Estimator for Non-Road and Stationary Equipment and Engines

For the Emissions Reduction Incentive Grants Program (ERIG). Estimate your reduction in NOx emissions and discover how competitive your grant application might be.

Instructions

For each piece of equipment or engine you would like to replace, use this estimator to determine the:

  • cost per ton of NOX emissions reduced, and
  • total reduction of NOX emissions.

This tool provides estimates based solely on the information you submit. We compute the final values.

Should you have a scenario that this estimator does not address, please email terp@tceq.texas.gov.

Data You’ll Need

Look up the following information in the Technical Supplement for Non-Road and Stationary Equipment:

  • engine load factor
  • family emission limit (optional)
  • hours per year the equipment or engine is used

You may also use the technical supplement to calculate emissions reductions and cost per ton.

Example for Multiple Pieces of Equipment or Engines

You are requesting $30,000, $35,000, and $45,000 to replace three 2002 diesel engines with newer, cleaner diesel equivalents. The old and new engines are rated at 75 horsepower and operate 95% of the time in an eligible county.

This will reduce the NOX emissions by 1.9041 tons per engine. Divide the total amount you requested, $110,000, by your total reduction of NOX emissions, 5.7123 tons. This results in a cost per ton of $19,256.69.

$110,000 ÷ 5.7123 tons = $19,256.69 per ton

About This Grant

Visit the ERIG Program webpage for more information on eligibility and how to apply.

Enter Your Information

Old Engine

For more information about load factors, see the technical supplement.

Unless you enter a family emission limit for this engine, the estimator will use the standard emission rate for the horsepower category of your engine, when available. Many engines do not have a family emission limit. See the technical supplement for information about family emission limits.

New Engine

Contract Length, Engine Usage, and Time in Eligible Areas

These counties use a different formulation of diesel fuel that the estimator will consider in the calculations.

Requested Grant Amount

Note: An applicant could receive less money than they request if the application does not meet the $35,000 cost per ton requirement or the 80% incremental cost limit.
