Funding Updates

HVIP re-opened to voucher requests at 10:00 a.m. Pacific on March 30, 2022 with nearly $430 million available across standard HVIP and set-aside funds for public transit buses, class 8 tractors performing drayage operations, and school buses.

HVIP still remains open for all voucher requests. While funds specifically set aside for drayage trucks have been fully subscribed, requests for drayage and all class 8 tractors will continue to be accepted and funded out of standard HVIP funds.   

The table below shows currently available funds, and will continue to be updated daily during business hours. Dealers will also be advised of funding status via the online Voucher Processing Center portal. 

Funding status confirmations will continue to be sent as more voucher requests come in; requests are first-come, first-served except for the Public School Bus Set Aside for Small and Medium Air Districts. If you have voucher-specific questions, please contact [email protected].

Funding Status

This table is updated daily during business hours. Requests in the categories shown in this table are first-come, first-served.

Funding Category  Funding Category Status  Funding Available*
Standard HVIP Open $29 million available for fleets of any size; plus an additional $15 million available for fleets with 10 or fewer vehicles**
Public Transit Bus Set-Aside Open $54 million

Public School Bus Set Aside for Small and Medium Air Districts Open Up to $122 million***

* As of 6/27/2022

** This takes into account the Small Fleet Provision in the FY21-22 Implementation Manual. HVIP will reserve $25 million of standard HVIP funds (exclusive of set-asides) for fleets of 10 or fewer trucks or buses until the third quarter of 2022. If small fleets have not already requested $25 million by Oct. 1, 2022, any remaining funding from the $25 million reserve would be available to fleets of any size. A small fleet is defined as any entity that has 10 or fewer vehicles with a GVWR greater than 8,500 lbs under common ownership and control and domiciled in California, including inoperable or unregistered vehicles. Unredeemed HVIP vouchers count toward this total. For example, a fleet with 8 vehicles with a GVWR greater than 8,500 lbs under common ownership and control and domiciled in California that also has 4 existing unredeemed voucher requests does not qualify as a small fleet in HVIP. Any entity requesting more than 10 HVIP vouchers also does not qualify as a small fleet in HVIP.

*** The Public School Bus Set-Aside for Small and Medium Air Districts has a 90-day application window, the first day of which was March 30, with specific prioritization criteria during that timeline for disadvantaged communities. Updates on this set-aside are at

Example Calculation

An approved vehicle’s voucher amount is determined by multiplying the appropriate base incentive amount with applicable voucher modifiers. There can be multiple modifiers, but the additions or subtractions do not compound. This example is for illustrative purposes only. A local air district grant provides $100,000 to a private fleet to replace an old truck with a new $140,000 diesel truck of 35,000 lbs GVWR. HVIP augments this grant by providing a $150,000 voucher for the purchaser to upgrade to a $300,000 zero-emission truck. The zero-emission truck incremental cost is $160,000. HVIP voucher amount combined with the air district funding cannot exceed 90 percent of the zero-emission vehicle purchase cost (excluding taxes and fees). HVIP funding may not pay for any taxes or fees. Taxes and fees must be paid for by another funding source.

In this case, $150,000 HVIP voucher < $160,000 vehicle incremental cost

$100,000 district grant + $150,000 HVIP voucher = $250,000

$300,000 * 90 percent = $270,000

$250,000 total public funds < 270,000

The transaction can proceed without discounting HVIP voucher.
