TheHellisheiði Power Station (Icelandic:Hellisheiðarvirkjun,Icelandic pronunciation:[ˈhɛtlɪsˌheiːðarˌvɪr̥cʏn]) is the eighth-largestgeothermal power station in the world and largest in Iceland.[1] The facility is located inHengill, southwestIceland, 11 km (7 mi) from theNesjavellir Geothermal Power Station. The plant has a capacity of303MW of electricity and200 MWth of hot water[2] forReykjavík'sdistrict heating.[3] The power station is owned and operated byON Power, a subsidiary ofReykjavík Energy.

Electricity production with two45 MWturbines commenced in 2006. In 2007, an additional low pressuresteam turbine of33 MW was added. In 2008, two45 MW 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 reducehydrogen sulphide pollution in the capital area, a system was added to the plant in 2014 which reinjects non-condensable gases into the ground.[4] In 2020, the hot water production was increased to 200 MWth to meet the increaseddistrict heating demand as the capital area expands.[5]
In 2016, the operator, ON, announced a program of new drilling to deal with falling steam levels which had first become apparent in 2013. The program was expected in 2017 to cost 19 billion Icelandic crowns to maintain a steady electric output.[6]

The power plant offers educational tours and presentations aboutsustainable energy as part of its Geothermal Energy Exhibition.[7]
A pilotdirect air capture facility operated byClimeworks is co-located at this site. It was partially funded by theEuropean Union'sHorizon 2020 program, and captures up to 4,000 metric tons of carbon dioxide each year. The carbon dioxide is captured, injected into the ground, and mineralized.[8][9][10]
