A Tidal Shift in Energy: Scotland Approves One of the World’s Largest Offshore Wind Farms
In a defining moment for Scotland’s renewable energy future, SSE Renewables has secured full planning consent and a marine licence for its monumental 4.1 GW Berwick Bank offshore wind farm. Approved by the Scottish Government in July 2025, the project marks a significant leap toward national energy security and net-zero targets. Located 38 km off the St Abbs coastline, this wind farm is poised to generate enough electricity to power every household in Scotland twice over—making it one of the most powerful offshore installations globally.

Consolidated Vision and Green Ambition
Berwick Bank didn’t start as a single project. Originally proposed as two separate developments—Berwick Bank and Marr Bank—the projects were merged into one large-scale vision, amplifying both scale and impact. With construction expected to begin by December 2026 and operations projected by December 2032, the project will feature up to 307 wind turbines and has already secured three grid connections: two in Branxton, East Lothian, and one in Blyth. This infrastructure groundwork lays a robust foundation for a seamless transition into commercial output. In parallel, aerial ornithology surveys spanning 25 months have been completed, signaling due diligence in protecting the region’s rich biodiversity.

Balancing Progress with Environmental Stewardship
While the sheer scale of Berwick Bank is a triumph for renewable energy, the project’s ecological sensitivity has not gone unnoticed. The area is a critical habitat for seabirds, prompting the Scottish Government to condition the project’s advancement on the development and approval of a comprehensive seabird compensation plan. This requirement ensures that the renewable push doesn’t come at nature’s cost. As Deputy First Minister Kate Forbes emphasized, the project demonstrates how Scotland can support energy goals while still honoring its commitment to conservation and sustainable development.

Engineering Excellence Meets Strategic Partnerships
Execution of such a massive offshore project demands best-in-class collaboration. SSE has already brought in Kent PLC for concept designs and Kidwell Energy to optimize inter-array cable layouts—illustrating the integration of expert knowledge at every stage. The onshore transmission infrastructure, already approved by East Lothian Council, sets the stage for smooth project rollout. As Berwick Bank progresses through its phases, it sets a benchmark not just in scale, but in project governance and environmental accountability.

With Scotland’s renewables sector gaining momentum through initiatives like ScotWind and INTOG, Berwick Bank stands as a testament to what’s possible when bold ambition meets rigorous planning. Want to dive deeper into the offshore wind boom or see how it impacts your region?
