A 1500kW used diesel generator is usually bought for a site where downtime is expensive: mining camps, factories, data centers, large commercial buildings, utility backup sites, and industrial projects with heavy motors or continuous process loads. At this power range, the buying decision should not start with a price list alone. The useful question is whether the available unit matches the load, duty, frequency, voltage, condition, transport route, and proof file requirements.
For export buyers, especially buyers sourcing from stock, a 1500kW RFQ needs more detail than a small standby generator request. A few missing details can change the quotation, the inspection work, the packing plan, and the shipping cost. Before asking for a final price, buyers should prepare the following checks.
Start with duty: standby, prime, or continuous load
The word “1500kW” is not enough. A generator sold for standby service may not be the right match for a site that expects long daily running hours. Before requesting a quote, confirm whether the unit will support emergency standby, prime power, or continuous industrial work.
- For standby use, clarify the critical load and expected outage duration.
- For prime use, confirm daily running hours, fuel arrangement, cooling conditions, and load variation.
- For industrial sites with motors, compressors, pumps, crushers, or elevators, send starting current and load sequence if available.
This is the same reason buyers should not compare a 1500kW unit only by engine brand. Load behavior can affect the recommended engine, alternator, control system, switchgear, and whether one large unit or parallel smaller units makes more sense.
Confirm frequency, voltage, and site standard early
For used generator exports, frequency and voltage are often the first technical filter. A buyer in a 50Hz market should not assume every available 1500kW stock unit can be used directly. A buyer in a 60Hz market should make the same check before reserving stock.
Send the destination country, frequency, output voltage, phase, and whether the unit will connect to an existing switchboard. If the site requires synchronization, ATS, transformer matching, or local code documentation, that should be mentioned before the supplier prepares a CIF quote.

Ask for the condition file, not only the model name
At this power level, two units with the same model name can be very different purchases. The useful documents are the condition photos, engine and alternator nameplates, running-hour information where available, controller photos, service notes, and inspection records. A serious supplier should be able to explain what has been checked and what still needs buyer confirmation.
Buyers should request photos of the engine block, turbocharger side, radiator or cooling system, alternator, control panel, breaker area, base frame, and any refurbishment work already completed. If the unit is rebuilt or refurbished, ask which items were replaced, which items were cleaned or repaired, and which tests can be provided before shipment.
HXH has also published a practical generator inspection before shipment checklist for buyers who cannot visit the factory before delivery.
Match the model family to the project, not the other way around
Common high-power used generator demand includes Caterpillar, Cummins, MTU, and other industrial engine platforms. The right choice depends on local service familiarity, parts availability, project urgency, fuel conditions, and the buyer’s existing equipment base. A dealer who already supports one engine family may prefer a familiar platform even if another model is available at a lower purchase price.
When comparing options, ask the supplier to list available units by brand, model, frequency, approximate power range, condition, and readiness for inspection. If a buyer is comparing large Cummins and Caterpillar units, the CAT 3512 vs Cummins KTA50 comparison and the Cummins KTA50 vs QSK60 buying guide are useful starting points.
Check transport size, loading method, and destination port
A 1500kW used diesel generator is a heavy shipment. Before asking for CIF pricing, the buyer should provide the destination port and confirm whether the quotation should include only the generator set, accessories, spare parts, enclosure, radiator, control panel, or additional export documents. The shipping plan can differ sharply depending on the unit’s size, whether it is open type or containerized, and whether special loading equipment is needed.
For CIF comparison, the buyer should request a quotation basis that separates equipment condition, packing/loading, port, shipping scope, and document support. This reduces confusion when two suppliers appear to quote very different prices for similar power output. The CIF diesel generator quote checklist explains what should be confirmed before comparing offers.
What to send in a 1500kW RFQ
A good RFQ helps the supplier narrow the stock list quickly. For a 1500kW used diesel generator inquiry, send:
- Target power range and whether 1500kW is fixed or flexible.
- Standby, prime, or continuous duty requirement.
- Frequency, voltage, phase, and any grid connection requirement.
- Preferred brands or models, if any.
- Open type, canopy, containerized, or project-specific installation preference.
- Quantity and whether the project can accept equivalent alternatives.
- Destination country and port.
- Required proof files: photos, nameplates, test record, inspection video, packing/loading photos, or export documents.
- Purchase timeline and whether inspection before shipment is required.
A practical buying rule
For a high-power used generator, the cheapest listed unit is not always the lowest-risk option. A buyer should compare total landed cost, inspection confidence, parts support, shipping practicality, and how clearly the supplier can match the unit to the site. A supplier who can send current stock photos, condition details, and export proof before quotation is easier to judge than a supplier who only sends a broad catalog.
