[1] The facility is located in Hengill, southwest Iceland, 11 km (7 mi) from the Nesjavellir Geothermal Power Station.

The plant has a capacity of 303 MW of electricity and 200 MWth of hot water[2] for Reykjavík's district heating.

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.

The program was expected in 2017 to cost 19 billion Icelandic crowns to maintain a steady electric output.

It was partially funded by the European Union's Horizon 2020 program, and captures up to 4,000 metric tons of carbon dioxide each year.
