In the present work, a life cycle oriented approach is used for designing power plants in a way they can satisfy the desired demand along the whole time horizon, while selected economic indicators of the project are optimized. As case study, optimal design characteristics as well as optimal values of long term operation parameters of a GT + 1PSH HRSG Type CCGT power plant (GT: gas turbine, 1PSH: 1 pressure with superheater, HSRG: heat recovery steam generator, CCGT: combined cycle gas turbine) are obtained by means of a multiperiod mathematical model, seeing that the net present value of the facility is maximized. In addition, advantages of the life cycle oriented approach are discussed when compared with a power plant design obtained by traditional methods.GT: gas turbine, 1PSH: 1 pressure with superheater, HSRG: heat recovery steam generator, CCGT: combined cycle gas turbine) are obtained by means of a multiperiod mathematical model, seeing that the net present value of the facility is maximized.
