Baltic power systems preparing for isolated operation test

The power systems of the three Baltic countries are preparing for the significant step towards synchronisation. For a short period of time they will be disconnected from the energy systems of neighbouring countries and will become an independent energy system for the time of the test. A study on preparation for isolated operation test started in January.

The test of isolated operation is one of the main steps in preparation for synchronisation. When the test is carried out the Baltic countries will restrict their connections with neighbouring countries – Russia and Belarus. To meet power demand, Lithuania, Latvia and Estonia will use only domestic power generation sources and HVDC power interconnections with Nordic countries. The three Baltic countries will independently maintain the balance and frequency of power.
