World’s largest offshore wind farm produces power for the first time

10 Oct 2023
  • UK Prime Minister Rishi Sunak hails Dogger Bank’s role in bolstering energy security, creating jobs, lowering costs, and achieving Net Zero
  • First power achieved at UK’s Dogger Bank as the first of 277 turbines installed 130km from UK coast
  • Dogger Bank is now connected via HVDC technology to Britain’s national grid and providing renewable power to homes and businesses
  • Each rotation of the first turbine’s 107m long Haliade-X blades can produce enough clean energy to power an average home for two days 
  • When complete Dogger Bank will deliver clean energy to six million homes annually* 

The world’s largest offshore wind farm under construction, Dogger Bank, has started producing electricity for the first time for British homes and businesses, marking a major milestone in the development of the offshore wind industry and the transition to a cleaner, more secure energy system.

UK Prime Minister Rishi Sunak has hailed this landmark moment, saying Dogger Bank will bolster energy security, create jobs, lower electricity bills and keep us on track for Net Zero.

The 3.6GW Dogger Bank Wind Farm is being constructed in UK waters 70 nautical miles (130km) off the coast of Yorkshire and in three 1.2GW phases known as Dogger Bank A, B and C. The project’s first turbine at Dogger Bank A started turning and producing electricity at 8.37pm BST on Saturday 7 October. Power from the first offshore wind turbine is now being transmitted to the UK’s national grid via Dogger Bank’s high-voltage direct current (HVDC) transmission system, marking the first-time use of HVDC technology on a UK wind farm.

First power followed the installation of the first of GE Vernova’s ground-breaking Haliade-X 13MW turbines, one of the largest and most powerful globally, at the Dogger Bank site. This is the first time Haliade-X units have been installed offshore anywhere in the world.

Each rotation of the 107m long blades on Dogger Bank’s first operational turbine can produce enough clean energy to power an average British home for two days.

When fully complete, Dogger Bank’s world-record-beating 3.6GW capacity will comprise 277 giant offshore turbines capable of producing enough clean energy to power the equivalent of six million homes annually and deliver yearly CO2 savings equivalent to removing 1.5 million cars from the road*.

UK Prime Minister Rishi Sunak said:

“Offshore wind is critical to generating renewable, efficient energy that can power British homes from British seas.

“I’m proud that this country is already a world leader in reaching Net Zero by 2050, and by doubling down on the new green industries of the future, we’ll get there in a way that’s both pragmatic and ambitious.

"That’s why it’s fantastic to see the world's largest wind farm, Dogger Bank, generating power for the first time today from UK waters, which will not only bolster our energy security, but create jobs, lower electricity bills and keep us on track for Net Zero."

Rishi Sunak, UK Prime Minister

Alistair Phillips-Davies, Chief Executive of SSE, said:

“There’s been lots of talk about the need to build homegrown energy supplies, but we are taking action on a massive scale. Dogger Bank will provide a significant boost to UK energy security, affordability and leadership in tackling climate change. This is exactly how we should be responding to the energy crisis.

“But it is also a landmark moment for the global offshore wind industry, with Dogger Bank demonstrating just what can be achieved when policymakers, investors, industry, and communities work together to achieve something truly remarkable.

“The innovations this pioneering project has developed will also mean future developments can be built faster and more efficiently, accelerating the clean energy transition. Now, of course, the challenge is to accelerate the next wave of these projects and we look forward to working with governments to bring these forward as soon as possible.”

Anders Opedal, CEO of Equinor, said:

“Set against the broader energy context, Dogger Bank, the world’s largest offshore wind farm demonstrates the best of what the offshore wind industry can offer, with innovative technologies, long-term jobs and economic growth and security of electricity supply at a major scale.

“A renewable mega-project like Dogger Bank constitutes an industrial wind hub in the heart of the North Sea, playing a major role in the UK’s ambitions for offshore wind and supporting its net zero ambitions.

“First power from Dogger Bank, is a testament to the collaboration between the authorities, the project partners, suppliers and our host communities to realise this project.”

Olav Hetland, CEO of Vårgrønn, said:

“Dogger Bank’s first power milestone demonstrates that offshore wind is ready to power Europe’s energy transition.

“While today we celebrate Dogger Bank providing its first power, the offshore wind farm is delivering much more than renewable energy. The project has contributed to building industry and creating local jobs and will continue to do so over several decades. Maximising these positive local ripple effects of offshore wind projects is essential to maintaining strong support for offshore wind and the energy transition.

“Looking ahead, we expect the Northeast of England to hold a central place in Europe’s offshore wind future.”

At 260 metres tall, the gigantic turbines at Dogger Bank are almost twice the size of the London Eye and the same height as New York’s iconic Rockefeller Centre. The first power milestone marks the first of what will eventually be 277 turbines powered-up across the project. Each of these turbines will be progressively commissioned between now and full commercial operation in 2026. When complete, Dogger Bank will be the world’s largest offshore wind farm, more than two and a half times the size of the largest offshore wind farm currently in operation^.

Dogger Bank sits 70 nautical miles (130km) off the coast of Yorkshire and will occupy an area almost as large as Greater London and nearly twice the size of New York City.

World-firsts in supply chain delivery

The Dogger Bank project has delivered several world-firsts in supply chain delivery that will significantly accelerate the speed at which future offshore projects can be developed. The precision offshore installation of GE Vernova’s new 13MW and 14MW Haliade-X turbine technology was completed by expert technicians and engineers working off Jan De Nul Group's newest jack-up installation vessel, Voltaire. With a lifting capacity of 3,200 tonnes, the Voltaire is the largest offshore jack-up installation vessel of her kind in the world and the first ultra-low emissions ship of its kind.

Dogger Bank also marks the first use of HVDC transmission technology to connect a British wind farm to National Grid’s UK energy network. This includes the installation of the world’s first unmanned offshore HVDC substation platform at the site, as well as first use of Hitachi Energy’s HVDC Light® transmission system which was successfully executed in record time of 38 months with the highest safety and quality standards.

Creating local jobs

More than 2,000 UK jobs have been created or supported in relation to the construction and operation activities of Dogger Bank. Many of these are based in the north of England, where the project’s supply chain is creating long-term opportunities for people just starting out in their careers, as well as more experienced workers transitioning from other industries to renewable energy.
