A power plant control system determines an augmented operating parameter set point responsive to a life cycle cost (LCC) objective function responsive to a LCC model. The augmented operating parameter value may be responsive to an initial set point determined by a controls model and a performance indicator determined by a performance model. The power plant may include a thermal generator, such as a gas turbine or other fuel-burning generator, and the operating parameter may include firing temperature, fuel flow rate, steam pressure/temperature/flow rate, and/or another suitable operating parameter. An offer curve is generated responsive to the augmented operating parameter.
