The Scottish Government has granted consent for the 4.1 GW Berwick Bank offshore wind farm, paving the way for what is expected to become the world’s largest offshore wind installation. Developed by SSE Renewables, the project has received both marine licences and a Section 36 consent order, marking the conclusion of more than a decade of planning and assessment.
Situated approximately 38 kilometres off the coast of East Lothian, in the outer Firth of Forth near St Abb’s Head, the site is considered a prime location for large-scale renewable generation due to its favourable wind conditions and proximity to existing grid infrastructure. Once operational, Berwick Bank could produce up to 11.2 terawatt hours of electricity each year, equivalent to meeting the needs of 17 percent of UK households or powering all Scottish homes twice over.
The approval positions Berwick Bank as a flagship project in both Scotland’s and the UK’s transition to net zero. With the UK government aiming to deliver between 43 and 50 GW of offshore wind capacity by 2030, and Scotland committed to achieving net zero emissions by 2045, the project will contribute significantly to these national targets.
Decarbonisation and energy security in focus
Offshore wind is increasingly seen as a cornerstone of UK energy policy, offering a low-carbon alternative to fossil fuel generation and helping to reduce exposure to volatile global gas markets. The scale of Berwick Bank means it could play a meaningful role in improving energy resilience.
By generating electricity at this capacity, the wind farm would not only help cut greenhouse gas emissions but also provide a reliable domestic power source, reducing dependence on imported energy. This aligns with the UK’s Clean Power 2030 strategy, which aims to decarbonise the electricity grid while supporting sustainable economic growth.
Industry analysts note that the timing of the consent is significant, as large-scale renewable projects are increasingly viewed as vital for meeting both environmental goals and the need for affordable, secure energy supplies.
Economic impact and community benefits
The project is expected to deliver substantial economic benefits during both construction and operation. SSE Renewables estimates that Berwick Bank could support around 9 300 jobs across the UK, with roughly half of those in Scotland. These roles will span direct employment in construction and operations, as well as indirect opportunities across the wider supply chain.
Over its lifetime, the project is forecast to generate between £8 billion and £8.3 billion in economic value for the UK. Local economies are set to benefit from contracts for manufacturing, assembly, and ongoing maintenance. Ports and fabrication yards in Scotland are likely to play a central role in delivering the components for the turbines, foundations, and subsea infrastructure.
The scale of the investment and the expected long-term operational presence mean Berwick Bank could become a cornerstone of Scotland’s renewable energy sector, fostering skills development and supporting local businesses for decades.
Environmental concerns and safeguards
While the project has secured government approval, it comes with environmental conditions. Chief among these is a requirement for a detailed seabird compensation plan. Environmental organisations, including RSPB Scotland, have raised concerns about potential impacts on protected seabird populations, which inhabit and migrate through the area.
The Scottish Government has stipulated that the developer must outline and implement measures to mitigate these effects before construction begins. This could involve habitat restoration, population monitoring, and other targeted interventions.
SSE Renewables has stated that it will work closely with conservation bodies to ensure that the project is delivered in a way that safeguards biodiversity while contributing to climate objectives.
Next steps towards final investment
With planning consent now in place, the next milestone for Berwick Bank will be securing a Contract for Difference, the UK’s primary mechanism for supporting low-carbon power generation. This will provide revenue certainty for the project, enabling the developer to proceed to a final investment decision.
Once financial arrangements are secured, construction could begin within the decade, although exact timelines will depend on supply chain readiness and grid connection agreements. When completed, Berwick Bank will be the largest offshore wind farm in the world.
