The automatic-control failure at a substation, which left consumers on the right bank in northern Kyiv and nearby areas of the Kyiv region without electricity at midnight, may have been caused by an outside interference, Vsevolod Kovalchuk, head of national power company Ukrenergo, said.

"Our specialists promptly switched the equipment into manual mode and 30 minutes later began restoring the supply. The supply was restored in full within an hour and 15 minutes," Kovalchuk wrote on his Facebook page on Sunday afternoon.

The company is investigating the incident and a commission is already working, he said.

"So far the main theory is an outside interference through data-transmission networks. Our cyber security specialists promised to submit a report very soon," Kovalchuk said.
