CASE STUDY

330 kVA Cummins Generator Containerised
Solutions for Government Water Pump Station

 
 

Project Overview

A government body responsible for water infrastructure and rural service delivery required a mobile, self-contained power solution to support water pump stations during grid outages. The application demanded a rugged yet highly engineered generator system capable of being rapidly deployed in remote areas while ensuring quiet operation and minimal environmental impact.
 
The need was for a mobile, plug-and-play power source to guarantee continuity of critical water supply services in emergency situations or during scheduled maintenance.
 

Client Requirement

The client sought a purpose-built generator system with the following key specifications:
 
  • Prime-rated generator capacity between 300 kVA
  • Custom-built switchboard and gang box for safe, multi-point power distribution
  • Noise levels within residential limits to meet urban deployment regulations
  • Containerised design for secure transport and durability
  • Capability to integrate renewable power sources 
  • Turnkey delivery with full engineering, commissioning, and support services
 

Solutions

Macfarlane Generators engineered and delivered a fully containerised Cummins diesel generator system, featuring the Cummins C330D5 unit rated at 330 kVA (264 kW). The design focused on delivering reliable, clean power while meeting complex logistical, operational, and compliance requirements.
 
Key solution highlights included:
 
  • Engine: Cummins 6LTAA9.5-G3 – delivering strong performance and durability under variable load profiles
  • Alternator: Stamford UC series – ensuring stable voltage regulation for sensitive pumping equipment
  • Containerisation: Custom 20-ft ISO container – modified to include ventilation, lighting, and dual-access service doors
  • Sound Attenuation: Residential-grade silencing and acoustic insulation – reducing operational noise
  • Switchboard & Gang Box: Engineered in-house for high flexibility and safety, allowing rapid connection to pump stations
  • Solar Integration: Rooftop solar array mount – enabling auxiliary DC power generation or future hybridisation
  • Mobility: Forklift pockets for fast relocation and field deployment

 

Results

The unit was successfully delivered to the end user, meeting all expectations in terms of performance and reliability. The quality of the equipment, combined with the speed of delivery and the professionalism of the Macfarlane Generators team, ensured a smooth handover process. The solution delivered both immediate operational value and long-term dependability—crucial for supporting the customer’s continuous operations.
