Heck, it was still exporting 2.4GW from the area facing a power shortage! A wakeup call for sure, but nowhere near a blackout.
East-west transmission wouldn't have helped here. France is less than an hour ahead, so the solar curve is going to look virtually identical. What really helped is that France had spare hydro capacity able to quickly compensate for the shortage. If anything, the UK's limited north-south transmission capacity making the use of Scotland's spare capacity impossible should be a bigger priority.
With the grid increasingly relying on decentralized solar and short-term battery storage, you just cannot operate it like you would with a bunch of on-demand essentially-unlimited fossil fuel plants. It is going to need a huge mentality shift from an operational perspective, and a large overhaul of the power trading market in general.
