Yeah, the idea of people claiming that something on the Great Britain is too far and can't distribute power to something else on the Great Britain is laughable.

Next we'll have somebody from Lichtenstein saying the same about their country...

Well, I only said that if we're considering a ~fully renewable energy generation in the UK, with supply evened out by massive pumped storage projects, then locating all the storage in Scotland isn't ideal for the efficiency of the system. But yeah, I looked up the losses on HVDC lines, and it seems to be a non-issue (at least from a technical point of view). I also looked at a map of wind power[0] - seems concentrated on Scotland, so the distance from generation to potential storage would be quite short.
