The list below contains summaries of all Iowa laws and incentives related to electricity.

State Incentives

Alternative Fuel Infrastructure Loans

The Iowa Economic Development Authority (IEDA) Energy Infrastructure Revolving Loan Program (EIRLP) provides individuals, businesses, and utilities with low-interest loans for energy infrastructure projects that facilitate electricity, biofuel, and renewable natural gas transmission, storage, or distribution. For more information, see the IEDA EIRLP website.

(Reference Iowa Administrative Code 261.406)

Alternative Fuel Vehicle (AFV) Grants

The Iowa Economic Development Authority (IEDA) provides grants for projects that benefit Iowa ratepayers and support the implementation of the Iowa Energy Plan, including the purchase of AFVs. Eligible applicants include Iowa businesses, colleges and universities, private and nonprofit organizations. For more information, including eligibility requirements, see the IEDA Iowa Energy Center Grant Program website.

(Reference Iowa Administrative Code 261.404)

Diesel Emission Reduction Project Funding

The Iowa Department of Transportation (IowaDOT) provides funding for the replacement, retrofit, or conversion of medium- and heavy-duty (MHD) on-road diesel vehicles with new diesel or alternative fuel vehicles. Grants are also available for off-road diesel vehicle replacements and repowers. Grants are available for MHD school buses, transit buses, and trucks. Non-road vehicles and equipment may also be eligible for funding. Eligible applicants include government, nonprofit, and private entities that own or operate diesel fleets and equipment. Additional restrictions apply. This grant program is partially funded by Iowa’s portion of the Volkswagen Environmental Mitigation Trust. For more information, including eligible vehicles, see the IowaDOT Diesel Emission Reduction Act Website.

Electric Vehicle (EV) Charging Infrastructure Funding

The Iowa Department of Transportation (IowaDOT) provides funding for publicly accessible Level 2 and direct current fast charging (DCFC) stations. This grant program is funded by Iowa’s portion of the Volkswagen Environmental Mitigation Trust. For more information, including how to apply, see the IowaDOT Volkswagen Clean Air Act Partial Settlements website.

Iowa's National Electric Vehicle Infrastructure (NEVI) Planning

The U.S. Department of Transportation’s (DOT) NEVI Formula Program requires the Iowa Department of Transportation (Iowa DOT) to submit an annual EV Infrastructure Deployment Plan (Plan) to the DOT and U.S. Department of Energy (DOE) Joint Office of Energy and Transportation (Joint Office), describing how the state intends to distribute NEVI funds. The submitted plans must be established according to NEVI guidance.

For more information about Iowa’s NEVI planning process, see the Iowa DOT Electric Vehicle Infrastructure Deployment website. To review Iowa’s NEVI plan, see the Joint Office State Plans for EV Charging website.

(Reference Iowa Code 452A.2, 452A.3, 452A.41, and 452A.86)

Alternative Fuel Vehicle (AFV) Conversion Registration

When a motor vehicle is modified to use a different fuel type or more than one type of fuel, the vehicle’s registered owner must notify the county treasurer of the new fuel type or alternative fuel types within 30 days. If the vehicle is able to use a special fuel, the county treasurer will issue a special fuel identification sticker.

(Reference Iowa Code 321.41)

Alternative Fuel Vehicle (AFV) Demonstration Grant Authorization

The Iowa Department of Natural Resources (Department) may award demonstration grants to individuals who purchase vehicles that operate on alternative fuels, including but not limited to E85, biodiesel, compressed natural gas, electricity, solar energy, or hydrogen. Individuals may use the grants to conduct research connected with the fuel or vehicle. Grant funding to purchase the vehicle is available if the Department retains the title of the vehicle, the vehicle is used for research, and the proceeds from the eventual sale of the vehicle are used for additional research. Grants are subject to funding availability.

(Reference Iowa Code 214A.24)

Alternative Fuel Vehicle Acquisition Requirements

At least 10% of new vehicles purchased by institutions under the control of the state fleet director, including the Iowa Department of Transportation, Board of Directors of Community Colleges, Board of Regents, Commission for the Blind, and Department of Corrections must be capable of operating on alternative fuels. Alternative fuels include E85, B20, natural gas, propane, and electricity. Vehicles and trucks purchased and directly used for law enforcement and off-road maintenance work are exempt from this requirement.

The state fleet must fuel diesel vehicles with biodiesel blends between 2% and 99%, and gasoline vehicles with ethanol blends between 15% and 85%. This requirement does not apply if such blends are not approved by the U.S. Environmental Protection Agency or the vehicle manufacturer. Additional exemptions apply. Vehicles that use the biodiesel and ethanol blends must display a brightly colored, highly visible renewable fuel sticker. Beginning July 1, 2023, and annually thereafter, the Iowa Department of Administrative Services must submit a report detailing the use of ethanol and biodiesel blends in state fleet vehicles to the governor and Iowa General Assembly.

(Reference Iowa Code 89A.360, 8A.362, 8A.368, 216B.3, 260C.19A, 262.25A, 307.21 and 904.312A and House File 2128, 2022)

Electric Vehicle (EV) Charging Station Inspection

The Iowa Department of Agriculture and Land Steward (Department) must inspect EV charging stations owned by licensed electric fuel dealers or users on a biennial basis to ensure electricity is being accurately metered. The Department must use standards published in the National Institute of Standards and Technology Handbook 44 and must notify the Iowa Department of Revenue of noncompliant charging stations.

(Reference House File 666, 2023)

Electric Vehicle (EV) Fee

EV owners must pay an annual fee in addition to standard registration fees. All-electric EV owners must pay an annual fee of $130 and plug-in hybrid electric vehicle owners must pay an annual fee of $65.

(Reference Iowa Code 321.116)

Electric Vehicle (EV) Infrastructure Study

The Iowa Economic Development Authority (IEDA), in collaboration with the Iowa Department of Transportation and Iowa utility industry, conducted a study of EV charging infrastructure to evaluate costs and benefits associated with different options for EV infrastructure support. IEDA submitted the study report to the general assembly in February 2019. For more information, see the IEDA Energy Plans and Reports website.

Electricity Dealer License

A person may not sell or dispense electricity as a vehicle fuel at a location other than a residence or otherwise act as a licensed electricity fuel dealer or user unless the person holds a valid license issued by the Iowa Department of Revenue (Department). To obtain a license, a person must file an application with the Department.

(Reference House File 767, 2019 and Iowa Code 452A.42)

Public Utility Definition

An entity providing electricity for the purpose of electric vehicle charging is not considered a public utility. Regulated public utilities cannot prohibit or restrict the sale of electricity at an electric vehicle charging station.

Electric Vehicle (EV) Infrastructure Support

Iowa 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.
