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.

Accepting Applications Soon

We expect to begin accepting applications in April 2026—subject to change.

This is a competitive grant program based on criteria described in the Request for Grant Applications.

The information below is provided for reference only. When we begin accepting applications, we will update this webpage with the final requirements and documents.

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:

  • select non-road equipment*
  • stationary equipment
  • marine vessels
  • locomotives

* 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

Review documents to ensure eligibility

Documents below are for reference only. We will provide updated documents when we begin accepting applications.

Step 2 Determine your emissions

Find the emission standard for the equipment you want to replace or repower using the applicable equipment table:

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:

  • $20,000 for marine vessels and locomotives
  • $35,000 for stationary equipment
  • $35,000 for non-road equipment

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.
