Summary HVIP Policy and Request Changes, July 2019 – Present

HVIP has made the following updates to the voucher request process:

  • As of July 23, 2019, all funds available for HVIP FY 18-19 have been requested and a waitlist was in effect.
  • On October 24, 2019, the California Air Resources Board approved several changes to HVIP policy. The changes went into effect for all voucher requested after October 24, 2019. The changes were not retroactive and therefore did not affect vouchers added to the waitlist before October 24, 2019.
  • As of November 1, 2019, the California Air Resources Board has closed the waitlist. HVIP is no longer accepting voucher requests as HVIP has received voucher requests for the entire $142 million FY 19—20 budget.
  • On March 18, 2020, voucher requests on the waitlist began to be reviewed for approval. Requests are reviewed in the order they were received by the Voucher Processing Center (VPC). FY 19-20 voucher funding will be sufficient to cover all requests currently on the waitlist.
  •  HVIP anticipates accepting new voucher requests beginning in November 2020, when FY 20-21 funding becomes available.

HVIP Policy Changes

At the October 24, 2019 Board meeting, the California Air Resources Board (CARB) approved several changes to HVIP policy. These changes have been made in order to address a significant funding shortfall, and to align eligible technologies with HVIP goals. California maintains a portfolio of funding programs to support a wider variety of technology options and funding needs. The changes are in effect for all vouchers requested after 12:01 a.m. on Friday, October 25, 2019; the changes are not retroactive and therefore do not affect vouchers added to the Waitlist on or before Thursday, October 24, 2019.

Funding Finder Tool

CALSTART developed the Advanced Vehicle Technology and Infrastructure Funding Finder Tool (Funding Finder Tool) to help fleets identify funding programs for medium- and heavy-duty alternative fuel vehicles, equipment and infrastructure in the state of California. This tool will help interested users navigate funding programs most relevant to specific needs. Users can filter the programs through a variety of options such as location, technology type, vehicle / equipment type, and funding availability. CALSTART is working closely with all state, air district and utility partners to routinely update program funding information.

Please visit and use the tool by following this link:  Funding Finder Tool

As a bonus, the Funding Finder has a page for planning grants related to medium- or heavy-duty and alternative fuel vehicles and infrastructure.

View a virtual walk-through of the Funding Finder on YouTube!

Total Cost of Ownership Estimator

Assessing the total cost of ownership (TCO) is essential when deciding to procure any commercial vehicle, especially when you are interested in zero- and near-zero emission vehicles. We built the California HVIP Total Cost of Ownership Estimator to help you assess the TCO for HVIP-eligible vehicles compared to conventionally-fueled vehicles of the same type and size.

Please visit and use the tool by following this link:  Total Cost of Ownership Estimator

This tool will ask you to enter a few details about the vehicle(s) you are interested in, some details about your fleet, and some financial information. With that information, the tool will then provide you with an estimated payback period for the upfront cost of the zero- and near-zero emission vehicle which is above and beyond the upfront cost of a comparable, conventionally-fueled vehicle. It will also provide you with a breakdown of itemized costs over the service life of both vehicles.

For questions regarding the tool, please contact us at tco@calstart.org.

Frequently Asked Questions

Program Basics

  1. What is the Hybrid and Zero-Emission Truck and Bus Voucher Incentive Project (HVIP) and Low NOx Engine Incentives? HVIP was created to reduce price barriers, enabling fleets to adopt more clean heavy-duty commercial vehicles. Created by the California Air Resources Board (CARB) in 2009, HVIP provides point-of-sale discount vouchers that reduce the purchase cost of vehicles operated in the State of California. HVIP vouchers make zero-emission and Low NOx buses and trucks as affordable as their traditional fossil-fueled counterparts at point of sale and reduce prices for medium- and heavy-duty hybrid vehicles. Funded vehicles include parcel, beverage, and food-distribution trucks, transit buses, shuttle buses, and more.
  2. Why did CARB create HVIP? The goal of HVIP is to accelerate and facilitate the adoption of low-emitting hybrid, low NOx, and zero-emission trucks and buses. These vehicles are relatively new technologies and are therefore more expensive than traditional vehicles, especially in the early market years when production volumes are low. CARB recognizes that these vehicles have the proven ability to reduce criteria and greenhouse gas (GHG) pollutants in California and aims to accelerate the penetration of these cleaner vehicles to help meet state clean air regulations and climate change goals. HVIP is part of the California Climate Investments, a statewide initiative that invests Cap and Trade dollars.
  3. What is unique about HVIP? Vouchers are awarded on a first-come, first-served basis. This means that there is no uncertainty regarding securing funding, and no lengthy application or bid process. HVIP is a streamlined funding mechanism that is set up for ease of use by end-users. Dealers, not purchasers, are responsible for securing HVIP funding – fleet owners do not need to gain an understanding of the voucher process to receive the full benefits of HVIP funding. A list of participating dealers is available here.  HVIP has deployed over 4,400 ultra-clean vehicles since 2009. The program’s success as a powerful tool for rapid deployment has encouraged regional adaptions of the voucher model in other states and on a localized basis, such as within California’s Air Districts.
  4. How can I be notified of HVIP news and events? Sign up for the California HVIP e-mail list by filling out the form: Contact Us.
  5. Who can I contact for more information? Please email info@californiahvip.org or call the HVIP toll-free hotline at 888-457-HVIP.
  6. How do we know how much money is available? The ticker at the top of the home page lists how much money remains available to be requested. This reflects the real-time funds, based on the vouchers requested to-date.
  7. How do I know if a vehicle is eligible for HVIP? All HVIP-eligible vehicles can be found in the clean vehicle catalog. If you think a vehicle is eligible, but do not see it listed, please send an email to info@californiahvip.org.
  8. How much are the vouchers worth? Base voucher amounts vary based on vehicle type, powertrain type, and size. For FY18-19, the base voucher amount ranges from $6,000 for a Class 2 Hybrid Truck or a Bus Conversion to $300,000 for a 40 foot or greater Hydrogen Fuel Cell Electric Bus. Please see the FY18-19 Voucher Funding Tables for further information.
  9. Can HVIP voucher funding be combined with other funding (grants, incentives, etc.)? Yes, however the ability to combine funding sources may be considered on a case-by-case basis. Please contact info@californiahvip.org for more information.
  10. Are light-duty vehicles eligible for HVIP? No, they are not. The Clean Vehicle Rebate Project provides incentives for the purchase or lease of new, eligible zero-emission vehicles, including electric, plug-in hybrid electric, and fuel cell vehicles.
  11. What is a Disadvantaged Community (DAC)? How can I determine eligibility for a DAC “Plus Up”? A DAC is an area within California that is especially vulnerable to the impacts of climate change because of socioeconomic and geographic factors. HVIP provides increased incentives for fleets domiciled within disadvantaged communities. The value of this “plus up” varies by vehicle type and increases for larger vehicles. To determine if a vehicle qualifies for a DAC “Plus Up” (increased funding), enter the domicile address in the address search bar on this website.


  1. I would like to purchase an HVIP-eligible vehicle; how do I apply for a voucher? Fleets do not apply for HVIP vouchers. HVIP-eligible dealers are responsible for securing HVIP voucher funding through the online Voucher Processing Center. A purchaser should connect with an HVIP-approved dealer to acquire their vehicle and the dealer will take it from there to acquire the voucher. If you have a trusted dealer relationship or already have a vehicle in mind, connect us with your dealer and we can help them become HVIP-eligible.
  2. Does the size of the fleet matter? No, fleet size does not matter. Requirements and eligibility do not differ based on the size of the fleet.
  3. Can I apply for more than one voucher? Yes. As of October 25, 2019, fleets may request up to 200 vouchers per calendar year.


  1. I represent a dealership. How do I apply for a voucher? Dealers must be HVIP-certified to be able to submit voucher requests on behalf of their customers. Any dealer or manufacturer who sells HVIP-eligible technologies should reach out to  info@californiahvip.org to begin the certification process. Further instructions can be found here.
  2. I was HVIP-certified in a past year; am I still an eligible dealer? A VPC account may be deactivated if a dealer has not logged in for over 365 days. If you believe your VPC login has been deactivated, please reach out to info@californiahvip.org. The program administrators will likely require that you pass the HVIP Dealer Quiz before your eligibility status is updated. If you have questions, please call the HVIP toll-free line at 888-457-HVIP.
  3. I’m having trouble accessing the Voucher Processing Center, what should I do? You should reach out to info@californiahvip.org. A VPC account may be deactivated if a dealer has not logged in for over 365 days. We can help you restore access.
  4. What paperwork is needed throughout the voucher request and redemption processes? To submit a voucher request, an eligible dealer needs only a Purchase Order that makes clear that HVIP funding would be applied. The documents needed for redemption of an HVIP vehicle voucher can be found here.
  5. My co-worker is HVIP eligible, can I use his or her Voucher Processing Center login? No, you cannot. There should be no sharing of VPC logins within a dealership. Multiple individuals at dealerships can become HVIP-certified: this would allow for multiple individuals to sign off on paperwork for the same voucher and would allow for each dealer to submit and track voucher requests on the VPC.
  6. What happens if a vehicle is delivered/titled/paid for ahead of a voucher request being submitted? It is against HVIP policy to provide funding for vehicles that are delivered/paid for ahead of voucher request. If a vehicle is paid for/delivered ahead of voucher request, the vehicle dealer and purchaser can appeal to CARB to allow for an exception. Please contact info@californiahvip.org for more information.
  7.  Can a dealer purchase a demo vehicle using an HVIP voucher? Yes, if a manufacturer or dealer wants to use an HVIP voucher to buy one of their own vehicles for their own use, they can do so for up to two vehicles every 12 months. A written request and written approval is required. Please contact info@californiahvip.org for more information.  


  1. How does a vehicle become HVIP-eligible?  Vehicle eligibility is handled by the California Air Resources Board. Learn more by clicking on the OEMS tab under How To Participate.
  2. Is funding available for retrofitting? Yes, conversions of trucks and buses from internal combustion to hybrid and zero-emission can be funded through HVIP. Please refer to the FY18-19 Voucher Funding Tables. 
  3. Can a manufacturer purchase a demo vehicle using an HVIP voucher? Yes, if a manufacturer or dealer wants to use an HVIP voucher to buy one of their own vehicles for their own use, they can do so for up to two vehicles every 12 months. A written request and written approval is required. Please contact info@californiahvip.org for more information.
