The electricity supply has been restored in Crimea after the peninsula suffered a blackout following an incident at a power station, Russia’s state-controlled power grid company Rosseti said on Wednesday. The problem was caused by an automatic shutdown after a surge of electricity at the ‘Taman’ switching substation in southern Russia, according to the ministry. The blackout was registered in parts of Simferopol and Sevastopol, and there were also problems with cellular communications. Local officials confirmed earlier reports that the surge at the ‘Taman’ substation in Krasnodar Region had caused the blackout.
