Old turbines at the Vemork hydropower plant.
Hydro is going to invest NOK 850 million (~ EUR 102) into upgrading one of the oldest hydropower systems in Norway – the Rjukan hydropower system in Telemark, southeast Norway.
The Rjukan hydropower system is made up of five power plants – Frøystul, Vemork, Såheim, Moflåt and Mæl, which combined produce about 3 TWh of electrical energy annually. This represents about 30% of Hydro's total annual energy production from hydro energy sources.
