How does our power system work and what does the enemy hit?
The first thing we need to know is that the power system generates exactly as much as the entire country consumes. NEITHER A WATT MORE NOR A WATT LESS.
Nuclear power plants generate the most electricity. This is the cheapest electricity in Ukraine.
Their main disadvantage is that you cannot change the volume of generation dramatically. NPPs don’t like it when generation is increased, let alone when it is sharply reduced. It is dangerous for them.
The enemy knows this, so it tries to hit the pain points of the power system to plunge Ukraine into darkness:
(1) Transformer stations near nuclear power plants. Especially 750kV transformers, because they are almost impossible to repair (because only the Russian Federation, Central Asian countries, and Zaporizhzhya Transformer Plant make 750kV transformers).
If a transformer station is destroyed, it will not be able to transfer a LARGE chunk of generation and will go into emergency shutdown. Each emergency shutdown greatly reduces the life of a nuclear power plant.
(2) Key transportation hubs. The network is a “web” where everything is connected.
If several nodal substations are affected at the same time, the system will go into a severe imbalance of areas (where either too much electricity is generated or consumed much more than produced), which will cause the automation to shut down generating capacities or load.
To prevent an accident from occurring and equipment from being damaged in the event of a power surge or rapid voltage drop, the automation simply shuts everything down.
Thus, Destroying several nodal power plants can trigger a cascading blackout across the country, when everything goes down for a while.
This is exactly the goal of the gun and it hits these two types of targets!
In just 2 days, about 150 missiles were fired at our energy sector.
Even a dozen missiles that arrived could have caused significant damage to our energy system and caused a blackout of most of the system, which would have to be “raised” for several days.
The leadership and the Armed Forces are actively working to develop a system of defense and infrastructure repair that will allow us to consistently repair faster than they destroy.
However, ordinary citizens should also join in the defense of the Ukrainian energy system.
