besar daripada model konfigurasi HRSG 2PRH, model konfigurasi HRSG
mempengaruhi nilai NPV, semakin besar nilai efisiensi termal dan kapasitas daya
pembangkit listrik maka nilai NPV akan semakin besar, model konfigurasi HRSG
1PRH dengan interest rate 8.4% mempunyai PBP selama 8 tahun, sedangkan model
konfigurasi HRSG 2PRH dan 3PRH mempunyai PBP selama 7 tahun, dan nilai tukar
mata uang dan harga bahan bakar memiliki nilai sensitivitas yang tinggi terhadap
nilai keekonomian apabila dibandingkan dengan nilai suku bunga bank dan biaya

In order to get the comparison of thermalefficiency, power capacity, LCOE (Levelized Cost of Electricity) and the economicvalue with approach NPV (Net Present Value), IRR (Internal Rate of Return), PBP(Pay Back Period), and economic sensitivity of each HRSG configuration models.The influence of the HRSG 1P (one pressure), 2P (two pressure) and 3P (threepressure) with the exit turbine gas temperature, the economic analysis of thecomparison HRSG 2P, 3P, and 3PHR (three pressure with reheater), and irrevesibelanalysis of the three-pressure HRSG with reheating and cooling air to the gasturbine on CCGT have been investigated.
