Earlier quoted context omitted.

There is a 20 hour time difference from when the wind picks up in the UK until the wind picks up in Denmark

source? interested for the details please.

The fact that it’s 800 miles away and the weather is moving at 40mph or so?

It’s not really said in the story, but this is a bidirectional connector. There are certainly times when the UK generates excess energy from wind.

Is that rare? I naively thought that all electrical infrastructure could flow in whichever direction there was need.

For things like inverters for example, yes, you have to measure things to decide when to turn on (say) transistors based on that information. You have to carefully design it if you want to be able to drive the exact same H-bridge in reverse as a rectifier.

… and the UK has prevailing winds straight of the Atlantic.

I posted 1.5 months ago about how a potentially catastrophic grid event three years ago instead showed how successful the EU cooperation is: https://news.ycombinator.com/item?id=38251463

As an aside, the UK is still part of this but thanks to Brexit they got the opportunity to finance this interconnector by themselves and not avail themselves to the vast funds from the European Energy Programme for Recovery. For example Malta did and while the Malta Interconnector is not a world record in length but it certainly is in the relative amount: currently it's already above a quarter of the energy needs of Malta and in 2015 the relevant EU report said it's expected this to grow to 35% eventually.

Are there any safety concerns around 1.4GW flowing through a cable surrounded by salt water? I’m entirely uneducated in the ways of zap juice, but that sounds like a recipe for spontaneous electrocution if that cable breaks anywhere.

I'm not a physicist but I would imagine it dissipates quite quickly due to some inverse square law.

the UK was a net contributor to the EU

everything it "received" from the EU was paid for by itself

Think about how lightning exists, and you'll see why this is not an issue.

Time to phase out that last coal generator! https://en.wikipedia.org/wiki/List_of_active_coal-fired_powe... https://en.wikipedia.org/wiki/Ratcliffe-on-Soar_Power_Statio... Edit: interconnector already ramped to 800MW importing to the UK. Let’s gooooooooo!

Can we just agree to a phase down of that coal generator instead?
