Hydro electric power

Hydroelectric power makes use of the power capacity contained in water.

 

The power obtained from water is connected to height. To produce 1 kWh the water has to run from a 367 meter height through an engine that changes the water to electricity. This calculation does not include the amount that is lost in the engine and while the water travels – something that can not be avoided. The higher the water comes from the less of it is needed in order to produce a kWh. If the water is taken from a low height more water is needed.
 
The power in water and the need for modern equipment that runs on electricity was the reason for the creation of the power company SEV back in 1946. However, hydroelectric power had been used in most Faroese villages before this time, in the form of watermills where corn was grained. Some of these watermills are still documented. There have also been factories that have used water in order for their tools to work.
 
Two hydroelectric power plants were built prior to SEV’s birth. The municipality of Vágur built the hydroelectric power plant in Botni in 1921. It produced electricity for Vágur. The municipality of Klaksvík built the hydroelectric power plant in Strond in 1931. It produced electricity for Klaksvík.

Today, these two hydroelectric power plants have been changed a lot and they now form part of SEV’s power supply system. SEV has built three hydroelectric power plants in Vestmanna and one south of Eiði.

In total these hydroelectric power plants produce 40 % of SEV’s total production.
