The governments of Estonia and Finland said in separate statements that they will convene for emergency meetings on Thursday, as Estonian and Finnish investigators try to find out who is behind the damage to an electrical cable in the Baltic Sea connecting the two countries.
Repairs to the 170-kilometer Estlink 2 interconnection cable will take months and disruption of supply through this line could cause problems with energy supply during the winter, Finnish operator Fingrid said in a statement.
Police and media report that Finnish authorities have detained a Russian-bound ship named 'Eagle S', while investigations are underway into whether it damaged a power cable in the Baltic Sea and several data cables.
The Estlink-2 line stopped working shortly after noon on Wednesday. Officials expressed concern that this could be another attack similar to incidents that damaged two data cables in November and the explosion that damaged the Nord Stream gas pipeline in September 2022.
"Although it is a holiday season, many people in Estonia and Finland have been working over the past two days to identify the problem of the Estlink-2 line outage," Estonian Prime Minister Kristen Michal told the X network, adding that "my government will hold an extraordinary meeting this afternoon. We are in close contact with our Baltic-Northern colleagues."
Two data transfer cables, one running between Finland and Germany and another running between Lithuania and Sweden, were damaged in November.
The German Defense Minister said officials should assume the incident was "sabotage," but he did not provide any evidence or say who might be responsible.
His comment came during a discussion on hybrid warfare threats from Russia.
The Nord Stream pipelines, which once transported natural gas from Russia to Germany, were damaged by an underwater explosion in September 2022. Authorities have described the incident as sabotage and have launched a criminal investigation.
The 'Estlink-2' line was out of service for most of the year, due to some repairs to damage that may have been caused by the complex positioning of the line, ERR television said.
Estonian power grid operator Elerin said it has sufficient reserve capacity to meet the country's needs, public broadcaster ERR reported on its website.
