25 years of British offshore wind

Since 2000, Britain's offshore wind sector has grown to 16,000 MW of capacity, providing 17% of the country's total generation in 2024 and employing approximately 40,000 people. The industry has evolved from the 4 MW Blyth wind farm to massive projects like Hornsea 2 (1.3 GW) and the under-construction Dogger Bank (3.6 GW). While the 'Contracts for Difference' (CfD) model has influenced global policy and provided price stability for consumers, the sector currently faces supply chain bottlenecks and inflation. Future growth depends on standardising turbine components, expanding national manufacturing in areas like blade technology and deep-water foundations, and leveraging new investments from Great British Energy.

• Offshore wind has become a major component of the UK energy mix, accounting for 17% of total generation in 2024 and producing enough power for over 16 million homes annually.
• The sector has driven significant employment and industrial growth, with 40,000 people currently employed in offshore wind, including 7,000 jobs added in the last two years, supported by over 2,000 supply chain companies.
• The scale of installations has increased dramatically from the 4 MW Blyth wind farm in 2000 to Hornsea 2, the world's largest at 1.3 GW, and the upcoming Dogger Bank project with a total capacity of 3.6 GW.
• Britain's 'Contracts for Difference' (CfD) support scheme, implemented in 2014, has been adopted by 13 other countries and helped save typical customers an average of £18 during the 2022/2023 winter gas price spike.
• The industry faces critical challenges including supply chain bottlenecks, financing pressures, and inflation, with new-build gas turbines reportedly costing three times more than three years ago.
• To ensure long-term health, the sector requires standardisation of component sizes and deployment schedules, as frequent turbine size increases can stifle innovation and complicate logistics.
• The UK government is investing in national manufacturing and infrastructure, including £55 million for the Cromarty Firth port and £1 billion allocated to Great British Energy for clean energy supply chains.
