Editing Geothermal power in Iceland (section)

==Electricity production infrastructure==
According to the National Energy Authority of Iceland, in 2020, Iceland's geothermal facilities had in total an [[installed capacity]] of 799 [[MWe|MW<sub>e</sub>]], making up 25.9% of all power capacity in Iceland, besides hydropower, [[Wind power in Iceland|wind]], and fossil fuels.<ref name=":92" />

According to Askja Energy Partners, an energy consulting firm in Iceland, the three entities that own and operate the largest geothermal power stations in Iceland are [[HS Orka]], [[Orka náttúrunnar|ON Power]], and [[Landsvirkjun]] (National Power Company of Iceland).<ref name=":15">{{Cite web |date=2011-11-10 |title=Power Plants |url=https://askjaenergy.com/iceland-renewable-energy-sources/icelandic-power-plants/ |access-date=2022-11-04 |website=Askja Energy - The Essential Perspective on Energy in the Northern Atlantic and Arctic Region |language=en}}</ref><ref>{{Cite web |title=Landsvirkjun.com - The National Power Company of Iceland |url=https://www.landsvirkjun.com/ |access-date=2022-11-05 |website=landsvirkjun.com |language=en-gb}}</ref>

The following are nine power plants that contribute the most to Iceland's geothermal power production capacity; the ownership of each geothermal power plant is also noted:
