MEMBER NEWS: Hywind Scotland remains the UK’s best performing offshore wind farm

For its third consecutive year, Hywind Scotland – the world’s first floating offshore wind farm – reaches the highest average capacity factor for any wind farm in the UK. With an average capacity factor of 57.1% in the twelve months to March 2021, the floating offshore wind farm set a new record in the UK.

During its first two years of operation, the wind farm achieved an average capacity factor of 54%. That compares to an offshore wind average in the UK of around 40%. The capacity factor is the ratio of actual energy output over a given period of time, to the maximum possible output.  A higher capacity factor means lower intermittency and higher value.

With this top of the charts performance, the Equinor-operated wind farm has truly proven the potential for floating offshore wind, paving the way for the UK’s announcement of 1GW of floating offshore wind to be developed in the UK by 2030.

Equinor is the global leader in floating offshore wind. With Hywind Tampen onstream in 2022 Equinor will operate a third of floating offshore wind production worldwide.

“In Equinor we are constantly striving to improve the performance of our assets, whilst ensuring we extract learnings to support future projects. The turbines on Hywind Scotland are covered in sensors, to extract as much data from the wind farm as possible. We’re monitoring everything from ballast, mooring, structural strains and the more regular wind turbine sensor data, looking at how best to optimise this innovative technology as we prepare to develop at scale. We’re sharing parts of this data across industry to help the advancement of the technology globally and more widely than just our own operations,” says Sonja Chirico Indrebø, plant manager for Hywind Scotland and Dudgeon, the bottom-fixed wind farm off the coast of North Norfolk, who also can show to strong results.

As the first project of its kind, the Hywind Scotland wind farm has provided valuable data and results that will help drive the whole industry forward.

“It’s great to see the results Hywind Scotland and the floating technology keeps delivering. The potential for floating offshore wind is huge. With access to deeper waters and therefore higher and more consistent wind speeds, floating offshore is not only an efficient way to generate electricity from wind, this exciting technology can also provide jobs and value creation for the countries supportive of floating. In the UK alone, we are talking at least 17000 jobs and £33bn GVA by 2050. We believe Scotland has the potential to build a globally competitive offshore wind industry, including a real chance to enhance the development of floating offshore wind,” says Sebastian Bringsværd, head of floating wind development at Equinor.

As a global major in offshore wind with decades of experience in developing offshore energy – oil and gas, Equinor is uniquely placed to drive forward global deployment of floating offshore wind.

In 2009, Equinor installed the first ever floating offshore wind turbine, and Hywind Scotland followed in 2017 as the world’s first commercial floating offshore wind farm. It is now developing an even bigger project, Hywind Tampen, situated off the coast of Norway. This project, currently in construction, is on schedule to become the world’s largest floating wind farm as well as the first project ever to use wind energy to decarbonise offshore oil and gas production.

A recent report from ORE Catapult showed potential pathways for the growth and cost reduction for floating offshore wind.

Scale is key to cost reduction and Equinor has already seen a reduction in CAPEX per megawatt of 70% between its initial demonstrator, with a capacity of 2.3MW and Hywind Scotland, with a capacity of 30MW. The company expects a further 40% drop between Hywind Scotland and the 88MW Hywind Tampen.

“The global energy industry has been pleasantly surprised by the rapid decline in the cost to deploy fixed bottom offshore wind. We’ve been working on floating offshore wind for more than ten years and we see that significant cost reductions can be achieved through scale and experience, paving the way for floating to become fully commercialised”, says Bringsværd.

Job creation

In the UK alone it is estimated that up to 17,000 jobs and £33.6bn of GVA  could be generated by this innovative technology by 2050. The new areas floating offshore wind unlocks means the economic benefits of offshore wind will spread further, delivering long-term skilled jobs in places unsuitable for fixed bottom offshore wind.

The UK has become one of the first countries to set a formal target for floating offshore wind, committing to 1GW by 2030. However, Equinor and others in industry are confident that we can go further than this, reaching up to 2GW by 2030 and building a multi-GW pipeline of projects to deliver the UK’s longer-term net zero objectives.

AREG is the original energy transition organisation, working on behalf of members to empower the energy supply chain and champion its expertise. Please get in touch if you have any questions or would like to find out more about membership.

AREG has played an important role in the growth of Scotland’s renewable energy sector, engaging the supply chain and developing the European Offshore Wind Deployment Centre. However, we are only at the very beginning of the transition that AREG was established to both lead and support so there are still opportunities for companies to get into the constantly evolving renewables supply chain. We look forward to continuing our work together as renewables builds on its place as Scotland’s main source of power, and as we seek to deliver real change in the crucial areas of heat and transport.

Aberdeen & Grampian Chamber of Commerce has worked closely with AREG since its formation. The recent progress in the developments of offshore wind projects by Equinor and Vattenfall are as a result of the work of the group over many years. The north-east is known as the oil and gas capital of Europe. At the Chamber, we believe the region must evolve its position to being recognised as the energy capital. Whilst hydrocarbons will continue to be essential in driving our economy for years to come, the generation of renewable resources will play an increasingly important role in providing cost-effective power, innovative development and economic growth.

The enthusiasm and dedication of the early group that would become AREG was fundamental in us choosing to launch All-Energy in Aberdeen. The first tiny show was held in 2001, and AREG’s Chairman at the time, Jeremy Cresswell, played such an active role that I often describe him in terms such as All-Energy’s ‘midwife’. All-Energy is now the UK’s largest renewable and low carbon energy exhibition and conference in terms of number of attendees, space booked, and number of exhibiting companies. As AREG became firmly established, their presence and support for the event grew spectacularly over the years. We thank them most sincerely for their invaluable input.


Vattenfall has forged a strong working relationship with AREG through the development of the European Offshore Wind Deployment Centre. AREG has worked tirelessly on behalf of the North East and it can take enormous credit for the growth of sustainable energy in the region and the path it has cleared for the region to capture further investment.


Aberdeen City and Shire is emerging as a key location for renewables by successfully transferring its world-class oil and gas expertise into the sector and AREG has done much to advance this through a broad range of initiatives. It has acted as a catalyst in driving further investment in the local economy by engaging with companies, Government, public bodies and existing projects and we have been pleased to support their efforts. Scottish Enterprise will continue to engage with AREG as we increase Scotland’s use of renewable energy.
