What is the point of endgame tekkit?

I really have been looking at what the point of nuclear reactors and high power energy generators are really mean't for what are you trying to power nothing I can see really needs that amount of power unless its for an array of machines.

I really want to know is why would I build a nuclear reactor or better to power uninteresting machinery

Mining Lasers are quite power hungry. Assume you are are referring to the 1.6.4 Rocketship tekkit.
