Last month, Illinois became the first state in the Midwest, and one of the few states outside the coasts, to establish a state-run incentive program for medium- and heavy-duty (MHD) electric vehicles (EV) that are part of a fleet, such as commercial trucks, transit, and school buses. The primary purpose of the legislation is to support fleet owners and operators who wish to go all electric; although MHD EVs show strong market growth, their adoption has been slow in part due to their high up-front cost. EVs represent less than 1% of new MHDV sales currently and incentives for vehicle purchases are proven to help increase EV adoption. Rebates and tax incentives for light-duty vehicle (LDV) EVs have captured a larger share of the LDV market overall, accounting for roughly 10% of new LDV sales. It’s no surprise that most MHD EVs are sold in states offering a purchase incentive program.
