I thought that one reason for shutting down steel production in this
country was to release electricity generation capacity to avert
blackouts this winter. (possibly I'm being cynical, but I don't have any
figures to hand)

I'm not following this bit. 57 MW is a nats fart as far as a 54,200
MW demand is concerned. I've watched an ammeter in a grid switching
center near Cardiff gently waving about by 10 A or so, probably a 275
kV line so 2.7 MW and that's just the variation in demand over a few
tens of seconds of one medium city...

5.1% of 54.2 GW is 2.7 GW.
if 5.1% is 57 MW 100% is 1.1 GW.

Is the truth they want 1 GW (ish) above demand as margin and they are
forecasting only 5.1% of that 1 GW being available?

57MW did strike me as being rather low. I would have thought, for
example, at 5pm now it's dark and the lights will be coming on, people
will be going home and putting the heating and evening meal on, that a
57MW margin would be far too little.

Maybe it's Grauniad journalism at its finest again.

That thought *did* cross my mind.

That's more likely I think. If a station trips out or an unexpected
demand increase appears, they'd be stuffed with 57MW of reserve.

Even 1GW of reserve is wobbly pants time if (as happened in 2008)
something the size of Sizewell B trips out.

Yes we are sailing close to the wind. I suspect some will come in from
France though, assuming we are not at war with them by then.

That's already included, and of course when the wind isn't blowing here,
the wind is generally not blowing on la continent.

survival, to indulging in navel gazing and faux moral investigations
into what the world ought to be, whilst we fail utterly to deal with
what it actually is.
