NordBalt energy link with Lithuania halted due to an accident in Sweden — RMF24

The NordBalt subsea power interconnection between Lithuania and Sweden ceased operating due to an accident at a transmission station in Sweden. The high-voltage line was disconnected, and the Lithuanian power grid operator activated reserve capacity. As RMF24 reports, no disruptions to electricity supplies for consumers were recorded.

The anchor incident in 2024

In November 2024, the NordBalt cable may have been damaged by an anchor, as confirmed by the Swedish operator Svenska Kraftnät. Earlier, Sweden's minister for civil defence reported traces discovered on this interconnection.

Svenska Kraftnät then stated that the cable was ultimately not damaged and that the discovered traces did not lead to restrictions or a halt in electricity supplies.
