TIC Comparison Calculator

This TIC Comparison Calculator can be used for making only preliminary estimates of net capacity enhancement by TIC and the associated costs. The calculator is based on several rules of thumb. More accurate calculations may require hourly weather data for 8,760 hours of the year, detailed combustion turbine modeling and site-specific cost analyses (including hourly market value of electric energy). Read this additional information about the calculation of power capacity enhancement and economics.

Note: All data should be entered without "%"s or "$"s and without units. Examples: 50% should be entered as 50, .08% as .08, $5.00 as 5.00, etc..
