Poland and Lithuania have signed a key agreement to advance a new electricity interconnector aimed at strengthening regional energy security amid growing concerns over Russian hybrid threats to critical infrastructure. 

The agreement, signed by Poland’s state-owned electricity transmission operator PSE and its Lithuanian counterpart Litgrid in Vilnius on Thursday, marks a key step toward building Harmony Link, a second electricity connection between the two countries.  

Construction is expected to begin in the second quarter of 2027, with the interconnector scheduled to become operational by the end of 2030. 

“Today, the greatest risk to our security (...) is the risk associated with energy,” Polish Energy Minister Miłosz Motyka, who took part in the signing ceremony, said.  

He warned that incidents linked to hybrid warfare could disrupt electricity systems across Europe, highlighting the importance of stronger connections between neighboring countries. 

For decades, Lithuania, Latvia and Estonia were connected to a Soviet-era electricity network under the BRELL framework, linking their power systems with those of Russia and Belarus.
