Fleet Zero-Emission Resource Opportunity (Fleet-ZERO)

Colorado’s Fleet-ZERO grant program strategically addresses greenhouse gas emissions and air pollution from the fleet sector by funding electric vehicle (EV) charging to support the transition of light-, medium-, and heavy-duty fleets to electric vehicles. Fleet emissions have a disproportionate impact on public health and the environment, especially for marginalized and lower-income communities living near major roadways and facilities. The State’s Clean Truck Strategy and Community Access Enterprise identify fleet electrification as an important near term action to improve air quality and protect our environment, while also saving Colorado fleet owners and operators money on fuel and maintenance costs. 

Fleet-ZERO supports charging for fleet owners and operators seeking to electrify their vehicles, as well as public and semi-public fleet charging sites and providers offering EV charging-as-a-service to fleets. The program offers competitive grant funding with prioritized investments in disproportionately impacted communities and enhanced incentives for Qualifying Entities (please see Eligibility section below).

The current Fleet-ZERO standard application round will close on Friday, December 1, 2023 at 5:00 PM MT. The Fleet-ZERO rolling application is currently open year-round for Qualifying Entities requesting $50,000 or less in funding. Please see the Eligibility section below for more information.

All Fleet-ZERO applicants are required to read the Application Guide in full prior to submitting an application:

All Fleet-ZERO applicants must submit their application online through the grant portal:

During every standard application round, for the first two (2) weeks after the round opens, CEO will have a formal Q&A period for the Fleet-ZERO program.

CEO will post public responses to all of the questions received during the Q&A period one (1) week after the Q&A period closes. CEO will not answer questions on an individual basis during the standard application rounds. The Q&A document linked below will be updated with responses from the most recent question submission period on November 3, 2023.

NOTE: Charging for electric school buses is not eligible for Fleet-ZERO funding. For school bus charging, please apply for funding through the Colorado Electric School Bus Grant Program. Transit vehicle charging for past recipients of Colorado Department of Transportation (CDOT) Division of Transit and Rail funding is also not eligible for Fleet-ZERO funding. Funding for transit vehicle charging is available through the Clean Transit Enterprise. School district and transit agency white fleet vehicle charging, however is eligible for funding through Fleet-ZERO.

There are three application types for the Fleet-ZERO grant program:

  • Standard: Single fleet, shared fleet, charging as-a-service, public or semi-public fleet 
  • Rolling: Same eligibility as the Standard application, but available year-round solely for Qualifying Entities submitting up to $50,000 maximum funding requests
  • Medium- and Heavy-Duty (M/HD) Charging Corridors (Forthcoming): Fully- or semi-public fleet charging configured for M/HD electric vehicles

Qualifying Entities are eligible for enhanced incentives and may submit rolling applications:

  • Disadvantaged Business Enterprises (DBE) 
  • Minority Business Enterprises (MBE)

  • Tribal Entities
Eligible project costs

Funds can cover costs directly associated with the purchase and installation of EV charging equipment and infrastructure for fleets, as well as costs associated with the 5 year networking and 5 year warranty requirements for the program.

CEO will only reimburse eligible project costs that are incurred or contracted for after executing a Purchase Order or Contract with the Colorado Energy Office.

The Colorado Energy Office will outline a specific amount of funding available to applicants during each application cycle. The maximum award per applicant, per round for Standard applications is likely $250,000-500,000. The maximum award for Rolling applications is $50,000. Only Qualifying Entities are eligible to submit Rolling applications.

Match: Match requirements are subject to change. Currently, a minimum 20% match (up to the incentive maximums) is required for all non-qualifying entities. A reduced 10% minimum match (up to the incentive maximums) is required for Qualifying Entities.

Fleet-ZERO - Standard & Rolling Incentives
Power level Incentive per charger Incentive per dual port charger Vehicle class eligibility Likely maximum funding** (per applicant, per round) Enhanced incentives* (per charging port for qualifying entities)
< 19 kW $3,000 $6,000 - $250,000 +$500
19-49 kW $5,000 $10,000 *** $250,000 +$500
50-99 kW DCFC $35,000 $50,000 Class 4-8*** $500,000 +2,000
100 kW+ DCFC $50,000 $70,000 Class 4-8*** $500,000 +$2,000















Fleet-ZERO offers funding for eligible costs up to the incentive maximums included in the table above, not to exceed 80% of eligible projects costs (90% for Qualifying Entities*).

Incentives are based on charger power level and number of chargers. Charging port count is determined by the number of electric vehicles capable of being charged simultaneously per charger at the listed power level.

*Enhanced incentives are available for all Qualifying Entities, including increased maximum funding amounts per charging port (in addition to the standard incentive maximums) and a reduced minimum match requirement of 10% (instead of the standard 20%).

**The Evaluation Committee reserves the right to award more or less funding during any Standard application round. The max funding that will be awarded per Rolling application submission is $50,000.

***Based on the power level charging station(s) being requested, applicants must confirm the Vehicle Class Eligibility and the anticipated EVs’ maximum onboard EV charging capability. For 50 kW+ DCFC, funding requests seeking one (1) charger for one (1) EV should only be for Class 4 or above EVs (except in certain non-overnight charging scenarios). However, 50 kW+ DCFC are eligible to be shared amongst multiple lighter Class EVs (please see the Application Guide for more information).
