Hello, I am Trainautist, you may remember me from such threads as "how to protect a train system" or "logistics of war".
Today I would like to touch on a subject that has been on my mind for a very long time.
Power, and it's military purpose.
As we all know, electric power is necessary to run 99.99999% of all production machinery. If your nation can't produce ammunition, food or anything else, you will lose any kind of war almost instantly. Not only will your soldiers either starve, be captured without ammo, or worse, but your population will suffer immensely, sine refrigeration/freezing has almost completely replaced pickling, drying, and salting as the main method of preserving food. Hostpitals would cease to function after a week or so, without electric pumps it would take ages to fill fuel trucks, or fuel trains to transport the diesel or gas to wherever it is needed for power production or fueling trucks/tanks/cars.
As you can clearly see, protecting the power network of your nation is one of the key goals of any defensive military plan, yet there are many ways you could permanently take out power structures.
There are exactly three points of failure in the modern power structure. The power lines, transformers, and power plants.
Let me begin with power lines, since they are very similar to train lines in how to defend them. You need regular patrols, possibly on bikes or on cars. It will eat up lots of your resources, but is absolutely necessary to keep your power network going.Taking out two or three large high voltage power posts using very little explosives, or just a metal saw and a truck, can lead to a total blackout in large areas, causing trouble and confusion.
You can always lay your power lines underground, but that bears a whole other set of risks. Underground lines may be a lot harder to take out, but damages are harder to detect and repair too. All it would take would be two guys with a shovel and some explosives. They dig a hole to your power lines, bust them up, and fill the hole again before running like a swarm of bees was after them. Even if your power lines are underground, you would still need to post guards or have patrols, but in longer intervals. The deeper they are (and the longer it takes for a saboteur to dig down to them) the fewer soldiers you need to put on patrol duty,but figuring out where exactly the damage was done will be a lot harder than with overground cables, since you can't just fly a helo along them to see where one of the poles has fallen over, or a cable was cut. You need men on the ground to walk along the line and see where the ground has been dug up and hastily covered again.
The next point of failure would be transformers, but those have already been discussed to death here. All it takes is a dude with some molotows and a vespa and an entire city is without power. Posting at least four armed guards (two asleep, two guarding at all times) would be an absolute necessity. They must also have backup on standby. Again, a helo with a squad on board, or just a truck with a siren so it can avoid traffic would be ideal.
However it would also be easy to have one guy with an RPG or MANPAD ready to take out the reinforcements before they arrive. At that point you would need to worry a lot more about why your own population wants you to lose the war that badly.
The third point of failure are the power plants themselves, and they are my biggest concern in a nation VS nation war. One good hit on a nuclear, coal or hydroelectric powerplant will not only halt power generation, but in the case of nuclear power plants and hydroelectric dams, also cause massive damage to the surrounding areas. Using CIWS, and a layered AA missile system would be a clear necessity, and require lots and lots of resources. Decentralized power production, like windfarms, or solar panels would work and solve some of these issues, but especially solar farms would suffer greatly under light fragmentation bombs/artillery.
What's Zig Forumss opinion on this?
