The hydroelectric power station at a reservoir on the Dnipro river near Zaporizhzhya, which was damaged in a Russian missile attack, is in "critical condition" according to the authorities on Saturday.
Specialists must assess how safe the dam is, said the military governor of the southern Zaporizhzhya region, Ivan Fedorov, on Ukrainian television. "At the moment, traffic from the left bank to the right bank is completely blocked, so traffic is restricted for local residents."
The power plant has been attacked several times by Russian forces over the past few months. A fire broke out during a massive missile attack at the end of March. The power plant sustained serious damage and had to be shut down for a while.
Another missile attack hit the plant during the night and the dam was temporarily closed to traffic.
Russia began its full-scale war on Ukraine in 2022 and Moscow repeatedly attacks civilian targets such as cities and energy supply facilities in particular.
Ukraine has lost more than 8,000 megawatts of power plant capacity since the start of the war, leading to the imposition of rationing and higher electricity prices.
