The Finnish authorities are investigating the sudden power outage at the Estlink 2 interconnector between Finland and Estonia that occurred yesterday, December 25, the country’s Prime Minister Petteri Orpo said.

Finland’s transmission system operator (TSO) Fingrid reported to the authorities the possible failure of the electricity cable on Wednesday afternoon, prompting an immediate investigation into the chain of events of the incidents as well as whether a foreign cargo ship is involved in the damage.
