£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…

I don't know if the UK government paid the full amount, but £50 million a year for £1.7 billion is a 2.9% interest rate, which is approximately sensible.

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't seem like picking low-hanging fruit.

It's done by NGV, which was described as:

    NGV develops, operates and invests in energy projects, technologies and partnerships
    to accelerate the development of our clean energy future.
Maybe they're one of those places which invests in developing infrastructure tech, to pave the way for subsequent generations?

If you’re curious, you can follow it live on https://app.electricitymaps.com Right now it’s transporting ~20MW from Denmark to the UK

Interesting.

The map seems buggy for Canada. The "Country" map for Canada seems to be wrong, as it looks like it's subdivided into several pieces (as if it was the "Zone" view).

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. That should also cut the tops and bottoms off the spot price of electricity.

Which could theoretically supply nearly half of Denmark's electricity demand, at peak transfer.

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...

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.

Re: cutting undersea cables. For critical infrastructure like this during cold war style conditions (i.e. Russian-NATO conflict), I wonder how pros/cons of public vs private ownership compare... For example: I could imagine sabotaging public infra is more akin to an attack on the state (therefore disincentized). But on the other hand, I suspect private interests can be more clever in protecting their investment, beca…

AFAIK attacks on sufficiently important private infra is also considered an attack on the state. There is no meaningful difference, other than the scale of the attack and the importance of that infra. The main defining factor in how the state responds to such an attack is whether escalation is in the interest of the victim. E.g. recent attacks on commercial ships in the Red Sea.

Yeah thanks for stating it clearly. That distinction makes sense to me too :)

No. The connection is 1.4 GW and Denmark typically use 4 to 5 GW. See https://energinet.dk/ (scroll down to map at look at "FORBRUG I DK")
