en.Wedoany.com Reported - Sweden's and Denmark's transmission system operators, Svenska Kraftnät and Energinet, are proceeding with the replacement of an aging submarine cable system connecting the two countries. The System 2, consisting of three 400 kV submarine cables, has been in operation for nearly 40 years and is approaching the end of its technical lifespan, and will be replaced by three new cables.

The two operators jointly own and operate four Øresund connection links, connecting Zealand with southern Sweden via two 400 kV and two 132 kV connections. The first 400 kV system (owned by Svenska Kraftnät) was already renewed in 2020. The System 2 being replaced this time is owned by Energinet, and the route for the new cables largely follows the old route near the Swedish coast, while deviating near the Danish coast.

This spring, new onshore cables between the coasts on both the Danish and Swedish sides and nearby high-voltage substations have been laid.

Regarding the submarine cable section, coastal drilling work commenced in early May east of Hornbæk on the Danish side and at the site on the Swedish side, and will continue until June.

A series of preparatory works will be carried out at sea in July, including surveys and work area preparation. Some existing cables will be removed, and the new cables will be laid and pulled ashore in stages from August to September — first on the Swedish side, then the Danish side. After final testing in October, the new cable system will be put into operation. The remaining old submarine cables will be removed in November and December.
