1. A method of operating a geothermal power system, comprising:
producing a first fluid from a geothermal reservoir;
introducing the first fluid into a first pressure exchanger;
reducing a pressure of the first fluid in the first pressure exchanger;
conveying the first fluid from the first pressure exchanger to a heat exchanger; and
increasing a temperature of a second fluid at the heat exchanger using the first fluid.
