Wind Turbine RFQ & Equipment Procurement Guide
A useful request for quotation connects the project requirement to an identifiable equipment package. Prepare the information that lets suppliers compare the same scope and explain what remains to be confirmed.
A clear scope makes quotations comparable.
Connect the project requirement to equipment identities, interfaces and documents.
01 / Project brief
State the requirement before requesting a price.
Provide the destination country, site coordinates, available wind information and electricity requirement.
Provide the destination country, site coordinates, available wind information and electricity requirement. Identify the intended grid or independent-supply arrangement and the target project schedule.
If you have a model shortlist, include it with the reasons for comparison. Otherwise state the requirement you want reviewed. The turbine selection guide helps turn site and load information into an equipment discussion.
02 / Scope list
Name every item to be supplied or reviewed.
Create a list covering turbine assemblies, controllers, converters, tower arrangements and the documents needed by the project.
Create a list covering turbine assemblies, controllers, converters, tower arrangements and the documents needed by the project. State quantities and identify existing third-party equipment that the new package must interface with.
MARSTON can discuss separate supply of turbine assemblies, controllers and conversion equipment, with tower-supplier coordination where required. The quotation establishes the actual package; it should not be assumed to include all local works or third-party devices.
03 / Technical evidence
Request documents for the quoted configuration.
Identify the model-specific specification, connection information, interface drawings and instructions needed for your review.
Identify the model-specific specification, connection information, interface drawings and instructions needed for your review. Ask which documents can be supplied and which revision will accompany the equipment.
For performance claims, use the power-curve guide to check configuration and measurement boundaries. Request project-relevant certification evidence when required, without assuming that a general brochure proves every requirement.
04 / Delivery & local work
Describe project responsibilities beyond the equipment.
State the delivery location and discuss transport, packaging and document requirements with the responsible parties.
State the delivery location and discuss transport, packaging and document requirements with the responsible parties. Identify who is arranging unloading, installation access and local project work.
List foundations, tower erection, cabling, local design and connection approvals under the party responsible for each. Obtain destination-specific import and project requirements from the relevant professionals and retain them with the procurement information.
05 / Proposal comparison
Use the same boundaries when comparing prices.
Compare the equipment identities, supplied documents, service scope and project exclusions before comparing totals.
Compare the equipment identities, supplied documents, service scope and project exclusions before comparing totals. Record the interfaces and assumptions on which each proposal depends.
Clarify warranty terms, spares, service access and support responsibilities in the commercial and technical proposal. If one offer excludes a controller, tower or installation item, identify that difference explicitly rather than treating the prices as equivalent packages.
06 / RFQ record
Keep questions and changes traceable.
Maintain a dated list of requirements, supplier responses and unresolved items.
Maintain a dated list of requirements, supplier responses and unresolved items. Keep revisions of the model shortlist, interface information and scope list so later changes can be assessed against the agreed proposal.
Submit the available project pack through Request a Quote. Mark unavailable information and state which technical comparison you need. A complete record supports engineering communication; it does not replace a signed supply agreement.

| Equipment list | Models, quantities, interfaces and scope | Identify supplied items. |
| Document request | Specification, drawings and applicable evidence | Support technical review. |
| Delivery & works | Destination, logistics and local responsibilities | Define project boundaries. |
| Open items | Questions, assumptions and revisions | Track the proposal process. |
Engineering questions.
Is this page the quotation form?
This guide prepares the information. Use Request a Quote to submit the enquiry and discuss the proposed package.
Can I request only the turbine assembly?
MARSTON can discuss separate turbine supply. Confirm the control, conversion and interface information needed for the project.
Are all requested technical documents automatically included?
Document availability and the supplied scope must be agreed for the quoted configuration.
Does the quoted price include local installation?
The proposal should identify included work and exclusions. Local works must be assigned to the responsible party.
What should I do if wind data are missing?
State what is available and what is unknown. Use the site assessment guide to establish the information needed for further review.
How should certification requirements be handled?
Identify the destination and project requirements and request applicable evidence for the actual equipment; do not assume universal approval.
