Underwater electric cable between Poland and Sweden damaged in the Baltic Sea

The incident occurred on the night of February 13

The underwater electric cable SwePol, connecting Poland and Sweden across the Baltic Sea, has malfunctioned. This was reported by the state company Polskie Sieci Elektroenergetyczne (PSE, "Polish Power Grid").

According to the energy exchange Nord Pool, the cable damage occurred on the night of Friday, February 13. Power supply between the countries was temporarily interrupted as a result of the incident.

Characteristics of the damaged cable

The SwePol direct current cable line was commissioned in 2000 and has the following parameters:

• Length: over 250 km
• Capacity: up to 600 MW

The situation is under control

According to PSE, the energy systems of both countries continue to operate stably, and all safety criteria are met. "So far, everything indicates that the outage was not caused by intentional actions," the press service clarified.

The company confirmed that preparations for the repair of the damaged component are underway. The work was planned to be carried out during the day, but for unknown reasons, it was postponed.

Context of events in the region

This incident occurs against the backdrop of previous damages to underwater infrastructure in the Baltic Sea. At the end of August 2025, a Finnish prosecutor demanded a sentence of two and a half years in prison for the captain of the tanker Eagle S and two of his assistants for damaging the underwater cable EstLink 2, which connects Estonia and Finland. According to the investigation, the crew of the vessel intentionally did not raise the anchor to disrupt communication and power supply between the countries.
