Belgium and Denmark have signed a Memorandum of Understanding to build a 600 km offshore power transmission project between the two countries. A submarine cable, which is expected to have a capacity of 1.4 GW, will link the Danish offshore wind parks to the Belgian coast by 2030. The project is likely to cost up to €600m. The Belgian and Danish power transmission system operators Elia and Energinet will start jointly study the technical side of the project and will launch a feasibility study.
In October 2020, the German power transmission system operator 50Hertz and its Danish counterpart Energinet completed the 400 MW Kriegers Flak - Combined Grid Solution (CGS) transmission project that will enable Denmark and Germany to exchange power via offshore wind parks in the Baltic Sea. The project, which required a €300m investment, connects the Baltic 1, Baltic 2 wind parks (which total 336 MW) and, from 2021 with Kriegers Flak (600 MW), with the two countries. In addition, the two companies signed a Letter of Intent (LoI) in January 2021 to pursue collaboration in the "Bornholm Energy Island" project to connect Denmark and Germany to an offshore hub with around 2,000 MW of wind power capacity that is planned on the Baltic Sea island of Bornholm (Denmark).
