The achievement of life cycle assessments of energy systems with both maximum power output and economical profits is considered as the main objective of operations management. This paper aimed to evaluate both of the performance of a gas turbine using an inlet air cooling system as well as its life cycle cost. Accordingly, a thermodynamic model and an economic model are developed respectively to derive an analytical formula for calculating the cooling loads and life cycle cost. The major results show that, the output power of gas turbines power plant with a cooling system is (120MWh) which is higher than that of gas turbines power plant without the cooling system (96.6 MWh) at peak condition; while the life cycle cost is lower in the case of gas turbines power plant with cooling system. Thus, the proposed methods show a potential cost reduction and achievable through changing the structure of the system.
