Ukraine is banning the import of electricity from Belarus and Russia for four months, until Oct. 1.

“We remember our experience last winter,” Valeriy Tarasiuk, chairman of the National Energy and Utilities Regulatory Commission of Ukraine yesterday told a public meeting. After power stations ran short of coal, the government imported electricity, first from Belarus in January, then from Russia in February. The move to stop electricity imports started before Belarus forced down the Ryanair passenger jet on Sunday. President Zelensky seeks to make Energoatom, Ukraine’s state-owned nuclear power producer, profitable. Responsible for producing half of Ukraine’s electricity, Energoatom lost $177 million last year.
