the possibilities to improve the efficiency of new power units is raising the steam parameters. With improved power plant efficiency, there is a lower demand for power of almost all auxiliary equipment except the boiler feed pump. The reason for this is that the power needed to drive the feed pump is an almost linear function of the steam pressure.

This is not correct. It neglects the fact that some of the steam condenses in the turbine. For the adiabatic reversible expansion occurring in the turbine, the entropy per unit mass of the mixture of saturated liquid and saturated vapor leaving the turbine at 1 Bar must equal the entropy per unit mass of the dry saturated vapor entering the turbine at 5 bars.
