendations for strategies to achieve at least 25% ZEV registrations by 2030 and the mayor’s transportation electrification program. For more information, see the Transportation Electrification Roadmap website.(Reference District of Columbia Code 50-741 and 50-921.24)
