History

Electricity production with two turbines commenced in 2006. In 2007, an additional low pressure steam turbine of was added. In 2008, two turbines were added with steam from Skarðsmýrarfjall Mountain. The hot water plant was introduced in 2010 and the last two high pressure 45 MW turbines were added in 2011.
In order to reduce hydrogen sulphide pollution in the capital area a system was added to the plant in 2014 which reinjects non-condensable gases into the ground.

Features

The power plant offers educational tours and presentations about sustainable energy as part of its Geothermal Energy Exhibition.
A pilot direct air capture facility operated by Climeworks is co-located at this site. It was funded by the European Union's Horizon 2020 program, and captures 50 metric tons of carbon dioxide each year. The carbon dioxide is captured, injected into the ground, and mineralized.
