The current gas turbine technology always emphasize to achieve higher efficiency. This paper presents a comparative analysis for 3 (three) techniques in gas turbine system which are Combined Cysle and CHAT (Cascade Humidified Advanced Turbine) technology and as complement to Simple Cycle related to change of outputs power caused by loads change, change of huge inputs air temperature, change of gas turbine location altitude, and emission problem of NOx. The emission that produced by CHAT technology is very low, beside that it does not require SCR (Selective Catalytic Reduction) at exhaust. Therefore, CHAT technology can be located closed to customer, so its proper to overcome the distrance problem when electric energy supplie d to customer. Beside those advantages,CHAT technology has several of deficiency. CHAT technology is only ideal to supply electrical loads at small industrial estate, where the center of loads is located not far from power plant system and its only ideal to supply electrical loads at small industrial estate, where the center of loads is located not far from power plant systemn and its only used to supply the stand-alone loads with slowly demand growth or operated as standby generator sets.
