As the UK government plans for an additional 100GW of wind capacity in the North Sea, the availability and pricing of turbines have become critical issues. Households and businesses continue to face significant pressure from high energy costs, making it increasingly difficult to justify limiting developers to just two or three turbine suppliers when cheaper and more advanced options are readily available on the global market.
The High Cost of a Narrow Supplier Base
This restricted supplier base is pushing project costs up by 20 to 30 per cent, while also limiting access to cutting-edge technology. During Prime Minister Keir Starmer's recent three-day visit to China, the rapid advancements of Chinese manufacturers were on full display. Between 2021 and 2025, Chinese turbine makers introduced an impressive 426 new models, compared to just 29 from non-Chinese firms. Yet, UK developers currently have access to only a small fraction of this fast-expanding global market.
Competition Over Protectionism
This issue is not about choosing China over Europe; it is fundamentally about fostering competition. A market dominated by a handful of incumbents inevitably leads to higher expenses, with the financial burden ultimately landing on households. If the UK aims to achieve cheaper clean power, it must embrace more supply, expand manufacturing capacity, and provide greater choice for developers.
Addressing Cybersecurity Concerns Pragmatically
While cybersecurity and risk mitigation must be taken seriously, the current approach often uses these concerns as a veto, preventing cheaper energy and faster deployment, rather than treating them as manageable risks to be solved. A more effective strategy would involve setting rigorous standards, establishing a tough testing regime, requiring independent assurance, and ensuring ongoing monitoring.
By backing British cybersecurity expertise, the UK can ensure that turbines operating within its borders are safe and secure. An approach that pairs Chinese turbine hardware with UK-developed and government-approved security solutions would not only enhance safety but also create new economic opportunities and jobs. Tech developers, such as Octopus Energy, are prepared to contribute to this effort and play a vital role in bolstering the UK's energy security.
Perspective on Supply Chains
It is essential to maintain a sense of perspective regarding supply chains. There is no such thing as a purely "European" turbine; only European-assembled turbines exist. Many turbines already deployed across the UK contain components manufactured in China. Therefore, the question is not whether Chinese-made parts are present in the system—they already are—but whether the UK has the right standards and oversight across the entire supply chain.
This logic is already accepted in everyday life. Anyone using an iPhone or AirPods is carrying products made in China, and homes are filled with electronic items like TVs and laptops manufactured there. While turbines are more sensitive, justifying higher security standards, the same common-sense principle of risk mitigation should apply, rather than resorting to outright bans.
Economic Opportunities and Job Creation
A larger wind industry represents an enormous opportunity for the UK economy and job market. One Chinese manufacturer has already expressed interest in opening a plant in Scotland, which could create up to 1,500 jobs. Requiring overseas manufacturers to support the UK economy is a smart strategy to maximise the natural wind resources available.
Today, nearly 2,000 companies across the UK are part of the wind supply chain, including 160 factories. These entities are expected to contribute £18.2 billion over the next decade. By stopping market restrictions, the UK can further grow this sector and reduce energy bills for consumers.
From Ambition to Reality
While the latest offshore wind auction round, AR7, awarded a record 8.4GW, signalling strong ambition, these awards must still be converted into real projects at prices consumers can afford. If turbine costs remain inflated and supply constrained, impressive pipeline numbers on paper could lead to delays, renegotiations, or cancellations in practice.
A Path Forward for Cheaper Clean Power
The UK needs more competition in turbine supply, expanded manufacturing capacity, and clear, enforceable security standards. The government supports these objectives, and this week could mark a practical step forward. By opening up the UK wind market to more suppliers, alongside robust, UK-approved cybersecurity arrangements, the nation can unlock cheaper clean power swiftly and with confidence.
