Crown Estate Approves 4.7 GW Offshore Wind Expansion, Boosting UK Energy Goals

On May 9, 2025, The Crown Estate approved a 4.7 gigawatt (GW) expansion of offshore wind capacity through its Capacity Increase Programme, marking a significant advancement toward the United Kingdom's goal of achieving 50 GW of offshore wind energy by 2030. This initiative encompasses seven projects, including RWE's Rampion 2 and SSE and Equinor's Dogger Bank D, all situated within existing offshore wind sites with established grid connections and infrastructure.

The UK's current offshore wind capacity stands at approximately 15 GW. The planned expansion is expected to provide clean energy to up to four million homes, reducing reliance on fossil fuels and enhancing energy security. Gus Jaspert, Managing Director of Marine at The Crown Estate, emphasized the economic benefits of offshore wind, stating that it supports national prosperity by creating jobs and supporting supply chains.

Despite these advancements, the offshore wind sector faces several challenges. Rising construction costs and supply chain issues have led to project delays and cancellations. For instance, Ørsted recently halted its Hornsea 4 project, citing increased costs and operational risks. The company projected losses between £399 million and £513 million due to this suspension. Additionally, developers encounter significant delays in securing grid connections, with some projects facing waiting times of up to 15 years, potentially impacting the timely achievement of the 50 GW target by 2030.

In response to these challenges, the UK government has increased funding for offshore wind projects. The 'Clean Industry Bonus' scheme has been expanded from £200 million to £544 million ($721.78 million) to support projects in the upcoming renewable subsidy auction. This funding aims to stimulate private investment in domestic manufacturing for the offshore wind industry. Furthermore, the government is considering reforms to expedite the development of wind farms and related infrastructure, including proposals to reduce community rights to challenge large clean-power projects.

The Crown Estate's approval of the 4.7 GW expansion represents a significant step toward the UK's renewable energy goals. However, addressing economic and logistical challenges is essential to fully realize the potential of offshore wind expansion and meet the nation's decarbonization objectives.
