The figure illustrates the operating process of geothermal power plant to produce electricity.
Overall, there are five stages in the process, starting from pumping down the cold water into the geothermal zone, to producing electricity from the generator which is then sent into the electrical grid.
In the first step, cold water is pumped down 4.5 Km underground through the injection well. Next, the cold water is injected into the geothermal zone where it absorbs the heat from hot rocks and turns to hot water. Following this, the hot water enters into the production well and is pumped up to the ground and into the condenser.
At the fourth stage in the manufacturing process, steam is produced from the hot water in the condenser. After that, steam is used as a fuel in the combustion process of the turbine and produces power. Finally, the generator, which is powered by the turbine, produces electricity and then transferred to the natural grid via power lines.
