Enex specializes in geothermal binary power plant development, project management and consulting, established to export geothermal knowledge, with reliance on comprehensive know-how and operational experience from the Icelandic geothermal industry. The Icelandic geothermal industry produces more than 570 MW of power from geothermal energy and over a 1300 MW for heating and industrial usage. The Icelandic geothermal industry is a mature and experienced, since the country began using geothermal for heating in the 1930's and since then it has grown slowly but surely, phasing out more expensive and polluting fossil fuel in the heating and energy sector. These are the major geothermal power plants in Iceland:

Nesjavellir Combined Heat & Power Plant
Nesjavellir geothermal power plant is situated in the Hengill area, which is a high-temperature area in Iceland. The plant itself generates 120 MWe and delivers 300 MWth as heat to the Icelandic capital of Reykjavik, 27 km away. The plant owner and operator is Reykjavik Energy. The construction of the Nesjavellir Power Plant began in 1987 and was formally started in 1990. Today it is a part of the largest and most modern geothermal district heating system in the world and Iceland's largest geothermal combined heat and power plant (CHP). A total of 25 wells have been drilled in the Nesjavellir area at depth ranging from 1000 - 2200 m and temperatures as high as 380°C have been measured. Nesjavellir plant will likely be enlarged by 45 MWe by the end of 2010.
Krafla Geothermal Power Plant
Krafla was a pioneer geothermal power plant in Iceland as the project started 1974. It was then the largest power plant in Iceland. It is now producing 60 MWe with two steam turbines. Recent research on the steam field suggest there is ample steam to expand the Krafla station beyond the 60 MWecapacity originally envisaged for it. At full capacity the station utilizes 110 kg/sec of 7.7 bar saturated high-pressure steam and 36 kg/sec of 2.2 bar saturated low-pressure steam. The plant owner and operator is Landsvirkjun.
Svartsengi Combined Heat & Power Plant
The Svartsengi Geothermal Power Plant now reaches a capacity of 75 MWe and 150 MWth. The total installed power consists of three individual steam turbine systems of 30 MWe respectively 8 MWe and a total of 7 ORC bottoming units. The Svartsengi Power Plant is connected to the Blue Lagoon geothermal spa, which is scientifically recognized for its skin healing power, using the geothermal seawater from the plant which contains active ingredients from this unique geothermal heat & power plant. The plant owner and operator is HS Orka.
Reykjanes Geothermal Power Plant
The Reykjanes Power Plant is located on the Reykjanes peninsula in Iceland. The plant uses steam from a reservoir measuring temperatures up to 320°C. This is the first time that geothermal steam of such high temperature has been used for electrical generation. It can therefore be said that this is a pioneer project in the world geothermal industry. The plant also operates Fuji turbines that have the highest intake pressure of any geothermal power plant in the world. The Reykjanes Power Plant produces 100 MWeusing two 50 MWe steam turbines. The plant owner and operator is HS Orka. » more
Hellisheidi Combined Heat & Power Plant
In construction is a 300 MWe and 400 MWth geothermal power plant in Hellisheidi, Iceland. The new geothermal plant provides Reykjavik with electricity and space heating as the demand is increasing, especially industrial demand. The production will be increased incrementally from 2006 until 2012. The plant owner and operator is Reykjavik Energy. The first phase, with electrical output of 90 MWe, was completed in October 2006. A 33 MWe low-pressure turbine was commissioned late 2007. Another 90 MWe will be added in 2008. 21 wells have already been drilled in the Hellisheidi area for exploration and harnessing of the available geothermal energy. The production of hot water for Reykjavik´s district heating system is scheduled to start in 2009. The produced amount of hot water is said to suffice the system until 2020. » more
Bjarnarflag Geothermal Power Plant
A small steam turbine power plant with 3.2 MWe power, which also delivers industrial steam to a nearby Silicium Plant. Bjarnarflag Power Plant was the first geothermal power plant in Iceland.The plant owner and operator is Landsvirkjun. Plans are to expand this steam field by building a new modern 40 MWe geothermal power plant in combination with a visitor tourist centre, outdoors-bathing facilities and sauna, using the run off water from the power plant. Drilling of new exploration wells has already begun.
Berlin Binary (ORC) Power Plant
Salvadoran geothermal company LaGeo S.A. awarded an engineering, procurement, construction and management contract to Enex. The plant owner and operator is LaGeo. The project is a 9.3 MWe expansion to La Geo´s existing 56 MWe Berlin power plant, bringing the total installed capacity to 65.3 MWe. The plant uses 300 l/s, 180 °C brine from two separators and a wet cooling tower. The plant is in operation. » more
