Lithuania said on Saturday it had disconnected its electricity system from Russia’s power grid, part of a plan that the three Baltic states say will integrate them more closely with the European Union and boost security, Report informs via Reuters.

Latvia and Estonia are expected to follow suit by 07:00 GMT on Saturday and, subject to last-minute tests, the three countries will synchronize with the EU’s grid on Sunday after operating on their own in the meantime.

“We have disconnected,” a spokesperson for Lithuanian grid operator Litgrid said.

Plans for the Baltics to decouple from the grid of their former Soviet imperial overlord, debated for decades, gained momentum following Moscow’s annexation of Crimea in 2014.
