The program was created by the Governor's budget bill, 2005 Wisconsin Act 25. Under the program, DOA provides grants to freight motor carriers (common, contract and private motor carriers) headquartered in Wisconsin to purchase and install idling reduction units for newer truck tractors. Idling reduction units provide an alternative source of power used to heat, cool, or provide electricity to the cab or other parts of a truck in lieu of operating the truck's main drive engine to power these services. The use of idling reduction units on heavy-duty diesel trucks saves fuel and lowers air pollution emissions. Awards are chosen randomly using a computer generated lottery system.

Eligible applicants will receive a reimbursement of up to 50% for the costs of idling reduction equipment and installation. Before applying in the future, applicants should review the rule and changes.

Questions to consider before applying for grant coverage:

  1. Do you own and operate your diesel truck tractor? The person applying for a grant must own and operate the truck.  

  2. Do you lease your truck tractor? Lease vehicles will NOT be eligible to apply due to state statutory language which requires motor carriers to own (possess truck title) and operate their trucks to be eligible.  

  3. Is your diesel truck(s) engine 1999 or newer? The engine model year must be 1999 or newer to be eligible for grant coverage.  

  4. Is your fleet headquartered in the State of Wisconsin? The motor carrier applying for grant coverage must be headquartered in the State of Wisconsin.  

  5. If you are an owner/operator, is your residence in Wisconsin? The owner operator applying for grant coverage must reside in Wisconsin.  

  6. Have you reviewed the Statute, Rule, Factsheet and FAQs to make sure you are eligible to apply for funding?
