In September 2008, the TSOs TenneT in the Netherlands and Energinet.dk in Denmark decided to investigate the possibilities of establishing an interconnection between Denmark and the Netherlands. The purpose is to incorporate more renewable energy into both the Dutch and the Danish power systems and to boost the security of supply. Moreover, the cable will help to intensify competition on the northwest European electricity markets.

A regional business case for Denmark, the Netherlands and Germany is expected to be drawn up in 2014, and this will clarify the socioeconomic benefits for the region, the capacity of the cable, the size of the investment required and when the cable can be expected to be in operation. A final investment decision is planned for in December 2014. Commissioning of the cable connection follows 3-4 years later.
