A system for planning operation of a power plant capable of a first mode driving a power generator using a turbine and a second mode not driving the power generator using the turbine over a predetermined period. A determination unit determines whether a predicted power-selling price is higher than a power generation cost; and a planning unit calculates a loss index of the first and second modes in a case where the predicted selling price is equal to the generation cost or less within the predetermined period and formulates a plan to operate the power plant in a mode having a smaller loss index. The loss index of the first mode includes a power-selling loss that is a difference between the predicted selling price and the generation cost, and the loss index of the second mode includes a loss that is caused by not driving the power generator.
