The Swedish government has granted permission for the construction of the Harmony Link sea link between Lithuania and Poland in its exclusive economic zone. The direct current high-voltage cable will stretch about 15 kilometers in Sweden's exclusive economic zone.

A permit for the construction of offshore power transmission cables is required under the provisions of the Continental Shelf Act of the Kingdom of Sweden.

The Harmony Link offshore connection is being developed to import and export electricity to the single European electricity market. The connection, with a capacity of 700 MW and a length of about 330 kilometers, will connect the Darbėnai substation in the Kretinga district and the Žarnovieci substation in the Polish Pomeranian region.

The preparatory work for Harmony Link has been going on since the beginning of 2019. In this project, Litgrid organizes the public procurement of the cable, while the company's partners, the Polish operator PSE, organizes the procurement of the converter stations. Contracts with the winners of the procurement are planned to be signed by April this year.

"The approval of the Swedish government for the construction of Harmony Link is another step forward in the implementation of this important project that will strengthen market integration. Back in 2021, together with the joint project team of the Polish operator PSE, we applied to the Kingdom of Sweden with an application for this permit. It was granted at the very end of last year," said Rokas Masiulis, CEO of Litgrid, the operator of the Lithuanian electricity transmission system.
