On 12 February 2026, the SwePol undersea power cable linking Poland and Sweden in the Baltic Sea unexpectedly stopped operating, with repairs underway and no evidence yet of deliberate sabotage.
A critical 250 km HVDC power cable named SwePol, running under the Baltic Sea between Poland and Sweden, unexpectedly failed on Wednesday evening, 12 February 2026, cutting off power flow as market data showed energy transfer falling to zero just before 8 p.m. The Polish grid operator PSE confirmed stable system operation and safety compliance despite the failure. Repair efforts commenced immediately with restoration expected by midnight Friday. The cable connects terminals near Slupsk in north-central Poland and Sweden's Stärnö peninsula and can carry up to 600 MW of power. This incident occurs in a context of recent Baltic Sea hybrid warfare attacks targeting undersea infrastructure, including deliberate damage to cables between Finland and Estonia and the Nord Stream pipeline explosions. Although currently there is no indication this failure was intentional, regional tensions and the history of sabotage highlight the strategic vulnerability of such infrastructure in the area.
Confidence: High
The article reports a technical failure of an undersea power cable with no evidence or suggestion of deliberate sabotage or hostile action at this point. The narrative mentions hybrid warfare context but does not attribute this incident as an aggressor attack or defense preparation.
