Ukraine's largest private energy company is ready for another winter and Russian attacks, but its power plants need more missile defense systems to operate safely, Chief Executive Officer Maxim Timchenko told Reuters. Since Russia's February 2022 invasion, Europe, including members of the Soviet Union and the ex-Communist bloc, have supplied hundreds of transformers, miles of cables and thousands of diesel generators needed to light and heat the country in winter, when temperatures fall well below freezing. But the experience of the past 12 months has prompted Ukraine to seek more air defense systems to protect its critical infrastructure.
