Record project cancellations in the UK offshore wind industry highlight the impact of rising grid charges and market constraints, prompting calls for urgent reform to sustain the sector’s growth and decarbonisation targets.
The UK offshore wind sector saw a record number of project cancellations in 2023, according to Offshore Energies UK, as rising grid charges and harsher market conditions continued to reshape investment decisions. In its latest Offshore Wind Insight report, the Aberdeen-based trade body said the market had still shown “notable resilience”, but argued that the pace of deployment is now being constrained by a transmission charging system that is increasingly acting as an investment risk rather than a manageable operating cost.
The issue is especially acute for Scottish projects. Offshore wind farms in the north of Scotland face heavier transmission charges because they are farther from major centres of electricity demand, a cost burden that OEUK says is undermining the economic case for projects that can deliver high output. The report says those charges now need urgent reform, warning that the current structure fails to account for the wider system benefits of Scottish developments, including their higher capacity factors.
This has already fed through into project setbacks. Ocean Winds cancelled its Arven South scheme in March, while the backers of the West of Orkney offshore wind farm have said they will pause investment until there is a clearer route to market. According to OEUK, this is exactly the kind of delay that results when signals about transmission costs arrive too late in the process: projects are effectively worked up, then rendered uneconomic before final investment decisions can be taken.
The scale of the problem is underscored by a broader pattern of reversals across the industry. The Guardian reported in 2023 that the UK’s offshore wind auction that year failed to secure any new projects after the strike price was judged too low for a sector facing sharply higher costs. Other developers have been hit too, with Vattenfall halting work on its Norfolk Boreas project and Ørsted later cancelling major US offshore wind schemes as inflation, supply chain pressure and financing costs squeezed returns. For UK policymakers, the message from industry has been consistent: auction success on paper means little if projects cannot survive the journey to construction.
OEUK wants transmission charges to be fixed earlier, ideally at the contracts for difference stage, so that developers can price risk with greater certainty. It says any future system should align with the government’s strategic spatial energy plan, which is meant to map where generation, storage and grid assets should go, taking account of public views, environmental constraints and competing uses of land and sea.
The trade body is also pressing for stronger support for the domestic supply chain. It argues that offshore wind policy should do more to draw on the UK’s oil and gas industrial base, which it says already holds much of the engineering and project-delivery expertise needed for the next phase of expansion. Alongside targeted research and development support, faster permitting for demonstration projects and ring-fenced support for floating wind, OEUK says these measures would help drive down costs and improve the prospects for emerging technologies.
That matters because floating wind is central to longer-term UK decarbonisation plans, especially in deeper waters around Scotland. But OEUK says the sector will only scale if costs fall materially, with the aim of halving the levelised cost of floating wind by 2030.
There are still signs of momentum. The UK secured a record 8.4GW of offshore wind capacity in the seventh allocation round, a rare bright spot after the failures of 2023. Yet OEUK is urging ministers to maintain that pace, with another 7GW in the next round and at least 5GW a year from 2026 to 2030. Without that pipeline, it warns, Britain risks losing not just projects but the industrial capability that supports them.
Thibaut Cheret, OEUK’s wind and renewables manager, said offshore wind remains central to the UK’s clean energy plans, but added that targets alone will not deliver turbines, cables or grid connections. In his view, success now depends on cutting costs, backing the supply chain, upgrading networks faster and making sure the system rewards projects that can support the energy transition at scale.

- https://www.energyvoice.com/renewables-energy-transition/wind/596984/uk-offshore-wind-record-project-cancellations/ – In 2023, the UK experienced a record number of offshore wind project cancellations, as reported by Offshore Energies UK (OEUK). Despite these setbacks, the UK market demonstrated notable resilience. However, OEUK emphasized the need for urgent reform of transmission charges, particularly in Scotland, to support the scaling up of offshore wind projects. The current transmission charge structure fails to recognize the system-wide benefits provided by Scottish projects with higher capacity factors. OEUK proposed aligning transmission charges with the contracts for difference (CfDs) awarded by the government to deliver predictability and prevent project cancellations. Additionally, OEUK called for support for all forms of homegrown energy to assist the domestic supply chain in delivering offshore wind projects. The organization also advocated for targeted research and development grants, streamlined permitting for demonstration projects, and CfD ring-fencing for floating wind to achieve cost reductions in the emerging sector. Despite challenges, the UK managed to deliver a record-breaking allocation round, with 8.4GW of offshore wind capacity securing CfDs. OEUK urged the UK to continue this success by awarding another 7GW in the next allocation round and at least 5GW per year from 2026 to 2030 for subsequent rounds. The trade body emphasized the importance of building, connecting, and commissioning projects to achieve the UK’s clean energy goals and avoid falling behind globally.
- https://www.theguardian.com/environment/2023/sep/08/what-went-wrong-at-uk-governments-offshore-wind-auction – In September 2023, the UK government held an offshore wind auction aiming to secure new projects to meet its clean energy targets. However, the auction concluded without awarding any new offshore windfarms, a result described by industry sources as ‘catastrophic’. Despite the potential for 5 gigawatts of projects—enough to power 8 million homes annually—no new offshore windfarms were secured. This outcome was attributed to the auction price being set too low, considering the 40% increase in costs within the sector due to inflation across supply chains. The failure to secure new projects raised concerns about the UK’s ability to meet its green energy targets and deliver new jobs and lower energy bills.
- https://www.theguardian.com/environment/2023/nov/01/rsted-cancels-two-us-offshore-windfarm-projects-at-33bn-cost – In November 2023, Danish company Ørsted announced the cancellation of two major offshore windfarm projects in the US, resulting in a cost of over £3 billion. The decision was attributed to escalating costs in the global offshore wind industry, highlighting the financial challenges faced by developers in the sector. This move underscored the broader issues affecting offshore wind projects, including rising costs and supply chain disruptions, which have led to increased cancellations and delays in the industry.

The Ørsted-Phillips 66 partnership halted its Gigastack project, while ERM withdrew its Dolphyn project. Both projects aimed to produce hydrogen using electricity generated by offshore wind. The withdrawals were attributed to the need for securing alternative funding and the challenges in adapting to the current market conditions, highlighting the difficulties in financing innovative offshore wind projects in the UK.
- https://www.oeuk.org.uk/wp-content/uploads/2026/05/Offshore-Wind-Insight-2026-OEUK.pdf – The Offshore Wind Insight 2026 report by Offshore Energies UK (OEUK) highlights the challenges faced by the UK offshore wind sector, particularly concerning transmission charges. The report notes that transmission charges have evolved from a secondary operating cost into a material investment risk for Scottish wind projects. Forecasts indicate that by 2029, the contribution of Transmission Network Use of System (TNUoS) charges to the levelised cost of energy for a wind farm in northern Scotland could exceed £14/MWh. This increase is attributed to rising and volatile transmission charges, which are eroding project value, increasing strike prices, and slowing deployment. The report emphasizes the need for reform in transmission charging to support the UK’s clean power transition and prevent further project cancellations and delays.
