Earlier this week, a Ukrainian drone attack on the Luch substation led to power outage in the city.
"The armed forces of Ukraine struck at the Raduga substation. The transformer has been damaged. Experts are working on fixing the problem," the administration wrote on its Telegram channel.
Another drone attack on Energodar partially damaged the second substation, which supplies the city with electricity, mayor Eduard Senovoz said.
The attack did not lead to any casualties but most of Energodar is left without electricity and water, the mayor added.
