Generator Sizing Guide for Nigerian Businesses

Direct answer

What is the short answer?

Calculate generator capacity by listing all running loads, converting kW and kVA correctly and checking the highest motor starting current. Add only a justified project margin, then verify voltage, frequency, duty rating, ambient conditions, ATS and future expansion with the supplier.

Step-by-step guide

How to Calculate Generator Capacity

  1. Create the load listRecord each load's running power, quantity and operating priority.
  2. Convert ratingsConvert between kW and kVA using the correct power factor.
  3. Calculate running demandAdd only loads expected to operate at the same time.
  4. Check starting demandModel the largest motor start and simultaneous starting sequence.
  5. Choose duty and marginSelect standby or prime rating with a justified allowance.
  6. Verify the siteConfirm voltage, frequency, temperature, ventilation, ATS and expansion.

What to Check

Confirm load, kVA/kW rating, fuel availability, operating hours, enclosure type, ATS requirement, installation conditions and local service support.

How CNV POWER × POLKINS Helps

CNV POWER provides generator manufacturing and configuration, while POLKINS supports Nigeria local production, installation, spare parts and maintenance.

Buyer Checklist Before Quotation

  • Confirm whether the diesel generator set will run as standby, prime or continuous power.
  • List running loads, starting loads, motor loads, pumps, HVAC, elevators, compressors and future expansion.
  • Confirm voltage, frequency, phase, power factor and whether 400V or 415V output is expected.
  • Decide open, silent, mobile or containerized layout based on noise, weather, space and maintenance access.
  • Check ATS, AMF, synchronizing, N+1 redundancy, output cabinet and remote monitoring requirements.
  • Prepare site information for ventilation, exhaust routing, foundation, fuel storage, cable route and safety clearance.
  • Confirm spare parts, filters, service intervals, commissioning support and operator training.

FAQ

What should buyers check for How to calculate generator capacity??

Buyers should check generator size, duty rating, fuel type, enclosure, ATS, spare parts, installation support, maintenance plan and warranty terms.

Can POLKINS support this in Nigeria?

Yes. POLKINS supports Nigeria projects with local production, assembly, installation, commissioning, spare parts and maintenance.

How do I request a quotation?

Send load requirement, voltage, frequency, application, fuel type, quantity, site location and preferred configuration by form, email or WhatsApp.

How should buyers choose the right generator size?

Buyers should calculate running load, starting current, voltage, frequency, power factor, duty rating, expansion margin, site environment and whether ATS or parallel operation is required.

Why does local service matter for generator projects in Nigeria?

Local service helps with site communication, installation guidance, commissioning support, spare parts access, maintenance planning and faster response when equipment needs attention.

Request a Configuration

Send your load schedule, site location, fuel preference, operating hours and required delivery scope. The team can review whether an open, silent, containerized, gas, diesel, ATS or parallel configuration is more suitable for the project.
