An apparatus for increasing the efficiency of a multi-heat source power plant includes a thermal collector having access to heat from a solar collector as a heat source for heating a fluid to a first temperature; a second heat source for heating the fluid; a heat exchanger that transfers heat to the fluid which is heated to said first temperature, to raise the temperature of the fluid to a higher temperature; and a power generation cycle using the fluid, heated to the first temperature, as a motive fluid.

Multi-heat source power plant

For operating a multi-heat source power plant, including a thermal collector having access to heat from a solar collector as a first heat source for heating a first fluid to a first temperature, a topping power generation cycle using the first fluid as a motive fluid, and a geothermal second heat source for heating a second motive fluid, which is different from said first motive fluid, to a second temperature lower than the first temperature, a heat exchanger transfers heat from the first fluid to the second fluid to raise the temperature of the second fluid to a higher temperature. A bottoming power generation cycle uses said second fluid, heated to the higher temperature, as a motive fluid.
