A method and system for augmenting the output of a combined cycle power plant having a gas turbine driving a generator, a heat recovery steam generator that recovers exhaust heat from the gas turbine to drive a steam turbine also driving a generator, and a refrigeration element that is powered by available energy in steam exhausted from the steam turbine to cool water. The refrigeration element employs a substantially closed cycle refrigeration system that, in a preferred embodiment, is either an absorption chilling system or a thermal compression chilling system. The refrigeration element provides cool water to an inlet chiller arranged to chill inlet to the gas turbine to augment the power output of the gas turbine and the water is recirculated to be chilled and used again. Since the refrigeration cycle is substantially closed, little or no additional plant water consumption is imposed on the power plant.
