500kVA Cummins Generator 50Hz/60Hz for Sale in Nigeria

A 500kVA Cummins Generator gives about 400 kW of real power at a 0.8 power factor, and buyers in Nigeria usually ask whether it is a 50Hz or a 60Hz diesel set before anything else.

Verified Supplier Network

We do not publish a single price for a 500kVA Cummins, because it swings with frequency, condition, canopy and the exchange rate. Send your specification and we will connect you with suppliers who can quote for Nigeria.

Buyers across Nigeria are mostly factories, hotels, hospitals, malls, estates and construction sites that cannot run on grid supply alone, plus oil and gas operators with onshore plants and offshore support bases.

Diesel or Gas?

Diesel sets are the default in Nigeria: fuel is easy to store and deliver, and a set can start anywhere
A gas set can cost less to run where pipeline gas, CNG or LNG is dependable, but it needs a gas supply and treatment, so confirm both before you switch
Many sites keep a diesel set as backup next to a gas set

50Hz or 60Hz in Nigeria

Nigeria's grid runs at 50Hz, so a set that backs up the grid or runs beside it has to be 50Hz
Almost all Nigerian requests are for 50Hz, because the national grid runs at 50Hz and the set has to match it.
A 60Hz set runs its engine at a higher speed (typically 1,800 rpm against 1,500 rpm at 50Hz) and is usually rated higher on the same engine, often by roughly 15 to 20 percent, so compare kVA ratings at the same frequency
A 60Hz set cannot feed a 50Hz network. Motors run fast and transformers can overheat unless a frequency converter is used

Buying a Cummins 500kVA Diesel Set in Nigeria

Buyers across Nigeria are mostly factories, hotels, hospitals, malls, estates and construction sites that cannot run on grid supply alone, plus oil and gas operators with onshore plants and offshore support bases.
Imported sets usually clear at Apapa, Tin Can Island or Onne and then move to site by low-bed trailer, so delivery time depends on how far site is from the port.
Confirm weight, footprint and lifting points on the data sheet, and plan a concrete plinth and crane or skid positioning at site

What to Check Before You Pay

Frequency (50Hz or 60Hz), voltage and phase on the rating plate, not only in the advert
Engine hours, service history and whether the set was prime or standby duty
A load-bank test at 75% load or more, with the readings recorded
Alternator insulation test, coolant and oil condition, and turbocharger condition
Fuel system condition, filters and injector service records
Control panel type, whether an ATS is included, and what the warranty covers

Onshore and Offshore Use

Onshore: factories, estates, hospitals, malls, flow stations and processing plants, usually on 50Hz grid backup or prime power
Offshore and marine support: platform and vessel installations normally need a set built and certified to the platform's or vessel's class rules, and often 60Hz, so a standard onshore set is generally not enough
Tell us whether the set goes onshore or offshore when you ask, because it changes the frequency, enclosure and certification you need

500kVA Cummins Generator at a Glance (50Hz)

Real power at 0.8 power factor: about 400 kW
Full-load current at 415 V three-phase: about 696 A
Diesel use at 75% load: about 78 litres per hour (planning figure)
Cummins sets at 500kVA are built on QSX-series or KTA-series diesel engines. Confirm the exact model and build year on the supplier's data sheet

Frequently Asked Questions

How much does a 500kVA Cummins diesel generator cost in Nigeria?

We do not publish a fixed price, because it moves with frequency, new or used condition, engine hours, canopy, control panel, delivery to Nigeria and the exchange rate. Send your requirement on WhatsApp and we will get comparable quotes.

Is a Cummins 500kVA generator 50Hz or 60Hz?

Cummins builds this size for both frequencies, and the rating differs between them. Nigeria's grid is 50Hz, so choose 50Hz for grid backup and choose 60Hz only when the equipment it powers is built for 60Hz.

How much diesel does a 500kVA generator use?

Roughly 78 litres per hour at 75% load, or about 1872 litres over 24 hours. Actual use varies by engine, load and condition, so ask for the manufacturer's fuel curve for the exact model.

Can a 60Hz generator power Nigerian grid loads?

Not directly. A 60Hz set produces 60Hz output, so 50Hz motors run about 20 percent fast and transformers and sensitive electronics can be damaged. Use a frequency converter or choose a 50Hz set.

Can this generator be used offshore?

Offshore and marine installations normally need a set built and certified to the platform's or vessel's class rules, so a standard onshore set is generally not enough. Tell us the requirement and we will ask suppliers what they can certify.
