The problem is mostly discussed in Germany in context of north vs. south - the north with the coast and all its wind parks, and the energy-hungry, industry-rich south. Right niw the solution is to build new power lines, but that spawned a huge political debate (NIMBY). Power lines are about as unpopular as new freeways, and there is a risk of court cases dragging on for years, stalling the energy transition program. The compromise right now is to spend more tax money and use underground cables in densely populated or otherwise sensitive areas (e.g. nature reserves).
