The problem is that transferring energy like that requires both lines and the ability to receive the energy. Transferring has (large) energy losses, the ability to receive requires a large inertial mass, like the large and heavy turbines of the nuclear power plants.

There are/ were plans for a number of different power links, but some of them have been denied because of environmental concerns (I think! please correct me on that.)

This is the answer. It's not as simple as just laying down more cable, and it was a really hard self-own to shut down the nuclear plants in the south without anything to cover for them.
