Efficiency of the thermal plant depends on three factors, they are

1. pressure of steam entering the TURBINE
2. temperature of the steam entering the turbine
3. pressure in the condenser

Thermal efficiency increases with increase in temperature and pressure of the steam entering the turbine. For this reason high temperature and pressure are used. Thermal efficiency is EFFECTIVELY increased by decreasing the pressure in the condenser, so pressure in the condenser is KEPT as low as POSSIBLE.

Thermal efficiency also increases by REHEATING the steam between turbine stages.
