1. A power plant, comprising:

  • a first heat exchanger that is configured to receive LNG and to provide refrigeration to a working fluid to thereby generate heated LNG, and an expander configured to receive the working fluid to thereby drive a generator and to produce an expander discharge;

    wherein the first heat exchanger is further configured to allow heat exchange between the expander discharge and the LNG;

    a second heat exchanger that is configured to receive the heated LNG and to provide refrigeration to a heat transfer medium fluid to thereby generate vaporized LNG; and

    a third and a fourth heat exchanger, configured to receive the heat transfer medium and to provide refrigeration for an intake air cooler and a steam turbine cycle, respectively.
