How Do I Know if I Am Eligible for a Grant?

This tab lists general eligibility critieria for the TCFP. Interested applicants should read the Request for Grant Applications (RFGA) before applying for a grant.


Read the RFGA

  • Any person or entity who owns, leases, or commercially finances a fleet of 75 or more on-road vehicles that:
    • are currently registered in Texas; and
    • includes at least 10 on-road diesel vehicles.
  • Eligible applicants include individuals, corporations, organizations, governments or governmental subdivisions or agencies, business trusts, partnerships, associations, or any other legal entity.
  • Eligible applicants must also have the legal authority to destroy the vehicle(s) being replaced.

Applications may be submitted under the TCFP to replace existing diesel-powered light-duty or heavy-duty motor vehicles with qualifying hybrid or alternative fuel vehicles. At a minimum, this includes replacing at least 10 diesel-powered vehicles.

Vehicles being replaced must be:

  • diesel-powered light-duty or heavy-duty motor vehicles;
  • owned, leased, or otherwise commercially financed by the applicant for the last two years;
  • registered in Texas for the last two years;
  • operated for at least 75% of its annual use in Texas for the last two years; and
  • certified in good operating condition with at least two years of remaining useful life (shown by current safety inspection & certification of vehicle condition signed by an independent service agent).

Replacement vehicles must be:

  • New and certified to the current federal emissions standards applicable to that vehicle and/or engine;
  • The same type, within the same weight classification, and the same body and axle configuration as the vehicle being replaced;
  • Configured and intended for use in the same application or vocation as the vehicle being replaced;
  • Certified to emit at least 25% less NOx than the vehicle being replaced; and
  • A hybrid vehicle or fueled by an alternative fuel:
    • Electricity
    • Compressed Natural Gas (CNG)
    • Liquefied Natural Gas (LNG)
    • Hydrogen
    • Propane (LPG)
    • Methanol, 85% by Volume (M85)

At least 25% of the replacement vehicles annual use must occur in one or more of the eligible counties. Regardless of the usage percentage committed to by the applicant, at least 75% of the replacement vehicle’s annual use must be in Texas.

The grant recipient must agree to monitor the use of the grant-funded vehicles for five years, and provide annual reports on the use of the grant-funded vehicles to the TCEQ.
