The Russian military began large-scale precision missile strikes on Ukrainian infrastructure, military communications and command posts on Monday, in retaliation to Saturday’s terror attack against the Crimean Bridge and other acts of terror attributed to Kiev. Russia today, Tuesday, is continuing its campaign of precision missile strikes on Ukraine, the Ministry of Defense has indicated.
🔻 The vulnerable spots of the power system are the 750 kV substations.
➖ Most of the nuclear power plants are located in the west of the country. It is the most stable element in the Ukrainian energy system.
➖ In the centre of Ukraine there are thermal power plants and the Dnieper cascade of HPPs. The operation of Ukrainian HPPs is highly dependent on the water level in reservoirs, and the failure of one or more dams can severely reduce the amount of energy generated.
➖ The eastern regions of the country are powered by thermal power plants. Because of coal shortages, thermal power plants cannot be considered a stable link in the energy system: they may simply run out of fuel.
🔻 Strikes on 750 kV open switchgears will disrupt the entire Ukrainian energy system. Large sources, especially nuclear power plants and thermal power plants, would be isolated and shut down.
As a result, even the west of the country, where the Rivne and Khmelnitsky nuclear power plants are located, will feel power shortages. There is already talk of rolling blackouts in some Ukrainian cities.
🔻 It will not be possible to restore power grids near nuclear power plants quickly. With winter looming, grid failures will have catastrophic consequences.
▪️ The Kievskaya-750 substation. It transmits electricity from Khmelnitsky and Rivne NPPs to the central and eastern regions of Ukraine.
Autotransformers: 50.493278, 29.691278;
50.493000, 29.695083;
▪️ Vinnitsa-750 substation. It distributes power from the South Ukraine NPP to the west and centre of the country.
Autotransformers: 49.164500, 28.722056;
▪️ West Ukrainian-750 substation. It distributes electricity from the Rivne, Khmelnitsky and South Ukrainian NPPs to Hungary. Autotransformers with capacity of 1000 MVA.
Autotransformers: 49.385944, 24.247639;
49.385889, 24.249222;
49.385833, 24.251750;
▪️ Dniprovskaya-750. It is used to distribute power from the South Ukraine NPP to the million-strong cities of Dnepropetrovsk and Zaporozhye.
Autotransformers: 48.434722, 34.036333;
48.436056, 34.035972;
▪️ The Zaporozhye-750 substation receives power from the South Ukraine NPP, it is closest to the front.
Autotransformers: 47.998944, 35.508417;
48.000667, 35.508028;
▪️ substation Severo-Ukrainskaya-750. Energy bridge to Russia, to KNPP, power transmission from Rivne and Khmelnitsky NPP through Kiev substation to Kharkov.
Autotransformers: 50.690056, 33.769361;
▪️ NPP OPEN SWITCHGEAR. The WSU strike on the open switchgear of Zaporizhzhya NPP showed the effectiveness of this approach because open switchgear is critical to any power generation system.
If the open switchgear of the Rivne, Khmelnytskyi and South Ukraine NPPs were to be hit specifically, the Ukrainian power system would be severely damaged.
750 kV outdoor switchgear of the Rivne NPP: 51.321400, 25.918435
750 kV switchgear of Khmelnitsky NPP: 50.296547, 26.643720
750kV switchgear of the South Ukraine NPP: 47.819796, 31.228414
❗️At the same time, impacts on 330 kV substations should continue, which could partially compensate for the inability to use the 750 kV substation.
The more substations that are taken out of service, the greater the shortage will be. Nearby nuclear and hydro power may be generated but there will be no one to consume it, and where there will be consumers, there will be no generating plants.
