Zero-Emission School Bus and Infrastructure (ZESBI)

The ZESBI Application Part A opened on Tuesday, May 14th 2024, at 10:00am Pacific Time and will remain open until Monday, September 30, 2024, at 5:00pm Pacific Time.

*Charter schools classified as a non-classroom-based charter school as of FY 2021-22 are not eligible entities. 

Private Schools are not an eligible entity. 

Public school districts in California that own their own school buses are eligible to participate.  This includes public school districts that own their school buses but contract with a County Office of Education or private contractor for maintenance and operations.  Where two or more public school districts have formed a Joint Powers Authority (JPA), and the JPA holds ownership of the school buses, the JPA is eligible to participate. JPAs may use their highest priority criteria school district to serve as the basis for eligibility. Public charter schools that own their own school buses and County Offices of Education that own their own school buses are also eligible to participate. 

Incentive amounts, as shown in the table below, intend to cover nearly, if not all, the full cost of a new zero-emission school bus.

Applicants will be prioritized according to the following:  

Tier 1 – Applicants defined as a small school district, or rural school district, or applicants serving a high percentage of unduplicated pupils (The LEA’s count of unduplicated pupils is 80% or greater of the total district enrollment as reported in CALPADS 2022-23 Fall Submission 1).

Tier 2 – Applicants that serve Disadvantaged Communities and/or Low-Income Communities 

Tier 3 – All remaining eligible applicants located in the State of California  

Applicants within each tier will be ranked based on the timestamp of submission of their complete Application Part A. Applications will be awarded on a first come, first served basis. The timestamp on any application that is missing materials or otherwise deemed incomplete will not be recorded until all application materials are submitted. 

ZESBI requires that the eligible Local Educational Agency (LEA) complete the initial application (Application Part A). 

Eligible applicants interested in applying should be prepared to submit the following:    

1. Letter of Intent signed by an authorized representative stating the applicant’s intent to purchase zero-emission school bus(es). A template can be found here: Letter of Intent.  
2. A current copy of the DMV registration for each old school bus included in Application Part A 
3. A current copy of the California Highway Patrol Safety Certification (CHP 292 or equivalent) for each old school bus included in Application Part A 

The old school bus can be any internal combustion engine using any fuel type. The following are the old school bus eligibility requirements:   

• The school bus chassis must be a 2010 model year or older. The school bus chassis age is verified by the model year listed on the DMV Registration Form.   
• The school bus must be applicant owned. The school bus cannot have a lienholder listed on the DMV Registration Form.   
• The school bus must have a Gross Vehicle Weight Rating (GVWR) greater than 10,000 pounds. School bus(es) with a GVWR of exactly 10,000 pounds or less than 10,000 pounds are not eligible.   
• The school bus must have a current California Highway Patrol Safety Certification (CHP 292 or equivalent) at the time of Application Part A submission. A non-certified school bus will not be able to continue within the application process.  
• Diesel-fueled school bus(es), that are greater than 14,000 pounds GVWR, must be compliant with the California Truck and Bus Regulation in order to receive a full incentive amount. In cases where the old school bus is not compliant, a $20,000 incentive deduction will be applied per non-compliant school bus. Review the School Bus Fact Sheet on the Truck & Bus Regulation for detailed information: Truck & Bus Regulation – School Bus Requirements (ca.gov). Applicants will be asked to provide a self-certification that the school bus(es) are compliant. To maintain compliance with the CA Truck and Bus Regulation, school buses must have a diesel particulate filter (DPF) installed or operate less than 1,000 miles per calendar year (low use).  

A lienholder will not prevent an eligible applicant from applying, however it can slow down the approval process significantly and, in some cases, can even prevent an applicant from receiving funding.  Removing the lienholder can be a time-consuming process.  Please refer to the State of California Department of Motor Vehicles website to learn more.  

The old school bus must have a current California Highway Patrol Safety Certification (CHP 292 or equivalent) at time of Application Part A submittal. A non-certified school bus will not be able to continue within the application process.   

New school buses must have Vehicle-to-Grid (V2G) functionality via use of type 1 combined charging system (CCS). This enables the new bus to engage in bi-directional charging capabilities such as storing and discharging electricity at a rate of at least 60kW, though there is no specific requirement for the purchaser’s utilization of this technology.    

Upon approval of Application Part C, a grant agreement will be issued to the applicant. After the grant agreement is fully executed, the applicant will have 10 business days to sign and submit a purchase order or other binding agreement for the new school bus(es).  

Generally, funds administered by local air districts or local municipalities, such as AB 923 funds, may be combined with ZESBI funding. Applicants may stack ZESBI funding with certain state funds only if the LEA has a small fleet. Some federal funding may be stacked with ZESBI. If an applicant chooses to stack with another incentive program, the LEA is responsible for ensuring that the other incentive program allows stacking with ZESBI and that all requirements of ZESBI and the other program are met. 

ZESBI can be stacked with these funding programs administered by local air districts or federal entities with no restrictions on fleet size. Examples of stackable local and federal programs include: 

• Federal Diesel Emissions Reductions Act State Grants or Rebates 
• AB 923 Funds 
• Sacramento Metropolitan AQMD’s Sacramento Emergency Clean Air & Transportation Grant Program (SECAT) 
• South Coast AQMD’s Mobile Source Air Pollution Reduction Review Committee (MSRC) grants 
• Bay Area AQMD’s Mobile Source Incentive Fund and Transportation Fund for Clean Air 

ZESBI funding may be stacked with these state-funded incentives administered by local air districts only if the LEA has a fleet size of 20 vehicles of fewer: 

• Carl Moyer Memorial Air Quality Standards Attainment Program (Carl Moyer Program) 
• Community Air Protection Incentives to Reduce Emissions in AB 617 Communities 

ZESBI funding cannot be stacked with either the EPA Clean School Bus Program or the EPA Clean Heavy-Duty Vehicles Program. 

ZESBI participants may utilize the Department of General Services (DGS) Statewide Procurement Contract (Bulletin #: K-73-23). The Statewide Procurement Contract includes zero-emission school buses Type A, Type A with a cutaway chassis, Type C and Type D. Use of the DGS Statewide Procurement Contract is encouraged, but not required to receive ZESBI funding. To learn more about this opportunity, please go to: https://californiahvip.org/wp-content/uploads/2024/04/DGS-Statewide-Contract-Guide-Final.pdf

ZESBI participants may combine ZESBI funding with United States Internal Revenue Service (IRS) Tax Credits, such as the Qualified Commercial Clean Vehicle Credit. Tax-exempt organizations that buy a qualified commercial clean vehicle may qualify for a clean vehicle tax credit of up to $40,000 under the Internal Revenue Code (IRC) 45W. The tax credit is available for the year that the vehicle is put in service. The tax credit is for qualified commercial vehicles acquired after December 31, 2022, and before January 1, 2033.  For more information, please visit https://www.irs.gov/credits-deductions/commercial-clean-vehicle-credit.   

ZESBI participants can also claim up to a $100,000 tax credit for infrastructure through the Alternative Fuel Vehicle Refueling Property Credit (IRS Section 30C). For more information, please visit: Alternative Fuel Vehicle Refueling Property Credit | Internal Revenue Service (irs.gov) or contact the IRS directly.  

It is imperative to the success of your project to provide timely responses to the ZESBI Team. The quicker applicants can resolve questions and/or document corrections, the quicker projects can move forward. Applicant correspondence from the ZESBI Team is sent from the CALSTART School Bus Team ([email protected]).  Please make sure to add this contact to your email to ensure you do not miss any correspondence.  

If at any stage in the ZESBI application or funding process, an applicant ceases to respond to CARB or its administrators for a period beyond 10 business days, funding may be cancelled and reallocated to another applicant.
