for Small Fleets

Programs that can now be stacked with HVIP for small fleets include Carl Moyer Memorial Air Quality Standards Attainment Program and the CARB Truck Loan Assistance Program. See more details on page 34 in the FY22-23 Implementation Manual. Per the IM, transit buses operated by or on behalf of a city or county government; a transportation district / transit district; or a public agency, including paratransit and microtransit services may stack State-funded incentives with HVIP regardless of fleet size. When stacking HVIP vouchers with other funding sources for public transit buses, HVIP funding may be combined with the provision that HVIP will only fund the remaining cost up to the maximum voucher amount after the other incentives have been applied at their maximum allowable amounts.

See the next section (Fleet Size Adjustment & Bulk Purchase Requirements) for details of HVIP’s fleet size definition.

Fleet Size Adjustments
and Bulk Purchase Requirements

Voucher amounts are modified according to the information below:

Voucher Adjustment Type and Adjustment to Base Amount* 
Private fleets with 101 – 500 MHD vehicles: -20%
Private fleets with more than 500 MHD vehicles: -50%
Doubled voucher amounts for small fleets effective 11/17/23: More details below

NOTE: Voucher base adjustments will be applied first and will compound with other modifiers. For example, a purchase of a Class 8 battery-electric truck ($120,000) by a private fleet with 150 vehicles (-20 percent) that will be used for drayage operations (+25 percent) would receive the adjusted base voucher amount ($96,000) plus the sum of its modifier ($96,000 *25 percent = $24,000), or $120,000.

*California Native American Tribal Governments and 501(c)(3) nonprofits are exempt from the reductions above. Additionally, purchases of fuel cell vehicles are not subject to the reductions.

Small Fleet Adjustment: The +100% base adjustment for public and nonprofit fleets with 20 or fewer MHD vehicles and for private fleets with 20 or fewer MHD vehicles & less than $15 million annual revenue is available in Standard HVIP, the Drayage Truck Set-Aside, and the Public Transit Set-Aside for any HVIP-eligible vehicles. This includes requests that would have otherwise been ISEF standard purchases. All standard purchases formerly made through ISEF will now be funded through HVIP and all existing ISEF standard purchase vouchers will be automatically adjusted to reflect the new HVIP small fleet incentive levels.

Bulk Purchase Requirement: Starting Jan. 1, 2023, a Bulk Purchase requirement is in effect for private fleets with 501 or more vehicles with a GVWR greater than 8,500 lbs under common ownership and control, based on the fleet size definition explained in our FAQs. Also, such fleets can only request vouchers for vehicles domiciled in a Disadvantaged Community (DAC).

Specifically, the PO must be for at least 30 HVIP eligible vehicles, and the HVIP incentive will be applied only for vehicles purchased above 30. The non-HVIP-funded vehicles in the bulk order do not need to be domiciled in a DAC. The existing fleet voucher request limit of 30 vouchers per fleet per year (50 vouchers for drayage trucks and, starting in 2024, for public transit and refuse) continues to apply, regardless of the size of the bulk order.

Bulk purchases are not required for fuel cell vehicles; they can be purchased in any quantity. Also, 501(c)(3) nonprofits are exempt from the bulk purchase requirement.

Purchase Order Age: Starting 1/1/24, POs or other binding sales agreements can be no older than 90 days before the date of the request, for private entities. For public entities, no older than 3/30/2023.

Fleet Size Definition: See our FAQs on how fleet size is defined.

*As part of CARB’s Refuse Reimagined initiative, a voucher enhancement of 25% is applied to HVIP eligible refuse vehicles used for solid waste collection starting November 18, 2022. This increased incentive amount is available until Dec. 31, 2024. The existing Drayage Truck Early Adopter 25% voucher enhancement is also extended until Dec. 31, 2024.

**For vehicles domiciled in a disadvantaged community that are purchased or leased by any public or private small fleet with 20 or fewer trucks or buses, and less than $15 million in annual revenue for private fleets, or for any purchase or lease by a California Native American tribal government. There is no revenue provision for public or nonprofit fleets.

***The Public Transit Modifier is reserved for transit buses purchased by a city or county government; a transportation district/transit district; or a public agency. Public transit includes paratransit and microtransit services.

Voucher Calculator

The HVIP Voucher Calculator was created with the intent to estimate a voucher amount in HVIP. Users are encouraged to test out the HVIP Voucher Calculator to get a better understanding of how modifiers and base adjustments can affect a voucher amount. Currently voucher amounts can be estimated for Standard HVIP, Innovative Small E-Fleet Set-Aside (ISEF), Public School Bus Set-Aside and the Ports of Los Angeles and Long Beach funding. Funding amount for Zero-Emission School Bus and Infrastructure (ZESBI) incentive project are not available on this calculator. Please visit the ZESBI page for more information. This calculator does not take into account if a funding category has funding available. Please check out our Available Funding section above for accurate funding availability.

This calculator follows the FY23-24 Implementation Manual policy rules and will only be applicable to voucher requests submitted on or after 11/17/2023. The ISEF calculations are based on policy changes from the FY23-24 ISEF Appendix F effective 6/3/24. This calculator does not guarantee a voucher amount or eligibility for voucher modifiers and base adjustments. Currently all voucher modifiers can be stacked together, however there are possibilities where modifiers cannot be stacked due to eligibility requirements. Please use this tool at your discretion.

Voucher amounts are confirmed in the Voucher Processing Center once eligibility information has been submitted and the voucher request has been approved. If you have questions about voucher amounts, base adjustments, or voucher modifier eligibility or requirements, please see the Implementation Manual.
