State Incentives

Wyoming's National Electric Vehicle Infrastructure (NEVI) Planning

The U.S. Department of Transportation’s (DOT) NEVI Formula Program requires the Wyoming Department of Transportation (WYDOT) to submit an EV Infrastructure Deployment Plan (Plan) to the DOT and U.S. Department of Energy (DOE) Joint Office by August 1, 2022, describing how the state intends to distribute NEVI funds. Plans must be established according to NEVI guidance.

For more information about Wyoming’s NEVI planning process, see the WYDOT NEVI Program website.

Alternative Fuel Export Tax Exemption

Alternative fuel sold for use in motor vehicles and intended for export from the state by a licensed alternative fuel exporter is exempt from the alternative fuel license tax. Any person exporting alternative fuel for which the license tax has been paid is eligible for a refund of the license tax paid. The exporter must submit the refund request within one year of the date of fuel purchase. (Reference Wyoming Statutes 39-17-301, 39-17-305, and 39-17-309(c))

Natural Gas Infrastructure Loans

The Wyoming Business Council (Council) can issue loans to businesses for the cost of the engineering, design, real property, equipment, and labor necessary to install a natural gas fueling station. The loan may cover 75% of the total project cost, up to $1 million. Businesses receiving a loan do not have to pay interest or principal payments for the first two years of the loan term. When considering loan applications, the Council will consider existing fueling infrastructure and the volume of private and government fleet vehicles in the geographic area. For more information on loan requirements and applications, see the Council's Loan Programs website. (Reference Wyoming Statutes 9-12-301 through 9-12-304)

Compressed Natural Gas (CNG) Loans

The Wyoming Business Council (Council) administers the Wyoming Partnership Challenge Loan Program to provide low interest matching loans to economic development organizations. The loan may not exceed 75% of the total project cost, up to $1,000,000. The Council may match up to 50% of the total project cost. For more information, including a loan application, see the Council’s Partnership Challenge Loan Program website. (Reference Wyoming Statutes 9-12-301 through 9-12-304)

Utility/Private Incentives

Electric Vehicle (EV) Infrastructure Support

Wyoming utilities joined the National Electric Highway Coalition (NEHC), committing to create a network of direct current fast charging (DCFC) 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 DCFC sites. For more information, including a list of participating utilities and states, see the NEHC website.

Laws and Regulations

Electric Vehicle (EV) Decal Fee

Owners of EVs 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 Wyoming Statutes 31-3-102 (a)(xxiii), 31-1-101(a)(xv)(M), and 39-17-301 (a))

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.

In 2019, the Signatory States signed a revised REV West MOU to update their EV corridor goals based on progress to date. Signatory States are committed to:
  • 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.
The Signatory States maintain a coordination group composed of senior leadership from each state who meet on a quarterly basis and report on the above actions. For more information, see the REV West website.

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)

Alternative Fuel License Fee

Each alternative fuel supplier, refiner, distributor, terminal operator, importer or exporter of alternative fuel used in motor vehicles must obtain an annual license from the Wyoming Department of Transportation to conduct business in the state. The fee for each type of license is $25. (Reference Wyoming Statute 39-17-306)

Alternative Fuel Definition

Alternative fuels are defined as pure methanol, ethanol and other blends of at least 85% alcohol, natural gas, propane, coal-derived liquid fuels, hydrogen, electricity, pure biodiesel, renewable diesel, fuels other than alcohol that are derived from biological materials, and P-series fuels. Biodiesel is defined as mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats that meets current ASTM biodiesel standards. (Reference Wyoming Statutes 39-17-301)

Public Utility Definition

An entity that owns, operates, leases, or controls electric vehicle charging stations is not defined as a public utility. (Reference Senate Bill 0035, 2022)

Compressed Natural Gas (CNG) Deregulation

A non-utility business that sells CNG for use as a motor vehicle fuel is not regulated as a public utility. (Reference Wyoming Statutes 37-1-101)

Idle Reduction Requirement

A driver may not idle a vehicle on a roadway outside a business or residential district when it is practical to stop and park the vehicle. A driver may not leave a vehicle unattended without first stopping the engine and removing the key from the ignition. (Reference Wyoming Statutes 31-5-505 and 31-5-509)
