About the project
Harmony Link is a new submarine interconnection between the Lithuanian and Polish electricity systems, which will ensure commercial electricity trading after the Baltic States’ synchronisation with the continental European grid.
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 the 1st quarter of 2028.
