A business case for reinvesting the northern Øresund cable, owned by Energinet and forming part of the Danish–Swedish Øresund interconnection, was approved in summer 2022, putting the reinvestment project into the planning phase with an expected operation date in 2027.
In 2017, the Oresund 132 kV interconnection between Denmark and Sweden was successfully completed by Hellenic Cables, bringing into full operation a high‑voltage AC link using submarine and land cables that seamlessly connected the two countries’ grids across the Øresund strait.
By 2017, Hellenic Cables, under contract to Energinet, had completed the design, manufacturing, supply and supervised installation of the high-voltage submarine and associated land cables for the Øresund 132 kV interconnection linking Denmark and Sweden, replacing ageing 132 kV cables across the Øresund strait and forming part of Energinet’s Øresund 132 kV renewal project planned to enter operation shortly thereafter.
On 18 December 2015, an international competitive tender was launched inviting bids for the transportation, installation and protection of new 132 kV three-core submarine cables in the Øresund Strait between Denmark and Sweden, initiating the procurement process for works on the Øresund 132 kV interconnector replacement project.
In Energinet’s System Plan 2013, published in March 2014, the TSO reported that it was examining, together with neighbouring TSOs, a new connection across the Øresund from Zealand to Sweden to replace the existing North Zealand 132 kV connection, marking the early development phase of the Oresund 132 kV reinvestment project.
Energinet planned a brief outage period during the commissioning of the replacement 132 kV cables across Øresund to Sweden, with the new cables being installed in parallel with the existing 1950s cables and expected to become operational in early 2018.
