The geothermal area at Theistareykir has enormous potential for geothermal utilisation, with an estimated capacity of up to 200 MW. The construction of the Theistareykir power station with 90 MW capacity was the first step in geothermal utilisation in the area.
The construction spanned two years and was split in two 45 MW phases. The first phase commenced operations in the fourth quarter of 2017 and the entire power plant came into full operation with the second phase coming online during spring of 2018. The design and plans for the power station were centered on creating an efficient, reliable power station that respects the environment.
The power station was developed by Landsvirkjun, the country’s largest electricity generator. It is owned by the Icelandic state and generates 75% of all electricity used in Iceland; from hydro, wind and geothermal energy. Landsvirkjun operates 18 power stations in Iceland and is committed to efficient energy production, in harmony with the environment and society.
