They mean 'total electrical system collapse'. Incredibly irresponsible reporting from the BBC, as sadly we've come to expect.
Well, at least we know their blackstart systems work. I would have my doubts about whether the Texas grid could do a blackstart because that's stuff that's extremely rarely used but costs money--does it even exist and is it maintained if it does exist?
12,500MW - that is way lower than I expected - they clearly not industrialized.
Shouldn't someone be subsidizing solar panels over there?
It would have a lot more Co2 reduction than here, since they'd no longer be forced to use random crappy generators, it would probably save lives by eliminating monoxide poisonings, and if they're ramping up use of air conditioning that's a lot of daytime load.
