@Jon 37. I was with you, more or less, for your first two paragraphs but the last one is a bit of a flight of fancy. GCHQ was involved with the security model for SMETS2 and there are a number of checks, etc. to prevent mass black-outs. I can't find the link at the moment but the information is out there in reasonably human-readable form.
I'm still not having one, mind you, but that's because I'm a pig-headed, stubborn old b*stard. (And I don't like the speculative and unconvincing - yet still appalling - ROI).
