1. A performance evaluation method comprising:
a step of acquiring a sampling value of a gas turbine output and a sampling value of a steam turbine output which are measured at each time during an operation of a combined cycle power generation plant that generates power by using a gas turbine and a steam turbine; and
a step of obtaining a plant output which is a total output of the sampling value of the gas turbine output measured at a first time and the sampling value of the steam turbine output corresponding to the gas turbine output measured at the first time, the steam turbine output being measured at a second time after a predetermined delay time from the first time,
wherein in the step of obtaining the plant output,
a fixed value of the delay time is obtained, based on a plurality of the sampling values of the gas turbine output and a plurality of the sampling values of the steam turbine output.
