signed agreement in order to start planning the cable. Project given official name Harmony Link.
Construction works expected to start in 2023 and finish in 2025.
About the project
Harmony Link will connect the Zarnowiec substation in the Pomeranian region of Poland with the Darbenai substation in the Kretinga region of Lithuania. The key component of the interconnector is a 700 MW High Voltage Direct Current (HVDC) cable. The power link will be about 330 km long, of which about 290 km will be the offshore part.
Construction of the interconnector is expected to be completed in 2025.
Financing
The total investment planned for the Harmony Link project is around €680 million, of which €493 million will come from the Connecting Europe Facility.
