Ørsted Awarded Contract For World’s Single Biggest Offshore Wind Farm

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

This is the sub-title.

The UK Department for Business, Energy and Industrial Strategy (BEIS) has awarded Ørsted a contract for difference for its Hornsea 3 offshore wind farm. The project was awarded at an inflation-indexed strike price of GBP 37.35 per MWh in 2012 prices.

And this is the first paragraph, which describes the size of the farm.

With a capacity of 2,852 MW, Hornsea 3 will produce enough low-cost, clean, renewable electricity to power 3.2 million UK homes, making a significant contribution to the UK Government’s ambition of having 50 GW offshore wind in operation by 2030 as part of the British Energy Security Strategy. 

This map from Ørsted shows the location of the Hornsea wind farm and its three sections.


  1. The Hornsea Wind Farm, when fully developed, with a fourth section, is likely to have a capacity of around six GW.
  2. The Lincs, Race Bank and the Westernmost Rough wind farms are about another GW.

Looking at the map, I can see Humberside hosting the world’s largest hydrogen electrolyser to feed into the Humber Zero hydrogen network.

  1. Yes it has the potential to power 3.2m homes but not continuously and more wind on the system needs more frequency response services which is largely being delivered by batteries that aren’t available for long term storage which will become our Achilles heel soon with higher wind penetration. NG ESO have also released there holistic system design to support 30GW of wind and that needs 7B of expenditure over and above whats already been agreed. They do say if fully built out it will eliminate constraint constraints so pay for itself but it needs approach from 1950’s just build it don’t spend 5-10 years developing it and getting approvals.

  3. It looks like power from 1 & 2 is being brought into substations at Killingholme power station, as on the map you show, but 3 is being brought to the Norfolk coast and Norwich Main substation (which is S of Norwich).
