Outcomes and Conclusions

Electric Vehicle Resources in Indiana

  • Indiana has more than 550 public charging stations. View station locations, hours, and charging equipment.
  • Plug-in Electric Vehicle (PEV) Charging Rates:
    • Indiana Michigan Power offers a time-of-use rate to residential customers for plug-in electric vehicles. Time-of-use rate off-peak hours are between 9:00 p.m. and 7:00 a.m. Monday through Friday and all-day Saturday and Sunday. Indiana Michigan Power may require customers to install a metering system that is capable of separately tracking plug-in electric vehicles charging. For more information, see the Indiana Michigan Power Rates and Tariffs website.
    • Indianapolis Power & Light offers special plug-in electric vehicle charging rates, including year-round time-of-use based options, for residential and business customers who own a licensed plug-in electric vehicle. For more information, see the IPL Electric Vehicle Charging website.
  • As of fall 2020, battery electric vehicle owners in Indiana are required to pay an additional registration fee of $150, and plug-in hybrid and hybrid electric vehicles are required to pay an additional registration fee of $50. The Indiana Bureau of Motor Vehicles determines new fee amounts every five years.

Supported by grants and institutional investment, the Center is now the proud owner of three electric vehicles – two plug-in hybrid electric vehicles and one battery electric vehicle – and a charging station that operates 24 hours a day. So far, the battery electric vehicle has performed better operationally and culturally due to monetary savings and reduced environmental impact from gas consumption.

In addition to providing the staff with access to charging infrastructure and electric transportation, the investments added value by increasing the number and diversifying the types of visitors. As part of the Indiana Promise Program, classrooms visit the Center to observe and learn more about electric vehicles and the charging infrastructure, prompting the Center to expand its educational programming.


The Center has not been able to evaluate the savings from one of the hybrid plug-in electric vehicles due to its inability to display total electric miles driven vs. gas miles driven.

The Center noted that having an institutional champion was critical when faced with complaints about pitfalls. To ensure individuals understood the benefits of electric vehicles, the champion did not skip past basic questions from any staff or visitors who were less familiar with this new transportation option.  Additionally, the Center tracked every trip for the first six months to educate and reduce anxiety about the ranges of the electric vehicles.

Director of Ecological Relationships Adam Thada said, “It was important to establish a human resources policy on the charging station from the outset to normalize and encourage the use of electric vehicles. At the Center, this manifested as a modest flat yearly fee for employees who want to charge on a regular basis to combat any perception that anyone was attempting to free ride off the institutional utilities.”
