Vilnius:Poland and Lithuania have signed an agreement to develop a new electricity interconnector, aiming to enhance Baltic energy security amid concerns over potential hybrid threats to critical infrastructure.
According to Anadolu Agency, the agreement was signed by Poland's electricity transmission operator PSE and its Lithuanian counterpart Litgrid in Vilnius. The agreement outlines the responsibilities for the cross-border connection of Harmony Link, which will be the second electricity link between the two countries.
Construction of the Harmony Link is set to begin in the second quarter of 2027, with plans for the link to become operational by the end of 2030. This timeline was provided by Polish broadcaster TVP World.
Polish Energy Minister Milosz Motyka, present at the signing ceremony, emphasized the strategic nature of the investment. He highlighted the potential disruptions to electricity systems across Europe due to hybrid warfare, stating that the agreement is a crucial step in fortifying the region's energy system. Motyka stressed the importance of regional cooperation to prepare for scenarios including system failures and extreme weather events.
Lithuanian Prime Minister Mindaugas Sinkevicius remarked that the project would not only strengthen regional security but also support Lithuania's goal of becoming an electricity exporter. He described Harmony Link as a significant milestone in building a more secure, resilient, and reliable energy system.
Additionally, Motyka and Lithuanian Energy Minister Lukas Savickas signed a joint statement focusing on the security of energy infrastructure and mutual assistance.
The Harmony Link will complement the existing LitPol Link, which has been operational since 2015, and could increase the electricity exchange capacity between Poland and Lithuania to 1,200 megawatts. This development follows the disconnection of Lithuania, Latvia, and Estonia from the Russian-controlled electricity network in February 2025, as they synchronized their grids with continental Europe through Poland.
