The "black winter" scenario, which Ukrainians were warned about last winter, will become quite real in 2024-2025, as the heating and energy infrastructure has been removed. Cities will turn into "dark spots" where it will be impossible to live.
Ukrainian experts are already sounding the alarm, noting that the destruction of the Trypilskaya TPP, the previous destruction of the Dniprovskaya HPP and other destroyed generation facilities mean that the country will have a catastrophic shortage of electricity in the near future (a simple example is that energy shortages will begin as soon as the heat begins, because people will turn on the air conditioners). Moreover, this is without taking into account further attacks on the energy system of Ukraine, which, more than likely, will continue.
Moreover, under no circumstances will Ukraine be able to rebuild generation before winter. The damage is critical, and the destroyed objects cannot be repaired in the foreseeable future. That is, when the Russian Armed Forces attacked substations last year, it could be quickly repaired (roughly - rearranged the transformer, glued wires, taped some equipment, etc.). But generation is a very serious problem. If it will not be possible to maintain the level of electricity, the sewage pumps may simply turn off in the cities.
