The suspected fault in EstLink 2 is located on the seabed of the Gulf of Finland 

Measurements conducted on Thursday by system operators Elering and Fingrid indicate that the fault in the EstLink 2 electricity connection between Estonia and Finland lies in the underwater section of the connection on the Finnish side. 

This assessment is based on cable measurements. The suspected fault has not yet been physically identified. 

Fingrid updated the urgent market message ( Nord Pool - UMM Platform ) at 12:34 PM today, stating that based on previous experience, the repair of the fault is planned to be completed by August 1, 2025. If the repair timeline is clarified in the future, the market message will be updated accordingly. 

The EstLink 2 fault does not hinder the planned desynchronisation of the Baltic states from the Russia-controlled frequency area and synchronization with the Continental European electricity grid, scheduled for early February 2025. The Baltic states have sufficient controllable capacity and interconnections to carry out the synchronization with the Continental European frequency area even without the EstLink 2 connection. 

The fault in EstLink 2 may affect electricity prices on the exchange in Estonia and other Baltic states. If renewable energy production in the Baltic states is high, the Estonia-Finland connection has little impact on prices. Price effects are more likely in situations where renewable electricity production is low. In such cases, prices depend on gas power plants in the Baltic states and oil shale power plants in Estonia. Based on experience from the first half of this year, it can be expected that prices in the Baltic states will be somewhat higher than in the Nordic countries. However, during peak demand periods, prices may be lower compared to the Nordic countries, as deficits have also arisen in Finland during peak periods, causing electricity to flow from the Baltic states to Finland.
