UK Offshore Wind Sabotage Rated Credible Risk as Chinese Component Dependency Deepens
An analyst told Montel sabotage of European wind farms is plausible, with a third of UK offshore capacity linked to China and near-total dependency on Chinese turbine components.
Sabotage of UK and European offshore wind assets is a "credible scenario," an analyst told Montel in the week of 2026-08-31, following a report in The Times estimating that roughly a third of UK offshore wind farm capacity is linked to China.6
The exposure is structural. Henning Gloystein, managing director at consultancy Eurasia Group, told Montel the UK and EU have a near-total dependency on China for key components used in turbines — a dependency that runs through the bearings, magnets and embedded chips that govern critical functions inside operating assets, not just the visible hardware.6
The concern has two distinct forms. One is surveillance: Chinese offshore-wind equipment could be used to monitor European naval operations in the North Sea and Baltic. The other is disruption — China could deactivate wind farms to destabilise the grid, potentially through remote software updates or chips embedded in turbine control systems, The Economist reported in May (2026-05-17).2
Chinese turbine manufacturers have expanded into export markets fast enough that the theoretical exposure is becoming a practical one. Endri Lico of Wood Mackenzie estimated that Chinese turbine makers captured around 18% of the global market outside China in 2025, triple their share in 2024.2
The UK government moved on at least one front. It blocked Ming Yang's plans to build a £1.5 billion turbine factory in Scotland at the port of Ardersier, citing national security. The decision killed up to 1,500 jobs attached to the project and left the Chinese manufacturer looking elsewhere.3
Ming Yang has since joined Norwegian Offshore Wind, Norway's largest offshore wind industry cluster, Energy Voice reported on Thursday (2026-05-28). Norway has set a 30 GW offshore wind target by 2040 with a focus on floating wind — a technology segment where Chinese manufacturers have invested heavily. The company holds a global installed base of more than 25,000 turbines representing over 155 GW of capacity and reported annual revenue of approximately EUR 4.5 billion in 2025.3
Blocking one factory has not closed existing supply lines. At Ardersier itself, port owner Haventus signed a memorandum of understanding with China's Dajin — a manufacturer of foundations and operator of specialist transport vessels — to explore joint offshore wind work across the UK and European market, Energy Voice reported on Friday (2026-08-21).5
The solar sector drew the same warning months earlier. An analyst told the Solar 2026 seminar in Helsinki on Tuesday (2026-05-19) that European reliance on Chinese-made solar components leaves the bloc vulnerable to attacks on its energy system, Montel reported. The offshore wind case is harder to remediate. A compromised inverter in a solar park can be swapped in days; a turbine with embedded Chinese firmware installed on a North Sea platform cannot.1
The precedent for infrastructure sabotage in European waters is recent. In October 2023, the Balticconnector pipeline between Finland and Estonia was shut down amid an international investigation into suspected sabotage, less than a year after the Nord Stream explosions. Offshore wind turbines sitting in the same waters carry no comparable physical protection and a far more complex internal architecture.4
ICE Endex TTF front-month gas gained 3.41% to €75.83/MWh on Tuesday (2026-09-08). Any sustained disruption to European wind generation — from weather, technical failure or deliberate interference — feeds through to gas demand inside the same trading session. A wind fleet carrying embedded vulnerabilities sits inside that pricing dynamic whether markets price the risk explicitly or not.
The question governments have not publicly answered is what inspection regime can reliably detect firmware-level threats in turbine components before they are activated. Regulators have not set a public standard for that, and the Ardersier-Dajin MoU signals that Chinese firms still expect to remain inside the UK supply chain regardless of the security debate running around them.
