Litgrid and PSE make investment decisions for Harmony Link

Litgrid and PSE have approved the final investment decisions on the implementation phase of the Harmony Link interconnector, a submarine power cable line between Poland and Lithuania.

In line with the signed cooperation agreements, the decisions enable the start of tender procedures for the selection of contractors for the high voltage direct current (HVDC) cable and HVDC converter stations.

Under the agreement signed in May 2020, the transmission system operators of Lithuania and Poland divided the work set to be carried out by each party.

Litgrid will be responsible for the installation of the required HVDC cable while PSE will be responsible for HVDC converter stations in Lithuania and Poland.

Both companies, separately for their respective part of works, will select contractors, sign contracts and implement them.

“Following the adoption of the final investment decisions in both countries, Litgrid and PSE will be enabled to continue carrying out the works scheduled in the pipeline”, says Rokas Masiulis, CEO of Litgrid.

“Litgrid and PSE are currently carrying out the territorial planning and environmental impact assessment processes required for the Harmony Link project, preparing tender documents for the construction of cable and converter stations, exploring the seabed for cable construction, and Litgrid has acquired a plot for converter station construction in Darbėnai”.

Earlier this year, the seabed survey started in the Baltic Sea as part of the construction of Harmony Link.

Harmony Link will comprise a submarine cable power line of approximately 330 kilometres, of which approximately 290 kilometre will be offshore. It will connect the Żarnowiec substation in Poland with the future Darbėnai substation in Lithuania.

The interconnector will be based on HVDC technology and will provide transmission capacity of 700 MW. It is expected to be completed in 2025.
