Oh for Pete's sake, Sweden. Anything to avoid building more North-South connectivity.

Sweden is currently split into four pricing areas due to lack of grid capacity. All the cheap electricity is typically in the north (hydro) and then the price creeps up when you head south.

It's too bad the live electricity flow data is offline today, but there's a common pattern where SE1 pricing area in the north sends little under 2 GW to Finland (single zone) and most of it gets exported to SE3 around Stockholm.
