1. A LNG/LPG combined cycle power plant comprising:

  • a cold liquid storage tank for storing LNG/LPG;

    a cold liquid vaporizer for receiving LNG/LPG from the cold liquid storage tank and vaporizing LNG/LPG;

    a circulating primary heat transfer fluid for supplying heat to the LNG/LPG vaporizer to assist in vaporizing LNG/LPG wherein the heat transfer fluid is chilled;

    a gas turbine having a cooling coil wherein the cooling coil receives the chilled primary heat transfer fluid to increase the output and efficiency of the gas turbine; and

    a circulating water/heat transfer fluid (HTF) heat exchanger for receiving the primary heat transfer fluid from the gas turbine cooling coil and placing the primary heat transfer fluid in heat exchange relationship with a secondary heat transfer fluid wherein the primary heat transfer fluid is warmed and returns to the vaporizer.
