The project will fund commercialized zero-emission on-road technologies, facilitate GHG emission reductions, and further the purposes of AB 32, the more recent Senate Bill (SB) 32 (Pavley, Chapter 249, Statutes of 2016), which codified a 2030 GHG emissions reduction target of 40 percent below 1990 levels, SB 1 (Beall, Chapter 5, Statutes of 2017), and related statutes.


The California Air Resources Board (CARB or the Board) is soliciting a Grantee to implement and administer the Hybrid and Zero-Emission Truck and Bus Voucher Incentive Project (HVIP) for Fiscal Year (FY) 2022-23 with an option to renew for a new Grant Agreement for each of the following two years for FY 2023-24 and FY 2024-25. The FY 2022-23 Funding Plan for Clean Transportation Incentives (Funding Plan)1, approved by the Board in November 2022, allocated $265 million for standard HVIP with an additional $325.38 million for set-aside categories.

HVIP accelerates market transformation by incentivizing the purchase of zero-emission heavy-duty trucks and buses for California fleets by providing vouchers for purchasers and lessees for eligible vehicles on a first come, first-served basis. HVIP provides increased incentives for fleets purchasing zero-emission vehicles located in disadvantaged communities with a goal of at least 50 percent of HVIP funding supporting vehicles domiciled in disadvantaged communities. In addition, HVIP incorporates set-asides for school buses, drayage, and transit vehicles.

HVIP stimulates the development, deployment, and commercialization of advanced vehicle technology. These technologies are critical to help California meet its near- and long-term air quality and climate change goals. Additionally, the project benefits the citizens of California by providing immediate air pollution and greenhouse gas emission reductions.

HVIP will continue to be administered and implemented through a partnership between CARB and a Grantee, selected via this competitive solicitation. Eligible applicants wishing to apply for the role of project administrator must submit an application electronically to CARB no later than 5:00 p.m. (PT) August 29, 2023. More information regarding the application process can be found in Section VIII, Application Instructions of this solicitation.
