Estonia, Latvia, and Lithuania have successfully synchronized their electricity grids with the Continental Europe Synchronous Area (CESA) on 09 February 2025 at 14:05 EET, marking a historic milestone in their journey towards strengthened energy system resilience and integration with the Continental Europe electricity grid.

This synchronization enables the Baltic States to manage their electricity grids in close cooperation with all other Continental European countries, with stable and reliable frequency control, significantly enhancing regional energy security. Previously relying on the Russian and Belarussian systems for frequency management, the Baltic states have now joined the synchronous grid of Continental Europe, serving over 400 million customers. All electricity interconnections with Russia and Belarus have been permanently disconnected.
