The Geothermal Energy Exhibition at Hellisheidi Power Plant is a state-of-the-art look into how Icelanders harness geothermal energy. ON Power owns the Power Plant. The power plant is a striking example of  how Iceland provides sustainable energy.

Of the six geothermal power plants in Iceland, Hellisheidi is the newest and largest. The Power Plant sits in South Iceland and provides homes and businesses with electricity and hot water for space heating.

In order to reach the geothermal energy, Icelanders have built wells reaching thousands of meters into the ground that penetrate reservoirs of pressurized water. Heated by the Earth’s energy, this water can be more than 300°C (572°F)  in temperature. When released, the water boils up from the well and turns partly to steam on its way. The Hellisheidi power plant separates the steam from the water to power some of the plant’s seven turbines. The remaining, depressurized water creates more steam and powers the other turbines. At its maximum output, the station can produce 303 MW of electricity. Altogether, the plant is one of the world’s largest single unit power plants.

Visiting the Hellisheidi Power Plant

Hellisheidi Power Plant is located just a 20-minute drive from Reykjavík. The building sits in a stunning setting surrounded by lava and moss.

Guests of all ages can enjoy themselves at The Geothermal Energy Exhibition. Interactive multimedia installations and wall displays explain about geothermal energy in a clear and fun way. Visitors can also see how the city of Reykjavik uses the geothermal energy.  They can also look through a window into the power plant itself to see the massive machinery.

The tour is self-guided with an audio guide in various languages.  The center can also set up tours for groups led by an English-speaking guide.  The center also has a coffee shop with a great view of the area, as well as a quality souvenir shop.
