In Poland, cable damage was reported in the Baltic Sea

The company "Polish Energy Networks" (PSE) reported a malfunction of the underwater cable connecting the republic with Sweden along the bottom of the Baltic Sea. The statement is published on the official website of the company.

"The Poland-Sweden connection is temporarily disconnected due to a malfunction. The power system works stably and all safety criteria are met," the report says.

According to preliminary data, the failure was not caused by a deliberate action, PSE representatives added. Preparatory work is underway to repair the damaged element.

According to Polskie radio, we are talking about the SwePol line, a DC cable line launched in 2000. The length of the connection exceeds 250 km, of which about 240 km passes under water. The maximum power of the line is up to 600 MW.

In February 2025, a break in the C-Lion1 communication cable between Finland and Germany was recorded off the coast of the Swedish island of Gotland in the Baltic Sea.

In the same month, Rostelecom reported damage to the Baltika cable connecting the Leningrad region with Kaliningrad and passing, among other things, through the economic zones of Finland and Sweden; a similar accident occurred in October 2023. In January 2024, the EstLink 2 power cable between Estonia and Finland failed; the Finnish authorities detained the Eagle S tanker on suspicion of involvement in the damage.

In November 2024, in addition to C-Lion1, the BCS East-West Interlink cable between Lithuania and Sweden was damaged; in this regard, the Chinese cargo ship Yi Peng 3 came under suspicion. At the end of December, the C-Lion1 operator again reported a breakage, and then three more cables were damaged, including the Elisa and CITIC Telecom. In January 2025, the Latvia—Sweden fiber optic cable was damaged.

Against the background of the incidents, NATO launched Operation Baltic Sentry in mid-January 2025 with the participation of frigates, naval aviation and drones to monitor the situation in the Baltic Sea.

The Russian authorities reject accusations of involvement in cable breaks and sabotage in NATO countries. The Washington Post wrote that the intelligence services of the United States and several European countries are inclined to believe that Moscow is really not involved in these incidents, RBC clarifies.
