Electricraft should be able to do that on its own, though without ReactorCraft to generate lots of power in one place, it's probably easier to just transport fuel to individual engines on each of your machines.
In any case, you should be able to use EC generators and engines (whatever they're called) in much the same way you'd use magnetostatics and rotational dynamos. Use various cables (warning, the uninsulated ones can and will electrocute you and destroy items) to connect them together, and use resistors to limit the voltage to various things (and no, I don't know the system well enough to know why you'd want to do that, other than to be able to use cheaper cables). Pretty sure Reika's made a video or two showing it off.
Also, EC's Auroral Battery, while incredibly expensive, stores a HUGE amount of energy. I don't know the numbers off the top of my head, but if you search this very forum, you should be able to find them.
