The lines are sort of arbitrary in a geographic sense as in reality they are defined based on the intersection with the schematic version of the transmission network [0]. Though yeah, that specific example is an odd one and I'd be interested to understand more about why it was placed in one boundary and not the other.

Lovely site. As a wind energy ignoramus, it would be great to add descriptions to your FAQ for the red lines, and curtailment.

		I'll make sure to get the about page updated soon, it's been a bit neglected with being so focussed on the recent upgrades. Definitely a lot I can explain better, and also ways that I can solve that with better UX in general.
