Technical FAQs 4

How many hydro power plants are in Iceland?

Iceland generates hydro-powered energy from 14 hydro power plants across the country. In total, these hydro power plants has a capacity of 1912.6 MW. What is hydropower? Hydropower, also known as hydroelectric power, is a form of renewable energy that generates electricity by harnessing the power of moving water.

Where is the largest hydroelectric power station in Iceland located?

For now, the largest power station in Iceland is Kárahnjúkar Hydropower Plant. It generates electricity in the north Vatnajökull area, which is needed for aluminum production. Historically, all the hydroelectric power stations are run by Landsvirkjun, the National Power Company of Iceland.

What was the initial purpose of Iceland's first hydropower station?

Iceland's first hydropower station was built in Hafnarfjörður in 1904. It produced enough power to light 15 houses and 4 street lamps. By 1937, electricity produced from hydropower replaced imported coal in Reykjavik. By 1950, there were 530 small power stations around Iceland.

When was the first hydropower plant built in Iceland?

The first hydropower plant in Iceland started operation in 1904 in Hafnafjörður. Reykjavík saw its first hydropower plant set up in 1921 and Akureyri in 1922. With these plants, the electricity market in Iceland was created.
