Þeistareykir Geothermal Station

The development of geothermal energy at Þeistareykir began as a local initiative. In 1999, municipalities and energy companies in northeast Iceland established the company Þeistareykir ehf. to explore the potential of the geothermal resources in the area. Landsvirkjun acquired a stake in the company in 2005 and gradually increased its ownership before taking over the project entirely.

Over the following years, extensive research, environmental studies and planning work were carried out to better understand the geothermal resource and how it could be developed sustainably. Construction of the power station began in 2015, marking the start of one of the largest geothermal energy projects in Iceland in recent decades.

Þeistareykir Geothermal Station was commissioned in 2017, with a second turbine unit entering operation the following year. The station consists of two 45 MW turbine units, giving it a total installed capacity of 90 MW. It was also the first geothermal power station built from the ground up by Landsvirkjun.

The Þeistareykir geothermal area is considered one of Iceland’s most promising geothermal resources. Studies indicate a long-term generation potential of up to 200 MW. From the outset, the aim has been to develop the resource responsibly while building a reliable and cost-effective source of renewable energy for the future.
