Christmas Day Blackout Hits Key Estonia-Finland Power Link
A vital subsea cable, Estlink 2, snapped offline on Christmas Day at 12:26pm, cutting electricity flow between Finland and Estonia. Finnish grid operator Fingrid confirmed the sudden outage stopped a hefty 658 megawatts from crossing the Gulf of Finland.
Probe Launched as Sabotage Not Ruled Out
Fingrid’s Operations Manager Arto Pahkin said sabotage remains a possibility as teams frantically inspect the underground cable and substations on both ends. “It will take several hours to determine the cause,” Pahkin said. “Our teams are combing the cable route and infrastructure on each side of the Gulf.”
Meanwhile, the smaller Estlink 1 line, with 350 megawatts capacity, stays online and running.
No Power Crisis but Vigilance High
Finnish Prime Minister Petteri Orpo took to social media to calm nerves. “Finland’s electricity supply is unaffected,” he reassured followers on X. “Authorities remain alert even through Christmas and are investigating the fault.”
Industry insiders agree the impact on prices should be minimal. Jukka Relander from Finnish Energy said, “Estlink 2 mainly exports power from Finland, so its outage won’t drive up electricity prices significantly.”
Estlink 2: The Energy Lifeline at Risk
With a 650-megawatt transmission capacity, Estlink 2 is a critical artery for cross-border electricity between Finland and Estonia and a key cog in Europe’s energy network. Pahkin stressed the need to avoid interruptions to keep the system stable.
The outage follows a lengthy closure for maintenance earlier this year, underscoring just how vulnerable the cable is. Officials from both nations are working round the clock and promise updates as the inquiry unfolds.
