Russian strikes have in recent weeks affected 80% of Ukrainian thermal power plants and half of hydroelectric power plants. "This is the largest attack on the Ukrainian energy sector," the minister reported.

The level of damage caused has not been confirmed, the ministry's press service told AFP. Before the Russian invasion launched in February 2022, electricity production in Ukraine was relatively balanced between thermal and nuclear power plants, with a lower percentage of hydropower. The Ukrainian nuclear power plant in Zaporizhia (south), located in the region of the same name and the largest in Europe, has been occupied by Russia since the start of the war.
