The country of Iran is planning its first pilot geothermal power plant, a 5 MW plant to be built in Meshkin Shahr town in northwestern Iran.

Iranian news report that the country is planning its first geothermal power plant. The 5 MW plant would be a pilot plant to 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 (must be 3.5km?) well in Sabalan mountains – located in northwestern Iran to use geothermal sources.

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.”

It is not reported what temperatures are expected to be found and what technology the plant now planned would be utilizing.
