depending on your situation, powerconverters turning eu into mj pumped through tesseracts then converted back on the far end is an option, although by default config, tesseracts would eat 25% of the through, and cap at 100mj each.
personally i just increase the through limit and set fire to a few sacrificial tesseracts as need be.
you might also consider generator arrays and simply tesseracting the fuel to the far end. maybe thermal generators/diesel/etc and having turned your eu into lava or oil or biofuelsomesuch with mfr machines?
