Lithuania’s electricity transmission operator, Litgrid, has unveiled a strategic concept to ramp up cross-border power flows with Poland. The plan aims to enhance the effectiveness of electricity trade, fostering better conditions for Lithuania’s renewable energy development. The plan’s success will also depend on the active collaboration of the industry stakeholders, the company stated.
Since the Baltic synchronisation, the average transmission capacity for electricity trade with Poland is approximately 170 megawatts (MW) for exports and 150 MW for imports.
According to the concept, in 2026, electricity export capacity via the LitPol Link interconnector would reach up to 365 MW, while import capacity would be up to 200 MW. From 2027 onward, those figures jump further—to 500 MW exports and 353 MW imports—reversing pre-sync levels of 350 MW exports and 492 MW imports. Complementing this, Litgrid and Poland’s PSE are advancing the onshore Harmony Link project, planned to go live in 2030. This second interconnector will unlock up to 1,200 MW in bidirectional trade. Stakeholders have until 1 November to submit their feedback, with the full details available on Litgrid’s website.
“Higher trading capacities are primarily related to the opportunities to provide frequency stability ensuring ancillary services, which can be offered by electricity storage facilities connected to the transmission grid,” said Donatas Matelionis, Head of the Power System Operations Department at Litgrid. “In addition, a more active involvement of renewable energy producers in emergency control will also be needed. We have prepared a concept for increasing transmission capacity and announced a public consultation, where we will await questions and suggestions from market participants. By working together, we can achieve the growth of electricity import and export opportunities with Poland.”
This step builds on the Baltic states’ February milestone, when they severed ties with Russia’s IPS/UPS grid and synced with continental Europe’s network. The move empowers closer coordination with 26 nations serving over 400 million consumers, bolstering frequency stability, energy autonomy and regional security.
