Hellisheidi (Hellisheiði) Power Plant

Hellisheidi (Hellisheiði) Power Plant

Hellisheidi is a lava-clad plateau separating the capital from the southern lowlands, Iceland’s most important farming area. 

The heath is covered with many layers of lava, the youngest about 1000 years old. 

As you cross them, notice the row of cairns snaking into the distance – they marked the original horse trail across the plateau before the road was built. 

You'll also notice columns of steam and a network of pipes as the futuristic Hellisheidi Power Plant comes into view. Over 90% of houses in Iceland and 99% of Reykjavik homes are heated by geothermal water and those interested in learning more about the processes involved in harnessing it can visit the power station.

Owned by ON Power, the plant generates 303 MW of electricity from 7 turbines and produces 133 MW of hot water. 

The process is renewable and run-off water is injected back into the bedrock. 

Inside the power plant, visitors can see the turbines, watch a short film explaining the process and try out an earthquake simulator. 

There is a small entrance fee. 

Toilets and a cafe are on site.
