I suggest to go read this:
Still, @dominating_falcon makes a valid point. A very efficient way to major power is to:
1- Group your main power generators. I suggest on the roof top level of your factory or some other building; I use an old truck station third floor for that.
2- Place your generators so their inputs face each other and link them with splitters and, as your power demand rises, add more generatorsto the same fuel (or coal or whatever) bus line and so on.
3- Make this place a power station. Placing your generators as in point 2, their connection terminals will face outwards. Build a catwalk (foundations on around and out, with fenced catwalks outside all around for added safety). Put a power pole to the nearest point next to each generator terminal on the catwalk made of foundations (made a wall 5 sections high then added foundations out all around the top walls). Now these poles, you'll have one by generator, a Mk1 pole, you use one connection for the gen terminal, one to link to the next gen, one for the previous (except for the first and last gens) and one to link the distribution pole (point 4). this way, all your gens will be linked together. Then you make a line run all around your firsts and lasts gens, in a big loop.
4- Connect another, I recommend Mk2, at the exterior outer limit of the catwalk foundation, in line with the first pole. This second pole, you use for distribution purposes and is reachable from the floor.
In other words, your gens are linked by a fuel bus, on the outside catwalk, all around, they're linked together in a loop then you build an external distribution Mk2 array of outputs.
Fun thing with this design: - You can always add more generators without impact to your factory since it's separate and specialized, high and, hopefully, oriented so you can add more and more (I have 8, planning to go to 12 coal, also found oil so, did the same locally with fuel gens, 2 for now) you just have to remove the final cable link between your 2 last gens and expand. - You can't really run out of connections AND these connections are "all around" your station (refrain from putting in the expansion end or... yeah, reconnection headache). - Being high in the air means reachable directly however how high or how many levels your factory has...
Looks like a power spider web. I call it a Satisfactory electrical grid.
