What Affects Diesel Generator Price?
Understanding the cost drivers helps you compare quotes accurately and avoid overpaying for features you do not need.
- Engine brand: Cummins and MTU cost 20-40% more than domestic Chinese engines (Weichai, Yuchai) but offer better reliability and global service network.
- Alternator brand: Stamford, Leroy-Somer, and Marathon are premium; Chinese alternators (Engga, STC) reduce cost by 15-25%.
- Enclosure type: Silent canopy adds 25-40% over open type; containerized adds 50-80%.
- Voltage configuration: High-voltage (6.3kV/10.5kV) generators cost 30-50% more than low-voltage (400V).
- Control system: Basic AMF controller vs. advanced PLC + remote monitoring adds $2,000-$15,000.
- Certifications: CE, SASO, SONCAP add $500-$3,000 per unit for documentation and testing.
- Frequency: 60Hz generators may cost slightly more than 50Hz due to different alternator winding specs.

Hidden Costs to Watch For
When comparing generator prices, factor in these often-overlooked costs:
- Shipping: Sea freight from China to Lagos/Nigeria ~$2,500-4,500 per 20ft container; to Jebel Ali/UAE ~$1,200-2,000.
- Customs duties: Varies by country (Nigeria ~20%, Saudi 5%, Kenya 25%, Brazil 14-35%). Check HS code 8502.11/12.
- Spare parts: Budget 2-3% of generator price annually for filters, belts, and consumables.
- Installation: Electrical connection, fuel tank, exhaust, ATS integration — typically $2,000-10,000 depending on size.
- Commissioning: Factory engineer site visit (optional) — $1,500-5,000 + travel.
Frequently Asked Questions
How much does a 100 kW diesel generator cost?
A 100 kW diesel generator costs $7,000-$14,000 (open type) or $9,000-$18,000 (silent type) factory-direct from China, depending on engine brand (Cummins/Perkins) and alternator. FOB Qingdao pricing. Add shipping and customs for landed cost.
Why are Cummins generators more expensive?
Cummins engines cost 20-30% more than comparable Perkins or domestic engines due to premium build quality, global service network (190+ countries), and higher resale value. For mission-critical applications (data centers, hospitals), the premium is justified by lower downtime risk.
Can I get a price list PDF?
Generator prices fluctuate with raw material costs and exchange rates, so we provide custom quotes rather than a fixed price list. Send your specifications via WhatsApp (+86 151-5365-1777) and we will send a detailed quotation with model, specs, and price within 24 hours.
What is the cheapest diesel generator from China?
The most affordable configuration is an open-type generator with a domestic engine (Weichai/Yuchai) and Chinese alternator. A 20 kW open unit starts around $4,000 FOB. However, for export markets, we recommend at least a silent canopy and Cummins/Perkins engine for reliability and resale value.
Do you offer CIF or DDP shipping?
Yes, HPOWER offers FOB (Qingdao/Shanghai), CIF (to your port), and DDP (door-to-door including customs) shipping terms. DDP is popular for first-time importers who want hassle-free delivery. Tell us your destination port and we will quote all three options.
