The Baltic states on Saturday began cutting ties with Russia's power grid in order to integrate with Europe's system, a years-long process that gained urgency with Moscow's invasion of Ukraine. The Baltics have long prepared to integrate with the European grid but faced technological and financial issues.

The Baltic states of Lithuania, Latvia and Estonia are bracing themselves for possible retaliation as they decouple from Russia's power grid this weekend.

Disconnecting from the Soviet-era grid faced an intimidation campaign — but it’s Moscow that could be left in a precarious position.
