This is what a buyer checks before they shortlist machinery and equipment suppliers.
What does a buyer check before evaluating a turbine?
They check output across the operating range rather than at the rated point, the efficiency at the load they will actually run, and the inlet conditions assumed. Then overhaul intervals, because availability over decades is what the investment case rests on.
A project developer is modelling twenty years of generation and needs figures that will survive a lender's technical review.

First, what the product is
The fields a buyer scans before deciding whether you are worth contacting. Missing one of them usually ends the visit without an email.
- 1
Turbine type and application
Steam, gas, hydro and wind are entirely different products.
- 2
Output range
The capacity band the machine covers.
- 3
Efficiency at rated and part load
Real operation is rarely at the rated point.
- 4
Inlet or resource conditions assumed
Performance figures are meaningless without them.
- 5
Operating envelope
Pressure, temperature or head range the machine tolerates.
- 6
Overhaul interval and expected life
The basis of the availability model.
- 7
Grid and control interface
Determines integration effort and compliance.
Then the paperwork
Naming the documents you can issue is what separates a supplier who can be audited from one who cannot.
| Document | What it proves | Where it belongs |
|---|---|---|
| Performance datasheetAsked at: feasibility and shortlisting | Output and efficiency across the operating range, with reference conditions | Publish it |
| Performance guarantee termsAsked at: contract stage — the core commercial document | What is guaranteed, under what conditions and with what remedy | Publish it |
| Type test or model test reportAsked at: technical due diligence | Verified performance of the design under a recognised method | Name it, share on request |
| Grid compliance certificationAsked at: interconnection approval | Conformity with the destination grid code | Name it, share on request |
| Maintenance and overhaul scheduleAsked at: availability modelling | Intervals, scope and expected outage duration | Publish it |
| Operating reference listAsked at: technical due diligence | Machines of the type running in comparable duty | Publish it |
| Spare parts and long-term support termsAsked at: investment case | Parts availability and support over the asset life | Publish it |
The shortlist moment
A buyer lines up a few suppliers and keeps the ones whose proof is easy to check. The rest get a closed tab, not an email.
The buyer asks: What does a buyer check before evaluating a turbine?
A few suppliers get compared side by side:
A supplier with Performance datasheet on the page
Output and efficiency across the operating range, with reference conditions
A supplier with Performance guarantee terms on the page
What is guaranteed, under what conditions and with what remedy
A supplier with Maintenance and overhaul schedule on the page
Intervals, scope and expected outage duration

Questions suppliers ask
How much performance data belongs in public?
Enough to model a project: output and efficiency across the range, with reference conditions stated. Developers build models before they contact suppliers, and a machine that cannot be modelled from public data is excluded before the conversation starts.
What does technical due diligence actually look for?
Evidence rather than specification. Type test results, an operating fleet in comparable duty, guarantee terms with real remedies, and a maintenance history. A lender's advisor is assessing whether the projected output is credible, not whether the machine is impressive.
How should long-term support be presented?
With commitments rather than intentions: parts availability period, service coverage, response times and what happens if the model is discontinued. An asset with a multi-decade life is bought partly on the supplier's willingness to be held to something.
Documents and standards named here are the ones buyers in this industry commonly ask for; requirements vary by market, customer and contract, so treat this as a starting checklist rather than a compliance list. Clearer pages can help discovery and evaluation. They do not guarantee rankings, AI citations, enquiries or revenue.
