Step 3 Estimate your potential grant amount (replacement or repower projects only)

Though not required, we recommend you use the grant estimators or technical supplements below to estimate your cost per ton of nitrogen oxides (NOx) reduction and determine how competitive your application may be. Projects with a lower cost per ton to reduce NOx and with higher reductions in total NOx emissions will score more points than other projects.

TCEQ will verify your estimates and make the final calculations for your application.
