This is called re-dispatch. The market is setup up to treat Britain like a copper plate but the grid is limited north-south. The solutions are: 1. Divide the grid into two zones along the bottleneck. Then no redispatch is needed and building more capacity in the south is worth it since the prices will go up. 2. Expand the transmission grid capacity to remove the bottleneck therefore removing the need for re-dispatch.
