The method comprises the steps of (a) compressing a first refrigerant in a first compressor 5 driven by a first gas turbine, said first gas turbine having a first inlet air stream and a first exhaust stream; (b) recovering heat from the first exhaust stream in a waste heat recovery unit to produce a heated circulating fluid stream; (c) circulating at least a portion of the heated circulating fluid stream through a chilling circuit to produce a chilled coolant stream; and, (d) directing at least a portion of a chilled coolant stream to a first inlet air 10 cooling circuit to cool the first inlet air stream.1/6 0
