Claim:
1. A solar thermal power system, comprising: a solar receiver configured to heat a thermal energy storage fluid; a thermal energy storage arrangement comprising: a steam generator arrangement comprising at least an economizer section, an evaporator section, a superheater section and a reheat section communicably configured to utilize the heat of the hot thermal energy storage fluid from the hot storage tank to generate and supply steam to a steam turbine; and a bypass line having a first end and a second end, the first end of the bypass line located in a down corner upstream of the hot storage tank, the bypass line flowing through the reheat section, the second end of the bypass line located between the superheater section and the evaporator section to supply the hot thermal energy storage fluid directly from the solar receiver to the steam generator arrangement during day times when the solar receiver and the steam generator arrangement are both in operating mode, thereby recovering stored potential energy available in a down corner hot thermal energy storage fluid from the solar receiver to force the hot thermal energy storage fluid through the bypass line to the steam generator without assistance from a pump.
