### Project Background

Aruobemi Rice Processing Co., Ltd. operates a 24-hour rice milling facility in Delta State, Nigeria. With an annual processing capacity of 5,000 tons, the factory relies heavily on continuous power supply for cleaning, dehulling, polishing, and packaging operations. Frequent grid outages averaging 8 hours per day were causing significant production losses and equipment damage.

### The Challenge

- Unstable national grid with 8+ hours of daily power outages

- High diesel costs making backup power economically unsustainable

- Need for automatic power transfer to protect sensitive processing equipment

- Limited technical support infrastructure in the region

- Local natural gas pipeline available — diesel generators not optimal

### Our Solution

After analyzing the factory's power consumption profile (peak load: 120kW, average: 95kW), our engineering team recommended the **SE150NF Natural Gas Generator Set** with the following specifications:

- **Prime Power:** 150kW / 187.5kVA @ 1500rpm, 50Hz

- **Engine:** Cummins 6CTA8.3-G2 (direct injection, turbocharged)

- **Alternator:** WATTEK WHI274L with AVR regulation

- **Control System:** DEIF AGC 420 automatic paralleling controller

- **Fuel Type:** Natural gas (with LPG conversion capability)

- **Emission Standard:** EPA Tier 2 / CE certified

We also provided:

- Customized gas预处理系统 (gas preprocessing unit) to stabilize gas supply pressure

- Automatic Transfer Switch (ATS) for seamless grid-to-generator switching

- Remote monitoring module with SMS alert functionality

- On-site commissioning and 72-hour load testing

### Results

| Metric | Before | After |

|--------|--------|-------|

| Daily Power Outages | 8 hours | < 30 minutes |

| Monthly Produc

tion Uptime | 65% | 99.2% |

| Annual Fuel Cost (Energy) | $185,000 | $128,000 |

| Equipment Damage Incidents | 12/year | 1/year |

**ROI Achieved:** 14 months  

**Customer Feedback:** "The Chinese team responded to our inquiry within 2 hours. They understood our gas supply situation and recommended the right generator size. The 150kW unit has been running flawlessly for 18 months." — Mr. Emeka Okonkwo, Factory Owner

### Why This Matters

Nigeria's rice milling industry faces chronic power challenges. Natural gas generator sets offer a cost-effective, reliable alternative to diesel — reducing fuel costs by 30-40% while providing cleaner, more stable power. The Aruobemi project demonstrates that Chinese-made gas generators can compete at the highest international standards.
