Hornsea 2: The world's largest wind farm
- 165 wind turbines
- 1.32 GW of clean energy
- 1.4 million homes powered
When we initially set out to build Hornsea 2 in 2017, people said it was impossible.
The UK government awarded us a Contract for Difference (CfD) to build the offshore wind farm for what was the lowest price ever at that time.
At GBP 57.50/ MWh, the strike price was 50% lower than the previous round of CfD allocations just two years earlier.
When people saw that price, they said the business case was impossible and simply could not done.
From that moment, we knew we were trailblazers who were setting out to transform our industry. We knew we needed to set our vision and values if we were to achieve our goal.

About half-way through the project, the Covid-19 pandemic hit.
With teams in Asia, we saw the pandemic coming and set controls in place well in advance. As a result, we were able to safely continue working without interruption in the UK and at most of our global sites.
Singapore, however, was different. Due to restrictions, we had to stop work on the wind farm’s enormous 8,000-ton offshore substation there for five months. Then the special vessel we commissioned to sail the substation from Singapore to the UK broke down and got stuck in the Red Sea, delaying us by another six weeks.
Next, came the omicron variant of the coronavirus in December 2021, complicating construction. Then a month of bad weather in the North Sea in February 2022 delayed the project yet again.
Still, we dealt with every curveball we were thrown.
We overcame every challenge we met because we never measured success by the challenges we had; we measured it by how we overcame them together.
As we hand the baton on to our incredible colleagues on the Operations & Maintenance team who will keep Hornsea 2’s turbines spinning for the next 25 years, it’s amazing to look back at what we’ve achieved.
Our incredible team took an audacious idea and brought it to fruition. We managed to build the world’s biggest offshore wind farm in the demanding and unforgiving environment of the North Sea amidst the challenges of a global pandemic. Where there had previously been nothing but open sea, a wind farm will now generate enough clean energy to power over 1.4 million UK homes with low-cost and secure renewable energy.
But the most important achievement of all: We delivered on our shared vision of enriched and injury free people.
Patrick Harnett was the Senior Programme Director for Hornsea 2, the world’s largest wind farm. His next project will be leading the construction of Hornsea 3 – an even more ambitious project. With a capacity of 2.8 GW, Hornsea 3 will produce enough renewable electricity to power 3.2 million UK homes.
