In a method of operating a power station plant, which consists of a gas-turbine group (I), a steam-generating stage (II) consisting of a waste-heat steam generator (15), and a steam cycle (III), a liquid quantity increased above 100% circulates in a heat-exchange stage (15a), operating in the low temperature range, of the waste-heat steam generator (15). The portion above 100% of this liquid quantity is diverted at the end of said heat-exchange stage (15a) and is evaporated in at least one pressure stage (26). Steam (37) arising herein is then fed to a steam turbine (17) at a suitable point. A still hot liquid quantity (36) from the pressure stage (26) is fed into a feed-water tank and deaerator (22), and steam (33) arising herein is fed to a further steam turbine (18) at a suitable point.
