Transporting EU over a distance is easy with Glass Fibre Cables and HV. Or you could save even more energy and use Insulated EV Wire with EV.

In any case, transporting EU over long distances is substantially easier than transporting MJ. And because Electrical Engines and whatnot can run off of EU, it's more feasible to use a system such as this for a power grid.
