Orka náttúrunnar

ON Power (Icelandic: Orka náttúrunnar), is an Icelandic power company, headquartered in Reykjavík, that produces and sells electricity to industry and households by harnessing renewable, mainly geothermal, resources. ON Power also provides water for space heating in Reykjavík and surrounding areas. Traditionally, ON Power´s main service area is Reykjavík and surrounding areas in the south-west part of Iceland, although households and businesses can buy electricity from any supplier in Iceland, regardless of location.

ON Power was founded on 1 January 2014 as a subsidiary of Reykjavik Energy - which is owned by the city of Reykjavík and the municipalities of Akranes and Borgarnes. To comply with Icelandic law no. 65/2003 that effectively call for the de-regulation of the Icelandic electricity market, Reykjavik Energy moved its production and sales of electricity - including power plants - into the ON Power subsidiary.

ON Power owns and operates the Nesjavellir and Hellisheiði Geothermal Plants. The plants provide electricity and hot water to industry and households in Iceland. 99% of housing in the Reykjavík area is space-heated with hot water provided by geothermal sources. Both plants are situated in the Hengill region; an active volcanic ridge in the south-west part of Iceland. ON also operates the Andakílsárvirkjun hydrostastion, situated in Borgarfjörður.

The Nesjavellir Geothermal Plant has been operating since 1990 and the Hellisheiði Plant since 2006, with a combined output of 423 MWe and 433 MWth. The Andakílsárvirkjun has been operating since 1947 and has a total output of 8 MWe. The Elliðaár hydrostation - commissioned in 1921 - was operated by ON (and Reykjavik Energy prior to that) until 2013 when Icelandic laws 104/2001 declared the station, including machinery and pipelines, a historic preservation. As a result, the Elliðaár station was decommissioned.
