==Construction== It is estimated to cost €1.5–2 billion, which was financed in 2015 when Statnett decided to realize the project. The interconnector was installed between a new substation at Ertsmyra (near Tonstad) in Norway and Wilster substation in Schleswig-Holstein in Germany. The connection was expected to be completed in 2020. When testing in September 2020, it accidentally imported the full 1,400 MW into Norway for almost a minute, causing cascading grid effects such as a 0.5 Hz frequency change across the Nordic synchronous area. The opening ceremony took place on 27 May 2021.
