Grants for Locomotives, Marine Vessels, Stationary Equipment, and Non-Road Equipment
The Emissions Reduction Incentive Grants Program (ERIG) provides funding to repower or replace older locomotives, marine vessels, stationary equipment, and non-road equipment to reduce nitrogen oxides (NOx) emissions in Texas.
Now Accepting Applications
We are accepting applications for grants through 5 p.m. CT, Sept. 4, 2026.
This is a competitive grant based on criteria described in the Request for Grant Applications (RFGA) below.
How to Apply
Step 1 Determine if you are eligible
Eligible applicants
Individuals, state and local governments, corporations, or any other legal entity.
Eligible projects
Replace or repower:
- locomotives
- marine vessels
- stationary equipment
- select non-road equipment*
*Note: Non-road equipment types included in the Rebate Grants program are not eligible for the ERIG Program during this grant round.
Refueling infrastructure option
Applicants may request additional funding to install onsite refueling infrastructure in conjunction with eligible equipment powered by the same alternative fuel within the same application. Eligible alternative fuels for additional funding are:
- electricity
- hydrogen
- compressed natural gas (CNG)
- liquefied natural gas (LNG)
- liquefied petroleum gas (LPG)
- methanol

Step 2 Determine your emissions
Find the emission standard for the equipment you want to replace or repower using the applicable equipment table.
Emission Standards
Use the following resources to help determine the engine family code and emission standard for your equipment:
Step 3 Estimate your grant amount and learn how competitive your application may be
An applicant may request up to 80% of the incremental cost associated with the purchase or lease of the replacement equipment. The incremental cost is the eligible cost to purchase the replacement equipment minus the scrap value of the equipment being replaced.
Grant amounts cannot exceed the cost per ton (CPT) of NOX emissions reduced as specified below:
- $35,000 for non-road and stationary equipment
- $20,000 for marine vessels
- $20,000 for locomotives
Projects with the lowest CPT of NOX emissions reduced and highest reduction in total NOX emissions will be the most competitive. Use the grant estimators and technical supplements provided below to estimate your project CPT of NOX reduced and total projected NOX emissions reductions to determine how competitive your application may be.
Please Note: TCEQ will compute the final CPT of NOX reduced and total projected NOX emissions reductions based on information you enter in the project application. The estimator is used to help you determine how competitive your application may be but will not necessarily match the final CPT of NOX reduced and total projected NOX emissions reductions for your project.
