Offshore Wind's Bottleneck Is Machines

Offshore wind in Britain no longer waits on money. It waits on machines.

On 11 November 2026, RWE and KKR reached financial close on Vanguard West and Vanguard East. A consortium of 35 international banks is providing cash facilities of £11.1 billion and ancillary facilities of £1.7 billion. RWE's release headlines the deal as the "Largest ever non-recourse project financing for UK offshore wind." The total investment is around £12 billion, counting both the wind farms and their transmission infrastructure. Capital markets, in other words, have said yes at scale.

The same day, the company supplying turbines to part of that project reported a quarter that disappointed. The scarce input in European offshore wind is now the delivery of working turbines on schedule, not the cheque.

The money is done

RWE says KKR holds 50% of each project, a 50:50 joint venture with RWE leading delivery. The two farms have a combined capacity of around 2.8 gigawatts and will be fully commissioned in 2030. Markus Krebber, RWE's chief executive, said the financing "demonstrates our lenders' trust in these projects and our ability to deliver them."

Tgs4c's Jordan May called the financial close the "first Allocation Round 7 project to make FID." Tgs4c's May also said the UK has 10.5 GW under construction and that another 2.76 GW will keep UK waters busy. The deal also shows, Tgs4c's May said, "industry resilience to global geopolitical events which challenge the global investment environment."

Financing looks settled for projects that clear the bar. Delivery is where the risk has gone.

One blade, one quarter

Vestas, the world's biggest turbine maker outside China, posted earnings before interest, tax and special items of €483 million ($539 million) for the third quarter, against a €526 million forecast in a company-compiled analyst poll, Reuters reported via Baird Maritime. The shares dropped sharply before partially recovering, trading 4.2 per cent lower at 11:07 GMT on 11 November.

The culprit was physical. A huge blade broke in July at EnBW's He Dreiht wind farm in Germany. Vestas CEO Henrik Andersen told investors, "That's not for free, that has quite a large operating cost," and declined to elaborate. Investing.com's earnings-call write-up shows warranty costs of EUR 181 million in the quarter, with the company absorbing the He Dreiht costs. Adjusted free cash flow was EUR 99 million, lower than a year earlier because of working capital tied to offshore growth.

Guidance narrowed. Vestas now sees an adjusted operating margin of 7.5 per cent to 8.5 per cent and sales of €20.5 billion to €21.5 billion, tighter than the €20 billion-€22 billion sales range it had given before. JPMorgan analysts, who rate the stock "overweight", said the narrower range implied a trim to full-year profit expectations, according to Reuters.

Vestas also holds the contract for Vanguard West: 92 V236-15.0 MW turbines, according to RWE's 20 February 2026 release. One supplier's quality problem is therefore a live variable in a project that lenders have just priced.

The pipeline behind it

The next big UK project shows the same shape. On 11 November, SSE named Siemens Energy preferred supplier of turbines and substation platforms for Berwick Bank B. That is a selection, not a commitment. SSE says the appointment remains subject to a final investment decision and a final contract award, and its own FAQ answers whether construction is confirmed with "Not yet." It expects a decision late next year.

The timeline is long. Subject to that decision, preparatory offshore construction could begin in 2028, with turbine and substation installation starting in 2030 and finishing in 2032. SSE says the appointment supports 2,677 skilled roles, including blade manufacturing in Hull. Berwick Bank B is part of a wider project that SSE chief executive Martin Pibworth says "Berwick Bank has the potential to become the world's largest offshore wind farm." The supply chain is being asked to reserve capacity years ahead of any decision to build.

The case against

The obvious objection is that Vestas had a good quarter by most measures. Revenue reached EUR 5.7 billion, up 6%, and the EBIT margin was 8.5%, up from 7.8% a year earlier. Earnings per share hit an "all-time high" of EUR 1.14, up 21%, and the combined order backlog reached EUR 78 billion, which Andersen called the highest in the company's history. Vestas says its root-cause analysis found no design issue and that no further negative cost impact is expected in 2027. CFO Jakob Wegge-Larsen called the broken blade an isolated incident.

All true, and none of it rescues the argument that money is the constraint. A backlog that size is a queue, and a queue is what scarce delivery capacity looks like. Vestas says offshore should return to profitability in 2027, helped by better takt times, installation cadence and manufacturing efficiency. That is a promise to fix the machinery of delivery, not a sign that it already runs smoothly. Andersen himself called offshore the biggest lever toward the company's long-term 10% EBIT margin target.

Wegge-Larsen also cautioned against reading the 27 per cent drop in Q3 order bookings as a weaker US onshore market, since bookings swing in the short term. The same caution applies here. One quarter is not a trend. But a company with strong earnings per share still lost a chunk of its market value in a morning over one component, and that tells you where the market now sees the risk.

What follows

If this read is right, the competitive edge in European offshore wind shifts from whoever raises capital cheapest to whoever secures slots, vessels, blades and quality control. Developers with turbine contracts locked in, such as RWE on Vanguard, will look better than those still at preferred-supplier stage. Suppliers will win on reliability as much as on price.

RWE's own numbers suggest it is ready to carry that weight. It reports €10.7 billion of net investment so far in 2026 and 13.5 GW under construction. Krebber says preparatory works are "well advanced" ahead of offshore construction in early 2027.

The banks have signed. Now somebody has to keep the blades on.
