Depending on North Africa which is extremely politically unstable is a horrible idea. Germany is phasing nuclear energy out. EGV is just a vision: reality is Germany routinely overloading their neighbors' grids(Czech, Polish) transmitting electricity from northern wind farms to southern and Austrian industrial centers. The neighbors are quite upset about it and are taking legal and technological(expensive investments on borders, without any German participation).

The endgame for Germany is wind + Russian gas, see Nordstream2.
