Two hydropower plants in Ukraine were severely damaged and were no longer in operation after Russian bombardments earlier this week, the state energy company Ukrhydroenergo said Thursday. "As of today all hydro generation has suffered devastating damage," it said in a statement on the Telegram messaging app, adding that significant financial resources and efforts would be required to repair the damage and restore the plants' operations. Ukraine plans to double electricity imports Thursday after the powerful Russian attack on Ukraine's energy system, the energy ministry said.
