1/ Russian targeting of power infrastructure in Ukraine has expanded to systematically hit open switchgear associated with hydroelectric power stations and the boilers of thermal power plants, in an attempt to reduce overall resilience, according to the Rybar Telegram channel. ⬇️

2/ In a series of posts, Rybar analyses the impact of today's missile strikes. It comments that the aim of the attacks was "to deprive the enemy of the opportunity to compensate for the energy deficit" resulting from previous attacks. The targets included:

3/ 💥 An open switchgear of the Kaniv hydroelectric power station in the Cherkasy region.

Rybar comments: "The hydroelectric power station is located on the middle reaches of the Dnipro, helps to compensate for the energy shortage in the Kyiv region ...

4/ and at the same time has the ability to transfer the generated electricity to the east of the country through the switchgear of the Kremenchuk hydroelectric power station."

5/ 💥 An open switchgear at Kremenchuk hydroelectric power station (HPP).


Rybar comments: "This is the third HPP on the Dniepro with a capacity of 686 MW.

6/ Power consumers in the east and centre of the country are supplied from the HPP through an open switchgear of 330 kV.

7/ The switchgear itself is a key point of the 330 kV high-voltage line stretching through Kryvyi Rih (PS Pervomaiskyi 330), Cherkasy (PS Cherkasy 330) and the east of the country (SS Kremenchuk 330).

8/ A blow to the substation reduces the possibility of transmitting electricity to the industrial areas of Kryvyi Rih, Cherkasy, Poltava and part of Kharkiv regions."

9/ 💥 The boiler room of Prydniprovska thermal power plant (TPP).

Rybar comments: "Judging by reports from the field, the station has ceased to function: there is no smoke from the main two pipes.

10/ Strikes on boilers at a power plant are the most critical, since the boilers themselves are quite large, high pressure is created in them, and damage is very difficult to eliminate.

11/ In addition to the failure of boilers at the Pridneprovska TPP, damage to process pipelines is possible: this creates even more difficulties in organizing repair and restoration work.

12/ The disabling of the Prydniprovska TPP, along with today's attack on the switchgear of the Dniepro hydroelectric power station, further complicates the situation with the electricity supply in eastern Ukraine."

13/ 💥 The 330 kV Pravoberezhna substation, connected with the Dnipro hydroelectric power station (DniproGES).


Rybar comments: "The Dnipro HPP is the most powerful of the power plants located on the Dnipro (capacity 1548 MW).

14/ A large node provided a significant role in the generation of the region after the shutdown of the Zaporizhzhya nuclear power plant.

15/ Wherever the rockets hit, the damage will still be significant, since it will still be extremely difficult to use it at full load – even if the generators were not damaged."

16/ 💥 The Zalyutyne 330kV substation in Kharkiv region.

17/ Rybar comments: "The substation was already hit – autotransformers were put out of action each time (although in total there were already more hits than autotransformers at the substation, but these are mere nuances).

18/ Zalyutino Substation provides electricity transmission from Kharkiv Combined Heat-and-Power Plant (CHPP) No. 5 and Zmiivska TPP. After the strikes, trams, trolleybuses and the metro stopped working in the city, and electricity was partially lost."

19/ 💥 The Vyshhorod 110/10/6 kV substation, connected to the Kyiv hydroelectric power station.


Rybar comments: "Kyiv HPP is a large power plant on the Dnipro with a capacity of 440 MW, the very first in the Ukrainian HPP cascade.

20/ It feeds the power system of Kyiv through the Vyshhorod 110/10/6 kV substation.

A blow to the substation will reduce the possibility of using it to stabilize the power supply to consumers in Kyiv and the north of the Kyiv region."

21/ 💥 Open switchgear of the Dniester HPP-1 in western Ukraine.

Rybar comments: "Dniester HPP-1 is the most powerful power plant on the Dniester cascade (702 MW). Along with the Ladyzhinska TPP, it is the main source of energy in the southwest of the country.

22/ Through the 330 kV outdoor switchgear, which is the most important nodal point of energy distribution, energy is distributed in the south of Ukraine, there is a 330 kV transit line to the Chernivtsi and Ivano-Frankivsk regions.

23/ It is not yet known where exactly the impact occurred, but judging by the smoke, the 330/110 kV autotransformer was most likely hit." /end
