The Geothermal Energy Exhibition at Hellisheidi Power Plant is a state-of-the-art look into the harnessing of geothermal energy in Iceland. ON Power owns the Power Plant. It is a striking example of how Iceland harnesses geothermal energy in a sustainable manner.

Of the six geothermal power plants in Iceland, Hellisheiði is the newest and largest. Hellisheidi Power Plant is situated in the Hengill area in South Iceland and provides electricity and hot water for space heating in the industrial and domestic sectors in Iceland.

To access the potential energy under the surface, wells reach thousands of meters into the ground, penetrating reservoirs of pressurized water. Heated by the Earth’s energy, this water can be more than 300°C in temperature. When released the water boils up from the well, turning partly to steam on its way. At Hellisheidi, the steam is separated from the water to power some of the plant’s seven turbines. Further depressurized the remaining water creates more steam and powers the other turbines. At its maximum output the station can produce 303 MW of electricity. Therefore the plant is one of the largest single unit power plants in the world.

What tours are available?

Hellisheiði Power Plant is located only about 20 minute drive from Reykjavík, in a stunning setting surrounded by lava and moss which makes the experience all so much stronger.

Guests of all ages can enjoy themselves at The Geothermal Energy Exhibition. Interactive multimedia installations and wall displays present the exhibition. It allows visitors to examine Iceland‘s geothermal energy utilization in a clear and illuminating fashion.
