) in Norway and Wilster substation in Schleswig-Holstein in Germany. The connection was expected to be completed in 2020; the opening ceremony took place on 27 May 2021. 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. In November 2021, amid high demand for electricity in Europe, the increased exports from Norway to continental Europe caused conflict with the grid operator of Sweden, which cut export capacity in half, causing the Norwegian operator to do the same for exports to Sweden (on which Denmark and Finland also rely).
