Hafslund Eco Selects GE Vernova to Deliver New Rotorpoles in Norway

GE Vernova’s Hydro Power business announced today that it has been selected by Hafslund Eco to deliver new Rotorpoles for the 3x 280 MW / 300 MVA water-cooled generators used by the Aurland 1 hydropower plant in Norway.

The replacement of the Rotorpoles on the three water-cooled generators will help maintain the efficiency of the generators for decades. The services activities will be completed between the summer of 2025 and 2027.

The Rotorpoles are to be assembled in GE Vernova’s Norway Services Workshop in Lier.

To optimize downtime, Hafslund Eco also decided to combine the service of the water-cooled generators with the refurbishment program of the hydropower plant expected within the same timeframe.

Water-cooled generators can offer up to 20-30% higher power output and higher efficiency than conventional air-cooled generators, reducing operating temperatures and ventilation losses. GE Vernova’s Hydro Power business has demonstrated its expertise delivering components for projects in Norway and beyond.

Tormod Kleppa (Director of Projects), Hafslund ECO, said: "We are happy to be working with GE on this project. The Servicing of our Aurland 1 is an important project for us and we are glad to count on GE to deliver the new Rotorpoles while the refurbishment program is undergoing."
