This cooling equipment comprises: a refrigerant supply line (81) supplying, to a condenser (6), a condenser refrigerant which cools steam (Sb) that has driven a steam turbine (5), to return the steam (Sb) to water (W); and a cooling part (80) which is disposed on the refrigerant supply line (81), and performs heat exchange between liquefied gas used as fuel for a gas turbine (2) and the condenser refrigerant to heat and vaporize the liquefied gas and to cool the condenser refrigerant at the same time.
