Innovative Small e-Fleet Pilot Program

The Innovative Small e-Fleet Pilot Program (ISEF) is part of the Clean Truck and Bus Voucher Incentive Project, also known as HVIP. ISEF was established to support small fleets and owner-operators who may face barriers to zero-emission vehicle adoption, such as high upfront costs, limited financing & insurance options, and complex planning for fueling infrastructure. ISEF eligible small fleets can receive increased vouchers for innovative mechanisms such as all-inclusive leases, peer-to-peer truck sharing, truck-as-a-service, and individual owner planning assistance, as well as other mechanisms.
