It's all well to say there should be more incentive to build data centres in the North, but physics is physics.
The reason, data centers choose to be near London is because there is no pricing advantage to go up north. Even though energy is plentiful, readily accessible, and often curtailed when there's too much of it there. If there was a pricing difference, you'd see a lot more economic activity up north.
Basically the physical advantage is there but the lack of economics cover it up and wipe out the advantage.
If it costs less up north, then there would be incentive to move demand there (for data centers, which is more location agnostic). But if the price is the same up north, then the locality becomes a deciding factor.
in a jungle there are niches, and opportunities, and even though there are very strong participants, no one is invincible, especially outside their niche.
The bankers would learn about scotland and everyone else would be better off.
