Plans for utilizing the Nesjavellir area for geothermal power and water heating began in 1947. Researches continued from 1965-1986. In 1987 the construction of the plant began and the cornerstone was laid in 1990.
The station produces approx. 120 mw of electrical power and delivers around 1800 liters of hot water per second.
Nesjavellir geothermal plant is situated in Hengill. The mountain is situated on an active volcanic ridge, making the whole area a geothermal hotspot. The power station is the second largest geothermal power plant in Iceland and is situated 177 m. above sea level.
