Finland’s prime minister says the country is looking into the underwater power transmission interruption to Estonia

Petteri Orpo, the prime minister of Finland, announced on Wednesday that his nation’s officials were looking into an underwater power cable loss on a route that connects Finland and Estonia.

In a statement posted on the Nordpool regulatory website, operator Fingrid stated that an unscheduled outage of the Estlink 2 interconnector at 10:26 GMT had reduced its installed capacity of 1,016 MW to 358 MW.

Orpo said in a post on X, “Even at Christmas the authorities are on standby to investigate the matter,”

He said that Finland’s electrical supply was unaffected by the disruption.

Although subsea cables are also susceptible to technical issues and outages brought on by accidents, authorities in the area have been on high alert for possible acts of sabotage after a series of power cable, gas pipeline, and telecom connection disruptions in the Baltic Sea in recent years.

“An investigation into the incident has been initiated,” Arto Pahki, the manager of the Fingrid control room, said in a statement.

According to Fingrid, the power was moving at a pace of 658 MW from Finland to Estonia at the time of the interruption.
