You're living in fantasy world, that is if you even believe the nonsense you're posting.
Damn it.
I was almost “In before the Putin BoyZ”.
And there you were.
You’re quite delusional if you think Russia is winning. This is not what winning looks like.
Electric grids aren’t that vulnerable, on the whole. They are pretty tough systems.
These are distributed systems consisting mainly of power lines. These make bad targets and are generally easily repaired. There are point targets but on the whole these are akso easily repaired, given a stockpile of parts and good crews. Blowing up a substation causes mainly temporary, recoverable damage, a matter of days or weeks at most.
There are a few point targets that are hard to replace, or to replace quickly. These are major transformers, which arent in ready supply, critical power plant components, especially turbines and their casings, boilers, which though readily repairable tube by tube are not a quick fix as a whole, and a few more bits and pieces which if destroyed are weeks or months out for replacement or rebuild. Much of this probably can be imported from the EU but it remains to be seen what stockpile levels are.
All the hard to replace bits are, however, small as targets go. A big transformer can be the size of a van, but if protected by sandbags, berms and concrete (which they most certainly are by now) requires a direct hit with a precision weapon. Most of the other bits are inside concrete structures of one kind or another. And further protected by now if the Ukes are on the ball.
A power grid and its generation assets is not something that can be taken out in one volley. Damage is going to be anticipated and repair assets will be ready. It will take an extended campaign to suppress it, with constant attacks, and its likely that the repair crews will keep ahead of the attacks. Without command of the air, permitting the use of “iron” bombs, such a campaign will absorb a huge quantity of expensive long range precision munitions.
Russia doesn’t control the airspace.
