Geothermal district heating power system

A geothermal district heating (DH) system, comprising:

• a) a plurality of DH conduits, each of said conduits extending to a corresponding heat consumer;
• b) a fluid circuit through which a geothermal fluid is flowable;
• c) at least two heat exchangers, each of said heat exchangers configured to transfer heat directly or indirectly from said geothermal fluid to a first supply of DH-usable water and to a second supply of additional DH-usable water with a total heat influx provided by said at least two heat exchangers to said DH-usable water and to said additional DH-usable water that is sufficiently high to raise a temperature of said DH-usable water and said additional DH-usable water to a predetermined DH-usable temperature without need for any supplemental fossil fuel derived waste heat to be transferred to said DH-usable water and said additional DH-usable water,
• wherein a first of the at least two heat exchangers is a vaporizer for vaporizing an organic motive fluid circulating in an Organic Rankine Cycle (ORC) type power plant,
• wherein a second of the at least two heat exchangers is a heat exchanger by which said organic motive fluid at a temperature less than its temperature upon exiting said vaporizer transfers heat to said DH-usable water,
• wherein a third of the at least two heat exchangers is a water-water heat exchanger by which said DH-usable water at a temperature greater than its temperature prior to being received in said second heat exchanger transfers heat to said additional DH-usable water;
• and
• d) means for delivering said additional DH-usable water through said plurality of DH conduits.
