System and method for use in a combined cycle or rankine cycle power plant using an air-cooled steam condenser

A system for use in a combined cycle or rankine cycle power plant, the power plant comprising:

• a steam source which generates steam during operations thereof;
• and
• at least high and low pressure steam turbines, each of which is configured to fluidly receive the generated steam, the low pressure steam turbine being further configured to output first and second steam supplies, and the system comprising:
• an air-cooled condenser configured to fluidly receive and to air-cool at least the first steam supply via a supply of air;
• a cooling tower from which a first water supply is cycled;
• a chilling coil through which a second water supply water is cycled to thereby cool the supply of air;
• and
• a vapor-absorption-machine (VAM) configured to fluidly receive the second steam supply and the first water supply by which a refrigeration cycle is conducted to thereby cool the second water supply.
