Scotland’s offshore wind sector faces a critical moment as growing policy uncertainty threatens investor confidence and stalls major projects, the chief executive of Scottish Renewables has warned. The future of a sector that promises vast economic and environmental benefits now hangs in the balance amid delays and unclear government direction.
Speaking at the All-Energy conference in Glasgow, Claire Mack laid bare the precarious position of the industry, urging swift action to secure the investment and policy clarity needed to keep Scotland’s offshore wind ambitions afloat.
A Watershed Moment for Scottish Offshore Wind
Claire Mack didn’t mince words. “Scotland’s offshore wind potential clearly offers significant benefits for our economy and energy security,” she said. Yet, despite the sector’s promise, she warned the UK government risks missing its clean power targets if Scottish offshore projects don’t get the green light soon.
The industry faces what Mack called a “watershed moment,” with green shoots of progress visible but vulnerable. To push ahead, the sector needs a sustainable policy framework that provides private investors with certainty — no small ask given current doubts swirling around auctions, grid infrastructure, and electricity market reforms.
The stakes are huge. Offshore wind isn’t just about clean energy. It supports jobs, local supply chains, and could even ease household energy bills. But without clear, immediate government action on auction parameters and transmission charging reforms, developers risk losing momentum at a crucial stage.
Scotland’s Offshore Wind Pipeline: Ambitious But At Risk
Scotland is no small player in offshore wind. The country boasts a pipeline exceeding 40GW in capacity, with:
-
5 projects already consented
-
8 in various planning stages
-
22 more under development
This puts Scotland comfortably in the global top ten offshore wind markets, poised for a decade of growth—if the policy environment cooperates.
Recent reports estimate Scotland’s offshore wind pipeline could unlock between £29 billion and £35 billion in public value over the next 40 years. That’s a staggering figure, underlining just how much is riding on these projects.
The Highlands and Islands region alone could attract around £75 billion out of £100 billion total investment potential by 2040, largely driven by renewables.
Yet, the excitement is tempered by growing concerns over current market reforms. In particular, uncertainty around zonal pricing and volatile transmission charges—known as Transmission Network Use of System (TNUoS) charges—are casting a long shadow.
Here’s the kicker: reforms could save consumers an estimated £16.2 billion between 2028 and 2050. But if zonal pricing goes ahead without changes, a projected £8.9 billion benefit could flip into a £9.6 billion cost. That’s a huge swing, and it has investors jittery.
Industry’s Call for Government to Step Up
Mack called on both the Scottish and UK governments to pick up the pace. She emphasized that efficient consenting processes and new grid infrastructure are vital if Scotland is to realize its offshore wind potential.
The message is clear: “Offshore wind is good for jobs, supply chains and has the potential to make household bills more affordable, so both governments should put their shoulder to the wheel on creating the best possible environment.”
Without these efforts, there’s a real risk that promising projects will stall or be shelved altogether. Recent news that Orsted has paused development of its Hornsea 4 Offshore Wind Farm in England adds fuel to concerns that the UK’s offshore wind ambitions are losing steam.
What’s Next: CfD Allocation Round 7 and Auction Pressures
The UK Government is poised to open the Contracts for Difference (CfD) Allocation Round 7, a critical funding mechanism for renewables.
Auction parameters for this round remain unclear, and developers are calling for immediate certainty. Delays or unfavorable terms could make or break investment decisions due soon.
Developers are also seeking reforms to transmission charging arrangements that will make the market more stable and attractive to investors.
The table below sums up some key figures illustrating the economic impact of reforms versus current uncertainty:
| Factor | Potential Benefit (£bn) | Potential Cost (£bn) |
|---|---|---|
| Public value from offshore wind pipeline | 29 – 35 | – |
| Total investment potential in Highlands | 75 (out of 100) | – |
| Consumer savings from TNUoS reforms | 16.2 | – |
| Potential consumer cost from zonal pricing | – | 9.6 |
This delicate balance between policy and investment could determine whether Scotland remains a global offshore wind leader or falls behind as uncertainty breeds caution.
