Earlier quoted context omitted.

They can, and the UK is one of the largest builders of offshore wind. But Denmark has spare capacity, and UK electricity prices are high.

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.

There is a nice UK grid dashboard too [0]. The UK grid is actually quite variable given the amount of wind input, so imports/exports tend to be quite twitchy depending on what's happening - frequently going to negative and also substantially positive on pricing.

How come Denmark can produce cheaper and less carbon intensive energy than the UK? Can't offshore windmills be built in the UK too?

Offshore is more expensive than onshore wind, which has been effectively banned across most of the UK.

> with more than four million working hours spent to get to this point.

A typical Brit might work 80,000 hours in a lifetime. So this interconnector is the lifetimes work of 50 people.

It is approximately 1 millionth of the total work output of all people alive in the UK.

Not sure if that is more or less than I expected...

Unfortunately, Denmark has many of the same winds as the UK, so on the exact same days the UK has excess power, Denmark doesn't need power...

Will this finally decrease some of these bills? Or will this just mean even more record profit for the energy companies?

“ It will bring more than £500 million in savings for UK consumers in the first ten years.” If you believe that I have a monorail to sell you! Why pass onto consumers what you can take as profit. Norwegian news is reporting that the price of electricity will increase a tiny amount (about £10-15 a year) in both Norway & the UK as an increased flow of power means more bidders for it, pushing the price up when power is…

That's about 15p per month per household

Didn't see mention of the voltage/current specs. 1400A at 1MV maybe? HVDC is morbidly fascinating, and the gear to transform has that awesome 1950s sci-fi look.

Currently it’s only 800MW at 525KV but eventually they’ll bump that to 1,400MW so 2,700A if my math is right?

It’s bipolar (+- 525 kV) according to W

The ‘Viking Link’ connector, projecting Danish power across the North Sea… I feel a song coming on… Aaaa-aaaaaa-ah! Aaaa-aaaaaa-ah! It comes from the land of the ice and snow From the midnight sun where the cold winds blow The hammer of the gods Will turn the blades of turbines To light the grid, sing and cry Wind power, I am coming…

My attempt:

(Tune begins with a rising, powerful melody)

Verse 1: From the shores of the Danes to Britannia's realm, Where the sea meets the sky in a watery helm, There's a thread made of power, so silent and sleek, A marvel of might that the ancients would seek.

Chorus: Oh, Viking Link, your cables enfold, Uniting the lands as the sagas once told. Electric currents, like legends of old, Viking Link, forging futures so bold.

Verse 2: Beneath the North Sea where the mermaids do sing, Lies a path of pure energy, a power-bringing string, Connecting the heart of the emerald isles, With wind-harnessed force that covers the miles.

Chorus: Oh, Viking Link, your currents so free, Dance 'cross the depths of the deep, briny sea. Blending the watts as the mead-masters would, Viking Link, for the greater world's good.

Bridge: Hark! As the turbines spin round and round, A whisper of Odin, in kilowatts found. Thor might have thundered with fierce, mighty sound, But our silent giant lies under the ground.

Verse 3: From the fjords where the Vikings once launched their great fleets, Comes a new age of conquest, where technology meets. And the UK replies with welcoming hands, Together they stand, where power demands.

Final Chorus: Oh, Viking Link, your saga's begun, Tales of electrons, from dusk until dawn. May your current flow steady and strong, Viking Link, in our hearts, your song lingers on.

(End with a triumphant harmony)

£500 million over 60 million people over 10 years is £1 per person per year. I can believe it.

But we had to spend 1.7 billion. So looks like we need to wait 37 years for payback…
