The head of the Ukrainian energy holding DTEK Maxim Timchenko called the energy situation in the country catastrophic.
Kyiv Mayor Vitali Klitschko has several times in January urged Kiev residents to go out of town to alternative sources of power and heat amid problems with electricity and heating in the city.
"We are close to a humanitarian catastrophe," the Reuters news agency quotes Timchenko as saying.
According to him, people receive electricity for three to four hours, after which it disappears again for 10-15 hours.
"We have apartment buildings that have been without heating for weeks," he added.
Earlier, the director of the Ukrainian Energy Research Center, Alexander Kharchenko, said that Kiev had actually lost its power generating capacity and was supplied with electricity only from the outside.
