I just use a Big Reactors setup whenever I play on my kinda private server. One wall has 5,000 energy outputs leading to my million Resonant Energy Cells. One wall has 50 reprocessors, several Yellorium inputs, several Cyanite outputs, three Blutonium inputs, my redstone control and my manual control. The other two are simpler, one is reactor glass, the other my 'credits wall' with the names of the hundred players that helped me construct my 1,202 by 1,202 by 252 reactor. Took us months, but we made a reactor that can support ninety quarries at max speed, 340 MFR laser miner things and plenty of TE3-addicted players with power to spare.
