Hellisheidi


 

Hellisheiði Geothermal Power PlantThe Hellisheidi geothermal power plant is a flash steam, combined heat and power plant (CHP) located in SW-Iceland, on one of the largest wet geothermal systems (high-enthalpy) in Iceland.  The plant’s purpose is to meet increasing demand for electricity and hot water for space heating.  Development plans call for incremental or phased expansion from 2006 to 2010 to an estimated maximum output of 300 MWe and 400 MWth, making it the largest geothermal combined heat and power plant in Iceland. The plant owner is Reykjavik Energy.

The first phase included two high-pressure 45 MWe turbines that went online in October, 2006 and then one low pressure 33 MWe turbine went online in Fall, 2007.  The most recent expansion phase consisted of two additional 45 MWe turbines that went online in Fall, 2008. The next expansion phase will be the first stage of the thermal power plant scheduled for 2010 and 2 x 45 MWe turbines in 2010.
