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 was built upward for each technology and application from installed or shipped energy and power capacity, the share of annual additions that each technology and project type represents, and the realised price per unit of delivered capacity, including power conversion, software and balance of plant. Prices were taken from tender results, utility procurement filings and manufacturer disclosures, then adjusted for project size and region. The build was then compared against revenue disclosed by the named suppliers and against regional additions reported by system operators. That comparison is a check and is not averaged into the figure. Where the two disagreed, the volume or price assumption in the bottom-up build was the thing 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 people who decide and price storage projects: procurement and planning leads at utilities and system operators, development and finance heads at independent power producers, sales and project directors at battery and system suppliers, engineering and construction contractors, and market-rules specialists. Sampling emphasises the regions that account for most additions, namely China, the United States, Europe and Australia, with smaller coverage of Chile, India and the Gulf states. Conversations test installed prices, project pipelines, delivery lead times, warranty terms and how revenue is stacked across market products, and they are used to challenge the volume and price inputs in the build.
Desk research rests on interconnection queue data published by the Federal Energy Regulatory Commission and regional transmission operators, Australian Energy Market Operator reports, the U.S. Energy Information Administration generator inventory, China Energy Storage Alliance statistics, and International Energy Agency and IRENA capacity data. Pricing draws on public auction and capacity market results, utility integrated resource plans, and customs trade data for lithium-ion cells under tariff heading 8507. Company annual reports and investor presentations supply segment revenue and order backlog.
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 extends capacity additions by region from announced procurement targets, capacity market schedules and the pipeline of projects with secured interconnection, then applies a declining price path for battery systems and a changing technology mix. Demand shifts assumed include rising solar penetration, retirement of fossil plants and growth in electricity load from data centres. For the forecast to hold, interconnection queues must clear at a pace close to recent experience, cell prices must not rebound sharply, and ancillary service markets must not saturate faster than longer-duration products open. The very fast recent growth is treated partly as a base effect and is allowed to slow.
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.
The outputs were back-tested against recorded installed capacity and price history for the historical years, and the implied growth of each segment was compared with the growth of the market as a whole to catch segments that outrun it without a cause. Technology and regional shifts were reviewed with sector specialists, and the sensitivities tested covered cell price, interconnection delay, tariff changes and a slower rise in long-duration adoption. Segment totals were reconciled to the scope total in every year, and regional totals to the global figure.
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 lithium-ion systems in China, the United States, Europe and Australia, where procurement, interconnection and company filings are public. It is weaker for sodium-based, flow, hydrogen and gravity storage, where few projects are commercial and prices are reported unevenly, and for emerging regions with limited disclosure. The published range for this market is wide, and the estimate sits near its middle. A revision would be forced by a sharp change in tariffs on cells, a rapid fall in ancillary prices, or restrictions on connecting new storage to the grid. A reasonable band is plus or minus fifteen percent.
