A 2 MW diesel generator package is usually a project purchase rather than a simple equipment order. The purchaser should confirm electrical output, duty rating, engine platform, cooling arrangement, switchgear boundary, site access, and acceptance documents before comparing commercial offers.
What buyers should know first
At this capacity, small missing details can change the package. A 50Hz site, 60Hz site, 400V system, 480V system, and medium-voltage project can each require different alternator, breaker, transformer, and protection planning. Review frequency selection basics before issuing the final RFQ.
Package review points
| Area | Question to answer | Purchasing risk if missed |
|---|---|---|
| Electrical output | What voltage, phase, frequency, and power factor are required? | Incorrect alternator or breaker selection |
| Duty profile | Is the set for standby, prime, or load-management use? | Wrong engine rating basis |
| Cooling and exhaust | Where will radiator air and exhaust discharge? | Overheating or installation rework |
| Fuel system | Base tank, day tank, or external fuel system? | Runtime or compliance problems |
| Testing | Which factory and site checks are required? | Approval delay before handover |

What an engineer should verify
- Load step requirement and acceptable voltage dip for major motors or UPS systems.
- Room ventilation, radiator airflow, exhaust back pressure, and maintenance clearance.
- Breaker rating, protection coordination, neutral treatment, and grounding arrangement.
- Fuel storage, refill procedure, local safety rules, and expected running hours.
- Lifting plan, skid dimensions, container loading, and route from unloading point to foundation.
Before requesting a quotation
Prepare a load schedule, single-line diagram, site layout, required voltage and frequency, preferred engine brand if any, enclosure requirement, test requirement, and packing requirement. Ask the supplier to state assumptions clearly instead of replacing missing project data with guesses.
Questions purchasers often ask
Is 2 MW the same as 2500 kVA?
It depends on power factor. Many enquiries use 0.8 power factor, where 2000 kW corresponds to 2500 kVA, but the project data sheet should confirm it.
Can one large generator replace several smaller units?
Sometimes, but redundancy, maintenance access, starting current, and site risk may favor multiple units.
What documents matter before payment approval?
Request the technical data sheet, outline drawing, wiring diagram, test report format, accessory list, and packing dimensions.
Should switchgear be included in the generator quotation?
Define the boundary clearly. Some projects need only generator-mounted breaker, while others require ATS, synchronizing, or separate panels.
Can the supplier advise on installation?
The supplier can give equipment requirements, but final room design and code compliance should be checked by the project engineer.
