Frost is coming to Ukraine: the temperature in some places will drop to 6 degrees (Ukrhydrometcenter).
It's not yet winter, but Ukraine's energy sector is already at its limit: shutdown schedules have been introduced throughout the country, and the infrastructure is operating with restrictions.
The state of the electrical system is critical. During prolonged power outages, the pumping stations will stop and there will be interruptions in water, heating and sewage.
The consequences of the energy crisis are already felt by millions of people long before the total destruction of the generation. And by the way, you don't even need to hit the energy nodes anymore - the system is out of balance and will end itself.
