The electricity systems of the Baltic States have been successfully disconnected from the Russia-controlled IPS/UPS system and are now operating independently in island mode. Elering, Augstsprieguma tīkls (AST), and Litgrid, the electricity transmission system operators of Estonia, Latvia, and Lithuania are now conducting an isolated operation test before synchronising to the Continental European grid.

The power systems of the Baltic States successfully disconnected from IPS/UPS system at 09:09 AM. The separation of the Baltic electricity systems from IPS/UPS had no impact on consumers, the systems are stable and secure.

The isolated operation test is a crucial step in the preparation for synchronisation of the Baltic electricity systems with the Continental European Synchronous Area (CESA). During this period, the Baltic Power System autonomously controls the frequency in the power system. The power supply status can be monitored on a digital map: https://www.ast.lv/en/content/power-system-state.

The synchronisation process with Continental Europe is scheduled to be completed on February 9 around 2 PM. The Baltic system operators have been preparing for this transition for more than 15 years by investing in the development of transmission infrastructure and equipment necessary for the safe operation of their electricity systems.

Once synchronized, Lithuania, Latvia, and Estonia will join the world's largest synchronous grid, serving over 400 million consumers across 26 countries. Until now, the Baltic States were part of the Russia-controlled IPS/UPS synchronous area.

Synchronisation with CESA will allow for independent, stable and reliable frequency control of the Baltic States electricity grids and will increase the energy security in the region.

Process of synchronisation of the power systems of the three Baltic States is supported by European Union and ENTSO-E (association of European transmission system operators). It included co-funding infrastructure investments as well as technical and operational support, which facilitated the process. The synchronisation project is implemented with significant co-financing of the European Union.
