Harmony Link

Harmony Link is a planned electricity link between Lithuania and Poland. The purpose of the cable is to finish the transition of the Baltic states from IPS/UPS to the synchronous grid of Continental Europe.^[2]

The total investment planned for the Harmony Link project is around €680 million, of which €493 million will come from the Connecting Europe Facility.^[3]

On 21 December 2018, Lithuanian electricity grid operator Litgrid and Polish electricity grid operator PSE signed agreement in order to start planning the cable. Project was given an official name Harmony Link.^[4] In June 2023 the construction works started at the Darbėnai transmission station.^[5]

Harmony Link was originally planned to connect the Zarnowiec substation in the Pomeranian region of Poland with the Darbėnai substation in the Kretinga region of Lithuania. The key component of the interconnector was a 700 MW High Voltage Direct Current (HVDC) cable. The power link was to be about 330 km long, of which about 290 km will be the offshore part.^[6]

In late 2023, both countries agreed to change the project and build the link on the land along the Rail Baltica railway infrastructure, instead of the previously planned submarine power cable.^[7]
