Investments cleared for 700-MW interconnector between Poland, Lithuania

Polish transmission system operator (TSO) PSE SA and Lithuania’s Litgrid have approved investments in a 700-MW interconnector project between Poland and Lithuania.

The Harmony Link will be a 330-km (205.1-mile) undersea cabling system that will connect Zarnowiec, Poland, and Lithuania’s Darbenai and allow the synchronisation of the Baltic states’ power systems with the synchronous area of continental Europe. It will also enable the integration of further renewable energy capacity in the Baltic countries when it comes online in 2025.

PSE and Litgrid have taken final investment decisions on the implementation phase of the EUR-700-million (USD 854.7m) project, PSE said on Monday. The next step will be to initiate tender procedures for finding contractors for the high voltage direct current (HVDC) cable and converter stations. Territorial planning and environmental impact assessment are currently ongoing on each side.

The scheme will be funded with EUR 500 million in grant financing from the European Union (EU). As agreed last year, Litgrid will install the HVDC cable, while PSE will be in charge of the converter stations in both countries.

The interconnector will be the second one between Poland and Lithuania. The first one, the LitPol Link, is an overhead power line that has been operating since 2016.
