Local Education Agency School Bus Replacement Grants  Funds to be available in FY23-24

As of 11/28/23

Note: Public School Bus and ISEF set-asides have separate policies and Implementation Manuals from the other set-asides. See

*Unless otherwise noted, these funds are from FY22-23 allocations. The Transit Set-Aside includes $36 million of FY21-22 funds that are currently available for voucher requests.

**Out of these funds, 70% of Standard HVIP and the Drayage set-aside were reserved for private fleets with 100 vehicles or fewer and all public fleets, starting January 1, 2023. Since more than $100 million remained in the reserve on July 1, 2023, HVIP released 30% of the remaining funding to private fleets with more than 100 vehicles at that time. Since funding remained in the reserve on November 1, 2023, all remaining HVIP standard funding and drayage set-aside funding is now available to private fleets with more than 100 vehicles. Voucher requests will continue as normal; the Reserve has no impact on the voucher request process, and dealers should continue to request vouchers as normal. The Reserve only applies to the FY 22-23 allocation.

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 are forthcoming

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.

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.

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.

The +100% base adjustment for public and 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.

Also 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 and domiciled in California. 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. POs can be no older than 3/30/22.

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. 

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

Base Adjustment Type Adjustment Amount
Fleet Size Adjustments See Fleet Size Adjustments and Bulk Purchase Requirements 
Plug-in Hybrid -50%
In-Use Converted/Remanufactured -50%

The base adjustments affect the base incentive amount of a voucher. These adjustments occur before any voucher modifier is applied. If applicable, the FY22-23 voucher modifiers are applied to the adjusted base incentive amount.

Modifier Type Modifier Amount
Class 8 Drayage Truck Early Adopter* +25%
Refuse* +25%
Disadvantaged Community** +15%
Class 8 Fuel Cell +100%
Public Transit Agencies*** +15%
School Buses for Public School Districts (not including Set-Aside funds) +65%

*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 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.

FY22-23 & FY23-24 Eligible ePTO Voucher Table

Energy Storage Capacity Base Vehicle Incentive*
3 – 10 kWh $20,000
10 – 15 kWh $30,000
16 – 25 kWh $40,000
> 25 kWh $50,000

*Effective November 18, 2022, ePTO funding amounts may cover up to 65% of the incremental cost of the ePTO vehicle, not to exceed the funding levels listed in this table.

Example Calculations

This section provides example calculations of the maximum allowable HVIP voucher amount, based upon assumptions regarding other potential funding sources.  These examples are for illustrative purposes only.  The actual maximum voucher amount will depend upon each specific circumstance.

EXAMPLE 1: 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.

EXAMPLE 2: Transit agencies receive an 80 percent grant from the FTA for most new vehicle purchases, including new zero-emission vehicle purchases. For example, suppose a public transit agency receives a $640,000 FTA grant towards the purchase of a new $800,000 battery-electric zero-emission transit bus of 45,000 lbs. GVWR.  The transit agency also receives $20,000 in Congestion Mitigation and Air Quality (CMAQ) funding for the bus.  In this example, the transit fleet is also receiving $100,000 from CalSTA’s Transit and Intercity Rail Capital Program (TIRCP).  Since it is a zero-emission public transit bus, the sum of HVIP voucher and all other public incentives may not exceed the full vehicle cost and funding from other state incentive programs may be combined.  Therefore, the maximum allowable HVIP voucher could not exceed $40,000 as HVIP vouchers may be applied after all other funding sources have been accounted for.

$640,000 FTA Grant + $20,000 CMAQ Funding + $100,000 TIRCP Funding

=$760,000 Other Public Incentive Funds

HVIP voucher cannot exceed $40,000

The maximum allowable voucher amount may not exceed $40,000 since the sum of all public incentives cannot exceed the full vehicle cost.  The HVIP voucher will be discounted to $40,000.

EXAMPLE 3: A private fleet with 150 existing trucks would like to purchase one Class 8 battery-electric truck ($120,000) that will be used for drayage operations. The voucher base adjustments will be applied first and will compound with other modifiers; therefore the -20 percent voucher base adjustment gets applied to the $120,000 voucher amount totaling $96,000. Adding the sum of its modifier ($96,000 *25 percent = $24,000), the full incentive amount for the private fleet is $120,000.
