Synchronisation of the Baltic States' electricity grid with the continental European system

On 28 June 2018, Commission President Juncker together with the Heads of State and Government of Poland, Lithuania, Latvia and Estonia signed a Political Roadmap for the synchronisation of the Baltic States' electricity grid with the continental European system.

In line with this Political roadmap, the High-Level Group on synchronisation has met today. The High Level Group welcomed the results of the latest dynamic and frequency stability study presented by the European Network of Transmission System Operators for Electricity (ENTSO-E).

The study results show that the synchronisation option chosen by the political leaders in June – consisting of the existing double-circuit alternating current (AC) line between Poland and Lithuania (LitPol Link) complemented by the construction of a new offshore high voltage direct current (HVDC) link between Poland and Lithuania – is technically feasible at reasonable cost. Importantly, the High Level Group agreed with the analysis that the chosen option will guarantee the safe operation of the Baltic States' electricity grid at the same level as in the continental European electricity networks, provided that the technical measures identified in the study are implemented. 

After verification that all technical, financial and time-related preconditions are complied with, the High-Level Group has concluded by giving the green light to formally launch the synchronisation process and to meet during the first quarter of 2019 to endorse the Connection Agreement and the catalogue of measures finalised by the TSOs and ENTSO-E.

The Commission continues to extend its full support for the project and the High Level Group will continue to closely monitor the process.
