On February 8 and 9, the planned disconnection of the Baltic energy system from Russia and synchronisation with the European energy system will take place in three stages.

In the first stage, all interconnections will be sequentially disconnected at the Königsberg (Kaliningrad)-Lithuania, Belarus-Lithuania, Russia-Latvia, and Russia-Estonia borders.

In the second stage, the Baltic energy system will temporarily operate in an island mode as a separate synchronous energy system without a synchronous connection to any other energy system. During the island mode frequency and voltage tests will be carried out. The aim of the tests is to assess the procedural and technical measures of the Baltic States for maintaining frequency and their ability to cope independently.

In the third stage, the Baltic energy system will be prepared for synchronisation, and a synchronous connection will be established with Poland's energy system via the LitPol Link transmission line.

The disconnection process from the BRELL network will take place on Saturday, February 8, from 6:00 AM. The connection to the European energy system is scheduled for Sunday, February 9, around 2:00 PM. Times may vary depending on circumstances.
