About the project
Harmony Link is a new submarine interconnection between Lithuania and Poland. It is the largest project of synchronisation of the Baltic States with the Continental European Synchronous Area.
The approximately 330 km total length of 700 MW submarine and onshore high-voltage direct current (HVDC) cable will connect the Žarnoviec substation of Poland with the Darbėnai substation of Lithuania. Construction of the interconnection is expected to be completed in 2025.
It will be the second electricity interconnection between Poland and Lithuania – since 2016, the LitPol Link has been in operation.
