Iran’s first 5 MW geothermal energy plant

Iran is going to run the first 5-megawatt geothermal energy plant in northwestern part of the country. Iran’s first geothermal energy pilot plant would be built in Meshkin-Shahr town–northwestern Iran. Its wells have been drilled and Iran plans to establish the first 5-megawatt power plant on one of the wells.

Also Iranian engineers have drilled a 35-km deep well in Sabalan mountains – located in northwestern Iran to use geothermal sources.

Most power plants—whether fueled by coal, gas, nuclear power, or geothermal energy—have one feature in common: they convert heat to electricity. Heat from the Earth, or geothermal — energy is accessed by drilling water or steam wells in a process similar to drilling for oil.

Geothermal power plants have much in common with traditional power-generating stations. They use many of the same components, including turbines, generators, transformers, and other standard power generating equipment. While there are three types of geothermal power plants.

There are three geothermal power plant technologies being used to convert hydrothermal fluids to electricity which are dry steam, flash, and binary cycle. The type of geothermal power plants depends on fluid (whether steam or water) and its temperature.

Flash steam plants are the most common type of geothermal power generation plants in operation today. They use water at temperatures greater than 360°F (182°C) that is pumped under high pressure to the generation equipment at the surface.

Binary cycle geothermal power generation plants differ from Dry Steam and Flash Steam systems in that the water or steam from the geothermal reservoir never comes in contact with the turbine/generator units.
