How the estimates were built: data sources, modelling approach and validation steps.
Research approach
A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.
The size is built upward from installed and commissioned capacity by project, turbine count per site, and the realised price per megawatt for each cost block: turbine supply, foundations, electrical infrastructure, installation and long-term service. Capacity additions come from auction awards, final investment decisions and construction schedules; prices come from contract values, vessel and cable day rates and disclosed order books. The build is then checked against disclosed revenue of turbine makers, cable suppliers, marine contractors and project owners, adjusted for the share of each company's revenue that is offshore. The top-down comparison is a check on the build, not a second estimate averaged in. Where the two disagree, the unit or price assumption in the bottom-up build is corrected.
The four stages
The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.
What the build rests on, and what checks it
The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.
- Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
- Realised pricing by tier and channel, rather than one blended average applied across the whole market
- Take-up and frequency: how much of the addressable base buys, and how often it repeats
- Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
- Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
- Trade and customs flows, where the product crosses borders in a separately recorded form
Data sources
Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.
- Commercial and product leadership at the companies that supply the market
- Procurement and specification leads at the organisations that buy it
- Distributors, integrators and channel partners, where the market is served indirectly
- Regulatory and standards specialists, where approval governs what can be sold at all
- Company filings, annual reports and investor disclosure
- Government statistics, customs records and regulatory registers
- Trade association output and standards-body publications
- Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Interviews target the commercial and technical roles that decide offshore wind spending: project development and procurement heads at utilities and independent producers, sales and supply-chain leads at turbine, cable and foundation manufacturers, installation vessel and port operators, grid and transmission planners, and the lenders and advisers who finance projects. Regulatory and auction-design specialists are included to test permitting timelines and award assumptions. Sampling emphasises Europe, where the installed base and tender pipeline are deepest, and China, where volumes and local supply chains differ most from the rest of the market. Taiwan, South Korea, Japan and the United States are covered to test the emerging regions.
Desk research rests on national auction and tender results published by the UK Contracts for Difference scheme, the German Federal Network Agency, the Netherlands Enterprise Agency and the Danish Energy Agency, together with seabed lease records from the Crown Estate and the US Bureau of Ocean Energy Management. Installed capacity comes from the International Renewable Energy Agency and the Global Wind Energy Council. Trade flows are checked against customs code 8502.31 for wind-powered generating sets and 8544.60 for high-voltage cable. Company annual reports, stock exchange filings and order announcements supply revenue and backlog, and European network operators' ten-year development plans supply grid connection schedules.
Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.
Forecasting
The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.
The forecast is built from the auction and lease pipeline, converted to commissioning dates with a delay allowance, and priced using expected turbine, foundation and cable costs. Demand rises as national capacity targets are met through scheduled auctions, larger turbines lower cost per megawatt, and floating projects reach commercial scale. Prices are held near current levels in real terms after the recent cost inflation is normalised. For the forecast to hold, auctions must be awarded on schedule with indexed or reset strike prices, installation vessels and cable capacity must expand in line with awards, and grid connections must be delivered within the permitting windows now assumed.
Triangulation and validation
No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.
Outputs were back-tested by running the same method on 2020 to 2024 and comparing the result with recorded growth in installed capacity and reported supplier revenue. Segment shifts, such as the move toward larger turbines, floating foundations and HVDC links, were reviewed with industry experts against known project awards. Sensitivities tested included a twelve-month delay in awarded projects, a change of ten percent in turbine and cable unit prices, and a lower share of awarded capacity reaching construction. Regional totals were reconciled to the global figure, and each segmentation axis was checked to sum to the market in the base year and the final forecast year.
Confidence and limitations
Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.
The estimate is firmest for Europe and China, where project registers, auction results and supplier disclosures are public, and for the turbine, foundation and cable segments that follow from them. It is thinner for installation and logistics pricing, where day rates are negotiated privately, and for floating wind, green hydrogen and platform electrification, where few projects have reached final investment decision. The base year carries a band of plus or minus fifteen percent, wider for later years. Structural risks that would force a revision include auction cancellations, sustained increases in financing cost, trade restrictions on turbine imports and grid delays.
