Estonia, Latvia and Lithuania said on Sunday they had successfully synchronized their electricity systems to the European continental power grid, one day after severing decades-old energy ties to Russia and Belarus.
Planned for many years, the complex switch away from the grid of their former Soviet imperial overlord is designed to integrate the three Baltic nations more closely with the European Union and to boost the region's energy security.
"We did it!," Latvian President Edgars Rinkevics said in a post on social media X, Reuters reported.
After disconnecting on Saturday from the IPS/UPS network, established by the Soviet Union in the 1950s and now run by Russia, the Baltic nations cut cross-border high-voltage transmission lines in eastern Latvia, some 100 metres from the Russian border, handing out pieces of chopped wire to enthusiastic bystanders as keepsakes.
EU foreign policy chief Kaja Kallas, herself an Estonian, earlier this week called the switch "a victory for freedom and European unity".
The Baltic Sea region is on high alert after power cable, telecom links and gas pipeline outages between the Baltics and Sweden or Finland. All were believed to have been caused by ships dragging anchors along the seabed following Russia's invasion of Ukraine. Russia has denied any involvement.
Poland and the Baltics deployed navy assets, elite police units and helicopters after an undersea power link from Finland to Estonia was damaged in December, while Lithuania's military began drills to protect the overland connection to Poland.
Analysts say more damage to links could push power prices in the Baltics to levels not seen since the invasion of Ukraine, when energy prices soared.
The IPS/UPS grid was the final remaining link to Russia for the three countries, which re-emerged as independent nations in the early 1990s at the fall of the Soviet Union, and joined the European Union and NATO in 2004.
The three staunch supporters of Kyiv stopped purchases of power from Russia following Moscow's invasion of Ukraine in 2022, but have relied on the Russian grid to control frequencies and stabilise networks to avoid outages.
