Kiev had already been on scheduled blackouts where groups of consumers received for example four hours of electricity to then be cutoff for eight hours. That scheduling has ended. The blackout has become permanent.

Over several weeks Russian attacks had isolated the electricity supply in Kiev from other parts of the country. It then attacked generating stations within the city. There is now less than 10% of electricity supply available than the city would normally use. Public lighting has been shut down as much as possible. Factories have closed down. Schools and Universities are on prolonged holidays. Many shops have closed as running their private generators is costing more money than they can make while open.

The electricity generation stations were also supplying hot water for long-distance heating. Several hundred of Soviet era high-rises in Kiev, each of them with hundreds of apartments, have neither heat nor power. The temperature in Ukraine has been below zero degree C for several days. Many of the buildings had not drained their water systems. The radiators and water supply lines have frozen and burst open. Those high rises are now uninhabitable. Experts estimate that up to nine month repair time, and a lot of money, will be needed to fix each of them. There are about 150,000 people affected by this.

Kiev is not the only city in trouble. Odessa is likewise shut down. People are protesting in the streets. Dnipro has similar problems. Today an attack hit Kharkiv and disable one of the last combined heat and electricity station within the city. Sumy and Zaparochia also reported blackouts.

Currently a wave of arctic air is flowing into Ukraine with night temperatures expected to go down to minus 30° centigrade.

The government of Ukraine says that it is expecting a new Russian wave of attacks. This, it says, will likely take out transformer station that make up Ukraine's long distance 750 kilovolt electricity network which is fed by nuclear power stations. The stations are not endangered but they would have to lower their output or shut down as there will be no-one connected to them to receive the electricity they generate.

Large electric energy systems are very complex. To restart a system once it broke down requires a lot of coordination and planning. Any mistake will immediately lead to new breakdowns and damaged equipment. The systems in Kiev are now in a state where it could take weeks without new Russian attacks to get the it up and running again.

Ukraine had been warned that any attack on Russian infrastructure would be responded to in kind. But it continued to attack Russian cities which led to deaths and serious problems in Belgograd and elsewhere.

For three years Russia had mostly refrained from attacking Ukrainian infrastructure. Electricity and heat supply operated at peace time levels. Only during the last year did attacks increase. In March 2025  President Trump announced a 30 day infrastructure ceasefire. Russia committed to it. Ukraine didn't.

In November 2015 Ukraine blew up transmission pylons that supplied Crimea. 75% of its populations were left without electricity. A brewery in Lviv celebrated that by creating a dark beer named 'Crimea by night'.
