in the distances we speak about we do so all the time with more centralized energy sources (like e.g. nuklear) due to their centralized nature

the issue is less the transport distances but changes in "from where to where" sometimes needing some extensions/improvements to the power grid. Through commonly in ways which anyway make sense and all pretty much "standard" solutions well understood. Through there are some more complicated exceptions to that.

EDIT: "distances we speak about" assumed less many local less dense populate/suitable spots across the EU, not a mega project like a energy pipeline from North Afrika.
