Offshore Wind and Energy Security: Why Governments Are Raising Concerns
Governments are increasingly scrutinising offshore wind projects over national security concerns, as energy systems become more complex and digitally connected.
The UK government has ruled out the use of Mingyang turbines in offshore wind projects following months of review. The decision came after the company was linked to a proposed supply deal for the Green Volt floating wind project off the coast of Scotland, with officials citing risks linked to critical infrastructure.
This reflects a wider trend. In the United States, several offshore wind projects have faced delays and temporary pauses following warnings about potential interference with military radar systems, alongside broader energy security concerns.
Modern offshore wind farms are highly digital, relying on software, sensors, and remote monitoring to operate efficiently. This raises questions not just about performance, but about who has access to data and control systems. At the same time, much of the global supply chain for turbines and components is concentrated overseas—particularly in China—creating potential vulnerabilities if geopolitical tensions disrupt access to key technologies.
Governments are also paying closer attention to cybersecurity and system resilience, as energy infrastructure becomes more integrated into national power grids. This includes risks such as unauthorised access, disruption to operations, and the long-term reliability of systems that underpin electricity supply.
Taken together, these developments point to a clear shift. Offshore wind is no longer just about clean energy—it is increasingly being treated as critical infrastructure, where security, supply chains, and control are as important as generation itself.
