UK announces commercial operations of longest land/subsea interconnector

There is a nice UK grid dashboard too [0]. The UK grid is actually quite variable given the amount of wind input, so imports&#x2F;exports tend to be quite twitchy depending on what&#x27;s happening - frequently going to negative and also substantially positive on pricing.<p>[0] <a href="https:&#x2F;&#x2F;grid.iamkate.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;grid.iamkate.com&#x2F;</a>

&gt; with more than four million working hours spent to get to this point.<p>A typical Brit might work 80,000 hours in a lifetime. So this interconnector is the lifetimes work of 50 people.<p>It is approximately 1 millionth of the total work output of all people alive in the UK.<p>Not sure if that is more or less than I expected...

The good thing about this is that its bidirectional, so can be used to offload ~4.2% of the total generation capacity of the UK, or should they need it, import that amount.<p>That should also cut the tops and bottoms off the spot price of electricity.

Better electrical connection to the mainland seems good all round. Denmark is electrically connected to the other neighbouring countries so this yields (indirectly) a higher current link to the rest of Europe as well.<p>Spikes in production and demand occurring at different places at different times and electrical storage being tricky makes this a good thing.

Unfortunate wording here: &quot;The cable was laid on the seabed using a custom-made vessel The Leonardo Da Vinci which was then buried using Asso trenchers.&quot;

How come Denmark can produce cheaper and less carbon intensive energy than the UK? Can&#x27;t offshore windmills be built in the UK too?

Lots of fun facts on the Wikipedia page: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Viking_Link" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Viking_Link</a><p>&gt; Annual transmission capacity of 12.3 TWh.<p>&gt; The actual cable is made of copper, steel, paper and plastic and weighs about 40 kg per meter.<p>&gt; It is similar in capacity and length to the UK–Norway North Sea Link.

Didn&#x27;t see mention of the voltage&#x2F;current specs. 1400A at 1MV maybe? HVDC is morbidly fascinating, and the gear to transform has that awesome 1950s sci-fi look.

So it has a payback period of over 3 decades. Lots of talk of all the resources spent building it, only the carbon savings of usage. I wonder how long the carbon payback is. In an era of rapidly improving renewables, this doesn&#x27;t seem like picking low-hanging fruit.

Re: cutting undersea cables. For critical infrastructure like this during cold war style conditions (i.e. Russian-NATO conflict), I wonder how pros&#x2F;cons of public vs private ownership compare...<p>For example: I could imagine sabotaging <i>public</i> infra is more akin to an attack on the state (therefore disincentized). But on the other hand, I suspect <i>private</i> interests can be more clever in protecting their investment, because they can more readily pay for high mitigation costs when consequent losses would be high.<p>Anyone else know how to thing of the tradeoffs between public vs private infrastructure here?

If you’re curious, you can follow it live on <a href="https:&#x2F;&#x2F;app.electricitymaps.com" rel="nofollow">https:&#x2F;&#x2F;app.electricitymaps.com</a><p>Right now it’s transporting ~20MW from Denmark to the UK

I posted 1.5 months ago about how a potentially catastrophic grid event three years ago instead showed how successful the EU cooperation is: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=38251463">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=38251463</a><p>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&#x27;s already above a quarter of the energy needs of Malta and in 2015 the relevant EU report said it&#x27;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&#x27;d assume this also sets the lowest price in the danish zone to the UK market price when exporting?<p>NordPool market zones are crazy and some zones see insane price surges when demand prices for neighboring zones are high.

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

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

The choice of a .com TLD instead of a .uk for a thing called &quot;national&quot; is really odd to me.

UK concerned that they’ll need the Scots to keep the lights on and so they’re ploughing British cash into a Danish interchange
