Plug-in Electric Vehicle (PEV) Decal Fee

Owners of PEVs must pay an annual decal fee of $200. Multipurpose vehicles and motorcycles are exempt. Multipurpose vehicles are defined as having at least four wheels, an unladen weight of at least 300 pounds (lbs.) but less than 3,000 lbs., a permanent upright seat or saddle for the driver which is mounted at least 24 inches from the ground, and an identifying number (Reference House Bill 0144, 2021, and Wyoming Statutes 31-3-102 (a)(xxiii), 31-1-101(a)(xv)(M), and 39-17-301 (a))

Alternative Fuel Tax Rate

A license tax of $0.24 per gasoline gallon equivalent (GGE) or diesel gallon equivalent (DGE) is collected on all alternative fuel used, sold, or distributed for sale or use in Wyoming. Alternative fuels include compressed natural gas (CNG), liquefied natural gas (LNG), propane, electricity, and renewable diesel. For taxation purposes, one GGE of CNG is equal to 5.66 pounds (lbs.), one DGE of LNG is equal to 6.06 lbs., one GGE of propane is equal to 1.35 gallons, and one GGE of electricity is equal to 33.56 kilowatt-hours. For more information, refer to the Wyoming Department of Transportation Tax Rates website. (Reference Wyoming Statutes 39-17-104, 39-17-204, 39-17-301. 39-17-303, and 39-17-304)

Regional Electric Vehicle (REV) West Plan

Wyoming joined Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, and Utah (Signatory States) in signing the REV West memorandum of understanding (MOU) to create an Intermountain West Electric Vehicle (EV) Corridor that will make it possible to seamlessly drive an EV across the Signatory States' major transportation corridors.

• Educate consumers and fleet owners to raise EV awareness, reduce range anxiety, and increase EV adoption;
• Coordinate on EV charging station locations to achieve a consistent user experience across Signatory States;
• Use and promote the REV West Voluntary Minimum Standards for EV charging stations and explore opportunities for implementing the standards in Signatory States;
• Identify and develop opportunities to incorporate EV charging stations into planning and development processes such as building codes, metering policies, and renewable energy generation projects;
• Encourage EV manufacturers to stock and market a wide variety of EVs within the Signatory States;
• Identify, respond to, and collaborate on funding opportunities to support the development of the plan; and
• Support the build-out of direct current (DC) fast charging stations along EV corridors through investments, partnerships, and other mechanisms.

Diesel Emission Reduction Project Funding
