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

This is physical disconnection from the last remaining element of our reliance on the Russian and Belarusian energy system,” Nausėda said.

After the Baltic decoupling, the energy system in the Russian enclave of Kaliningrad will lose its grid connection to mainland Russia. Kaliningrad has been building up power generation capacity for years and Kremlin spokesperson Dmitry Peskov dismissed all concerns.
