Situated near Lake Mývatn in northeast Iceland, Bjarnarflag Geothermal Station is the smallest power station owned by Landsvirkjun. To generate its 3 MW of electrical energy, the station uses steam from the geothermal field by Námafjall.
Laxá Power Company had the station built in 1969, and Landsvirkjun acquired it on 1 July 1983, when Laxá Power Company merged with Landsvirkjun. Furthermore, the steam supply system at Bjarnarflag was bought by Landsvirkjun from the State Geothermal Services; this system provides not only Bjarnarflag Geothermal Station with steam to produce electricity, but also supplies steam for example to the Kísiliðjan Diatomite Plant and the Mývatn district heating system.
The energy generated by the Bjarnarflag station amounts to approximately 18 GWh per year.
