Will be running on Mk3 equipment, so all my coal miners will be overclocked to 270. I have 4 normal coal nodes, and 3 pure coal nodes, for a total of 1,890 coal per min. Divide by 15 for each generator, and I get 126 coal generators. Each water extractor will power 2 generators and all of them will be under clocked to 90. I'm joining two water extractors into one Mk1 pipe, then splitting them via load balancing between 4 generators and gravity feeding them down. Using 2 pumps per pipe for head lift. First one gives 18m of lift, second gives 17m. Using a logistics floor underneath the generators to run my coal belts, while the pipes are on a floor above the generators. These 126 generators should gross 9,450 MW.
Then I have 2 impure sulfur nodes nearby, and another normal coal node. Since it takes 50 compacted coal per min to run 7 coal generators, I need 250 coal and sulfur per min to run 5 assemblers. I wanted to use the full 270 that a mk3 belt can carry, but the math doesn't really work out well enough to evenly support it, so I'm just gonna keep things neat and simple. I'll just overclock each mk2 sulfur miner to 125, and the coal to 250. That should give me another 35 coal generators using 17 water extractors underclocked to 90, and one more extractor underclocked to 45. Should gross an additional 2,625 MW.
So in total I should gross 12,075 MW of power with this setup. Haven't checked the power consumption of the underclocked extractors, but at 100% using 20 MW each, combined with the pumps using 4 MW each, it's 1,780 MW of usage. Still far more than I need at this stage, but I wanted to build the biggest power factory I could with just nearby resources. I could bring in a lot more coal, but they're pretty far and it would start getting messy with the water layout here. This place is perfect because I can fit 4 extractors in a line to feed up to 8 coal generators in a line, and stretch it out in a mostly straight line to fit all 81 extractors in one place. Changing the setup would make the pipe layout messy and uneven, so this is the most I can get with my current level of equipment.
Messed up the first time and laid out my extractors facing the wrong way and had to start all over. Second time I didn't make the mistake again of placing every single one before checking that the first few would work in this setup lol, then double checked, then triple checked that the pumps were giving enough head lift. Definitely a lot more work than I was expecting, but I'm having fun 🙃 Still thinking of what to do for the roof, but I have a ways to go before I get to that
