You want the LV/MV/HV Pneumatic Generators. The pneumatic generators take in MJ and output EU as a a near 1:1 conversion. As long as the power supply is constant, there won't be any loss of power through the conversion. You can convert EU to MJ by using either the Energy Link from Forestry (Depending on your version of course) or the Electric Engines. Considering the massive amounts of power you'll probably be sending, you'll want the adjustable electric engine since you can set it's output quite high.
