Nesjavellir Geothermal Power Station

The Nesjavellir Geothermal Power Station is the second-largest geothermal power station in Iceland. The facility is located 177 m above sea level in the southwestern part of the country, near Thingvellir and the Hengill Volcano. NGPS is owned and operated by ON Power.

Plans for utilizing the Nesjavellir area for geothermal power and water heating began in 1947, when boreholes were drilled to evaluate the area's potential for power generation. Research continued from 1965 to 1986. In 1987, construction of the plant began, and the cornerstone was laid in May 1990. The station produces approximately 120 MW of electrical power; it also delivers around 1,100 litres of hot water 82–85 °C per second - with a heating capacity of 150 MWt, serving the space heating and hot water needs of the Capital Region.
