Now watch how politics works ....
The pie is shrinking, so there needs to be rationing. I can't see any government risking domestic power cuts except as a measure of absolute last resort. Also I see a media battle between the government (who will try and persuade people that it's all the fault of the power companies) and the power companies (who will blame the government, the EU and "the market").
Bad move for the government, unless they decide to wade in with chequebook and legislation - the power companies will have dictated the contractual landscape, and made sure it's industry that goes offline first. Factories, big office complexes (and hopefully a few government departments ;) ). At which point (those of us who remember the 3 day week) you will start seeing the lay offs.
And that's the price you pay for not educating the population properly AT SCHOOL so they had enough grasp of science to debate nuclear power rationally. Still, maybe if we burn a few media studies graduates, we can keep some lights on.
I grew up in the 70s, and recall getting home from school, and lighting the candles for when my Mum got home from collecting brother from playschool. Giving thanks for a gas cooker (a preference I have never lost) and for my Dads inna te distrust of electricity (he was born in Southern Italy, where power cuts are a way of life) which meant he insisted on gas central heating. Being a real engineer, he rigged it up to run off a car battery, so it could run without mains.
No power cuts in the 80s, no power cuts in the 90s, but in the past 4 years we have had at least 3 outages of over an hour. My suspicion is lack of capacity makes it harder to route around stolen cables.
