Step 3 Replacement or repower projects only: Estimate your potential grant amount (Optional)
Determine how competitive your application may be by estimating your cost per ton of nitrogen oxides (NOX) reduction using the grant estimators or technical supplements below. Projects with a lower cost per ton to reduce NOX and with higher reductions in total NOX emissions will score higher than other projects.
