The Hellisheidarvirkjun (or Hellisheidi) heat and power plant (CHP) is located at the Hengill volcano, south of Iceland. It serves electricity to the Icelandic city of Reykjavik, and is the largest power generating plant of any kind in Iceland. The construction of this plant took place in various phases. Two 45 MW turbines were first installed in 2006, followed by the addition of another 33 MW engine in 2007. Two extra turbines, each with a capacity of 45 MW, were installed in 2008, and hot water production started in the plant in 2010 when three thermal power plants were put into action. In 2011, two 45 MW turbines were added to the Hellisheidi heat and power plant, increasing its total capacity of electricity generation. Today, the power plant can produce about 300 MW of electricity in addition to 400 MW of thermal energy.
