Denmark and Germany are major advocates in decarbonization, and have been vigorously developing offshore wind power, where the offshore wind farms of both countries not only serve as the source of carbonless renewable power, but could also become the reciprocating bridge for the power grids of the two countries. Danish grid distribution operator Energinet and German transmission system operator Amprion commented that the two will look into the feasibility of hybrid offshore power interconnectors, which refer to connecting hybrid wind farms to power grids, as well as connection between the grids of the two countries.
Energinet commented that the establishment of an offshore grid connection between Germany and Denmark is an essential step in exploring the enormous wind energy resources of the North Sea and connecting it to continental Europe, where a hybrid power interconnector would portray the role of distributing electricity from offshore wind farms to Germany and Denmark, as well as connect the grids of the two countries.
The hybrid power interconnector mentioned from the plan directly connects Denmark to the North Sea Energy Island, and connects Germany to the offshore wind farm grid that will directly distribute power to Germany’s grid when Denmark is left with excessive offshore wind power, before arriving at Germany’s core regions of power consumption. The hybrid power interconnector also offers various options for grid operators of the two countries in order to maintain frequency and voltage for their respective grids 24/7.
This project, once completed, will considerably benefit the power dispatch between Denmark and Germany. With that being said, a fundamental issue is that both countries would often experience excessive power generation from their respective wind farms during blustery at the North Sea in the past, where the insufficient distribution capacity from Northern Germany to Southern Germany in the past would always force the former to give up on wind power during peak power generation of offshore wind power, which will make distribution of excessive power in Denmark to Germany quite meaningless, unless Germany comes up with an aggressive construction scheme that will shatter the distribution bottleneck between Northern and Southern regions of the country.
