A power plant life cycle cost enhancing system for a power plant comprising: a power plant arranged to generate electricity by burning fuel; and a power plant control system including a computing device operationally coupled to the power plant , the computing device being configured to: monitor a first parameter of the power plant; receive a target load representing a desired power output of the power plant; employ a first model (2311;2312;2313) of the power plant to simulate operation of the power plant and determine output of the first model including at least a performance indicator of the power plant , an initial set point for an operating parameter of the power plant, and an estimated life cycle cost of the power plant responsive to at least the monitored parameter of the power plant ; augment the operating parameter using the output of the first model (2311; 2312;2313) responsive to a life cycle cost based objective function such that the life cycle cost based objective function is solved for reduced life cycle cost, thereby producing an augmented set point for the operating parameter; and generate at least one offer curve including a cost of power production versus power output of the power plant using the augmented set point. a power plant arranged to generate electricity by burning fuel; and a power plant control system including a computing device operationally coupled to the power plant , the computing device being configured to: monitor a first parameter of the power plant; receive a target load representing a desired power output of the power plant; employ a first model (2311;2312;2313) of the power plant to simulate operation of the power plant and determine output of the first model including at least a performance indicator of the power plant , an initial set point for an operating parameter of the power plant, and an estimated life cycle cost of the power plant responsive to at least the monitored parameter of the power plant ; augment the operating parameter using the output of the first model (2311; 2312;2313) responsive to a life cycle cost based objective function such that the life cycle cost based objective function is solved for reduced life cycle cost, thereby producing an augmented set point for the operating parameter; and generate at least one offer curve including a cost of power production versus power output of the power plant using the augmented set point. monitor a first parameter of the power plant; receive a target load representing a desired power output of the power plant; employ a first model (2311;2312;2313) of the power plant to simulate operation of the power plant and determine output of the first model including at least a performance indicator of the power plant , an initial set point for an operating parameter of the power plant, and an estimated life cycle cost of the power plant responsive to at least the monitored parameter of the power plant ; augment the operating parameter using the output of the first model (2311; 2312;2313) responsive to a life cycle cost based objective function such that the life cycle cost based objective function is solved for reduced life cycle cost, thereby producing an augmented set point for the operating parameter; and generate at least one offer curve including a cost of power production versus power output of the power plant using the augmented set point. <EOS>
