National Grid Launches Viking Link, The Next Step Towards A North Sea Super-Grid

The title of this post, is the same as that of this press release from National Grid.

These four bullet points act as sub-headings.

  • The £1.8bn project connecting the UK with Denmark was launched today.
  • With a capacity of 1.4GW, Viking Link will be able to power up to 2.5 million UK homes and is the longest land and subsea cable in the world.
  • Viking Link will deliver £5.2bn in benefits to UK consumers.
  • As the UK’s first connection with renewable energy-rich Denmark, Viking Link will be instrumental in both countries achieving net zero carbon emissions.

The press release then gives all the details of the latest of National Grid’s sixth interconnector.

As a Control Engineer, I like this interconnector.

  • Denmark and the UK are both importers of electricity.
  • The UK has 30 GW of wind power and Denmark has 7 GW.
  • The UK has almost 15 GW of solar power and Denmark has 3.5 GW.
  • The UK has 6 GW of nuclear and Denmark banned nuclear in 1985.
  • Both the UK and Denmark use large amounts of biomass to generate electricity.
  • As the sun goes East to West, Denmark will produce its daily peak solar before the UK.
  • If the prevailing winds go West to East, the UK will produce its daily peak wind before Denmark.

It looks to me that a UK-Denmark interconnector could perform a valuable job, by balancing the UK’s electricity peaks and troughs with those of Denmark.

 

The system could be improved in two ways.

  • If Southern England has a sunny, windy day, there may be need for substantial energy storage.
  • The route between the UK and Denmark could be via a large offshore wind farm in the North Sea.

Vind∅ is a proposed Danish energy island in the North Sea.

There’s more about the Viking Link on its web site.

This is the introduction on the home page.

Viking Link is a 1400 MW high voltage direct current (DC) electricity link between the British and Danish transmission systems connecting at Bicker Fen substation in Lincolnshire and Revsing substation in southern Jutland, Denmark.

The project involves the construction of converter sites and installation of onshore and offshore cable in each country. These are then connected to the substations.

Viking Link is approximately 765 km long and allows electricity to be exchanged between Great Britain and Denmark.

The interconnector enables the more effective use of renewable energy, access to sustainable electricity generation and improved security of electricity supplies. It also benefits the socio economy of both countries.

This is going to be a very valuable interconnector for the UK, Denmark and those that own it.

  1. It was run at 1.4GW import all evening last night and then switched to a modest 300MW export overnight. Since it was commissioned its imported 1.5TWh but only exported 289GWh however the ESO has had to constrain off 1.2TWh of wind already this year.

    Someone should be asking the question why that export opportunity hasn’t been taken and the simple answer is that we now have massive excess generation in Scotland and no way of sending to the south to where the interconnectors are. Yes the green link is coming but not till 2029 and by then the Scotwind sites will be coming on line so the same problem will apply. Thing is the NG worked this out a decade ago and since then independent ESO has been created they’ve been raising it as key deliverable every year in the Network Statement but its taken best part of a decade to get planning sorted and this is an asset that is largely under the sea or buried in the ground. If we are serious about net zero then the first thing that needs to be sorted is why the planning and development of these projects is taking so long

    • Let’s hope SSE and Statkraft get digging the pumped storage as well.

      Perhaps, we should build a couple of giant electrolysers in the Highlands and export the hydrogen by tanker to the Germans and anybody else who wants it.

  2. Increasing the area of wind energy is generated evens out the supply as the wind is always blowing some where.

    • Thanks!

  3. If you think the Viking Link is a long cable, take a look at https://nato-l.org/ (and I think this is just the start).
