❗️🇷🇺🇺🇦 How the Russian Armed Forces managed to destroy Odesa's energy sector — Rybar and Military Chronicle’s analysis
In Ukraine, the consequences of previous missile strikes on energy infrastructure facilities have been almost completely eliminated: outdoor lighting always functions, and scheduled power outages are gradually being cancelled.
With this in mind, the Russian Armed Forces' strikes seem pointless, as Ukraine repeatedly claims that it has managed to handle the problem with power supply. In fact, this does not correspond the reality. The #Odesa case shows this in practice. In fact, this is the first Ukrainian region, the power system of which was damaged critically.
🔻 How is Odesa's power supply system arranged?
The 330 kW power distribution is organized through one key node, the #Usatove substation.
#Novovodeska and #Adzhalyk substations were also hit: one of the two 330/110kW autotransformers was hit. A similar situation is developing at the #Artsyz substation.
According to open sources information, the total transformer capacity with its own generation is only a third of what it was before, about 471.7 MW (of 1332 MW). This is critically insufficient for Odesa.
🔻 Do preventive shutdowns help?
It helps minimize damage in the event of an attack, but if there are no strikes, it only makes it worse. Every shutdown causes overvoltage. As a consequence, not only 110 kW and 35 kW equipment and transformers fail, but also medium voltage - 10/0.4 kW and 6/0.4 kW - necessary for normal city life.
The constant switching on/off of equipment causes damage, sometimes comparable to the impact itself, but in this case not point-to-point, but distributed throughout the network. It can take a long time to restore power, and the city is transferred to generators. In a sense, declaring an air alert in this case is more dangerous than the strike itself.
🔻 What are Ukrainian energy companies doing?
DTEK's main efforts are focused on several areas:
➖Maintaining the remaining high-voltage equipment
➖Maintaining the equipment in function
➖Restoring 110, 10 and 6 kW networks
❗️ 330 kW networks are the most difficult to restore. They are repaired on a spot basis to maintain the minimum functionality of the substation. But it is impossible to replace autotransformers now.
Because of the restoration of low-voltage networks, the need to power from a limited number of substations increases.
This leads to mains voltage drops, which are compensated for by a rise in voltage at the power transformers. However, as new substations are switched on, the drop stops, and the high voltage transformers remain unchanged. It turns out that in apartments and houses of residents the level rises to 260-270 W instead of the usual 220 W - and further loads the power grid.
🔻 Prospects
The strikes on Ukraine's power system, despite their non-obviousness, are bearing fruit, which is most seriously felt in the Odesa region. If the strikes continue, the city's energy system will simply fail, and the region will be isolated from the general grid for a long time - from several weeks to several months.
In theory, this will limit the transfer of personnel and equipment from #Romania and #Moldova by rail and reduce the logistics capabilities of the Odesa port. But this is a double-edged sword: the energy crisis may push the AFU to seize the Cuciurgan power station in #Transnistria.
The deterioration of the situation will put even more pressure on the local population: discontent is growing every day. And the forced mobilization of citizens exacerbates the situation in the region.
❗️ Odesa region is the first one where the plot to destroy the energy infrastructure has succeeded, bringing about military and political changes.
