AFRY has entered into an agreement with Hafslund Kraft AS in Norway to study the possibility of increased flexibility in the Aurland 3 Pumped Storage Power Plant.

Aurland 3 is one of the largest pumped storage power plants in Norway with two fixed speed reversible turbines, each with a capacity of 135 MW.

The scope of the assignment is to explore possibilities to significantly increase the number of starts and stops per year and increase the flexibility in operating range of the plant. Utilizing hydro expertise from Norway, Austria and Switzerland, AFRY will investigate possible system concepts and prepare a basis for decision-making regarding the system technology going forward.

“The Aurland 3 project is an important step in strengthening our footprint in the Nordic market for pumped storage hydropower. AFRY has long experience from similar projects in a number of countries and we are happy to support Hafslund in this technically challenging project,” says Marcus Bergman, Sales Manager Hydro Nordics at AFRY.
