Berwick Bank Wind Farm Could Provide Multi-Billion Pound Boost To Scottish Economy And Generate Thousands Of Jobs

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

This press release is all about numbers.

  • 307 turbines
  • 4.1 GW nameplate capacity
  • 5 million homes will be powered
  • 8 million tonnes of carbon dioxide avoided
  • Up to £8.3 billion to the UK economy
  • 4650 potential jobs in Scotland
  • 9300 potential jobs in the UK

These are all large figures.

This map from SSE shows the location of the wind farm.

The press release says this about connections to the grid.

Berwick Bank has secured a grid connection at Branxton, near Torness, in East Lothian. A second grid connection will be required for the project, which has been determined as Blyth, Northumberland.

Note, that Torness is the site of Torness nuclear power station.

  • It has a nameplate capacity of 1.29 GW.
  • It is scheduled to be shutdown in 2028.

This Google Map shows the coast between Dunbar and Torness nuclear power station.

Note.

  1. The town of Dunbar is outlined in red.
  2. The yellow line running diagonally across the map is the A1 road.
  3. Torness nuclear power station is in the South-East corner of the map to the North of the A1.

This second Google Map shoes an enlargement of the South-East corner of the map.

Note.

  1. Torness nuclear power station at the top of the map.
  2. The A1 road running across the map.
  3. The East Coast Main Line to the South of the A1.
  4. Innerwick Castle in the South-West corner of the map.

This Google Map shows the location of Branxton substation in relation to Innerwick Castle.

Note.

  1. Innerwick Castle is in the North-West corner of the map.
  2. Branxton substation is in the South-East corner of the map.

I estimate that the distance between Torness nuclear power station and Branxton substation is about five kilometres. The cable appears to be underground.

I have some thoughts.

Will The Connection Between Berwick Bank Wind Farm And Branxton Substation Be Underground?

If SSE follows the precedent of Torness nuclear power station, it will be underground.

Or will they use T-pylons?

This page on the National Grid web site is entitled What’s A T-Pylon And How Do We Build Them?.

From an engineering point of view, I suspect T-pylons could be used, but aesthetics and local preference may mean the cable is underground.

It should be noted that Torness nuclear power station will be shutdown in 2028. So will the current underground cable for the nuclear power station be repurposed after shutdown for the Berwick Bank wind farm?

This would mean, that the Southern connection cable to Blyth could be built first to support the first turbines erected in the wind farm.

When Will Berwick Bank Wind Farm Be Commissioned?

This page on the Berwick Bank wind farm web site is a briefing pack on the project.

The page gives construction and commission dates of 2026-2030.

Will There Be A Battery At Torness?

As we are talking about the latter half of the current decade for completion of the Berwick Bank wind farm, I believe that a substantial battery could be installed at Torness to smooth the output of the wind farm, when the wins isn’t blowing at full power.

One of Highview Power’s 2.5 GW/30 GWh CRYOBatteries could be about the right size if it has been successfully developed, but I am sure that other batteries will be of a suitable size.

If there is a case for a battery at Torness, there must surely be a case for a battery at Blyth.

Will Berwick Bank Wind Farm Be A Replacement For Torness Nuclear Power Station?

Consider.

  • Torness nuclear power station is shutting down in 2028.
  • Berwick Bank wind farm will be fully operational by 2030.
  • Berwick Bank wind farm could use a repurposed connection to Branxton substation, if the nuclear power station no longer needs it.
  • There is space on the Torness site for a large battery.

, it looks like Torness nuclear power station could be replaced by the larger wind farm.
