On Thursday, Ukraine raced to restore power throughout the country after Russia launched a new round of missiles at critical infrastructure, temporarily shutting down most of its power plants and leaving the "vast majority" without electricity.Due to Wednesday's assault, which targeted power generation facilities and resulted in a "systemic incident," the national energy company Ukrenergo stated that work was "taking longer than after previous attacks."According to Kyrylo Tymoshenko, an official in President Volodymyr Zelensky's office, on Telegram, electricity had been restored to "all regions" by Thursday afternoon, but individual households were still "gradually being connected to the grid."On Wednesday afternoon, 51 Russian missiles and five attack drones were shot down, according to the Ukrainian military.The Ministry of Energy stated that the attack "led to the temporary de-energization of all nuclear power plants, as well as the majority of thermal and hydroelectric power plants." Among the dead were a teenage girl.It knocked out power to a lot of the country, affecting heating, water supply, and internet access in some places.The head of the state-owned nuclear energy company Energoatom said in a statement that the four nuclear power plants in Ukraine were shut down simultaneously on Wednesday for the first time in 40 years.Petro Kotin stated that it was a preventative measure and that he anticipated a reconnection by Thursday evening.He stated that the three fully operational Ukrainian plants—the occupied Zaporizhzhia plant has not operated since September—would assist in supplying electricity to the national grid.The World Nuclear Association says that nuclear energy is very important to Ukraine.Prior to Russia's full-scale invasion in February, it generated approximately half of its electricity from 15 reactors at four plants.In anticipation of the bitter winter, Russia has focused on destroying Ukraine's energy infrastructure, and a series of strikes have resulted in widespread blackouts across the country.
