The cost-reduction calculation, which comes out of the company's Force (For Reduced Cost of Energy) project into the potential efficiencies of integrated design, relaxation of frequency constraints, enhanced control systems and slimline blades, suggests over €1bn ($1.35bn) in net present value terms could be saved in the next ten years.

“The cost savings identified by the Force team could be exploited by industry right now," states DNV GL executive vice president for renewables RV Ahilan.
