> From 1 January 1974, commercial users of electricity were limited to three specified consecutive days' consumption each week and prohibited from working longer hours on those days. Services deemed essential (e.g. hospitals, telephone switchboards, supermarkets and newspaper printing presses) were exempt. Television companies were required to cease broadcasting at 22:30 to conserve electricity [...] The Three-Day Week restrictions were lifted on 7 March 1974.

We're currently paying a lot more than usual because:
1) we have to pay off operators for the billions of foreign investment they put into new wind and solar farms and grid storage batteries. If we didn't tempt them with a good RoI, they'd invest elsewhere, and we'd still be burning coal. The cost of this is going down year on year: https://en.wikipedia.org/wiki/Contracts_for_Difference_(UK_e...
2) we're paying for new transmission capacity and replacing worn out transmission route. The fact we don't already have it, which we could've had by charging more for electricity in the 2000s and building it out decades ago, is why today we face enormous curtailment costs today, as we can't get all this wind power from where it's generated to where it's consumed: https://www.telegraph.co.uk/business/2026/10/05/the-bottlene...
3) our market arrangement is based on everyone bidding to supply power, and we pay everyone who generates the same rate as the highest necessary bidder. Thus the moment that there isn't enough wind power, or there is but it can't get to the region it's needed (see point 2), in come the gas turbines and given that Russia's trying to destroy Ukraine, gas is astronomically expensive. The sooner we solve our bottlenecks and decommission all the gas turbines, the better.

In the '70s you weren't guaranteed to get the electricity you paid for:
