Technical Characteristics of High-Capacity Generators
A 2500 kVA diesel generator set typically delivers approximately 2000 kW of active power at 0.8 power factor — equivalent to the total electrical demand of a significant commercial building or major industrial process. The diesel engine at this power level is a large, multi-cylinder machine — typically a V12 or V16 configuration with 30 to 100 liters of displacement — that must manage precise fuel injection, thermal management, and combustion control to achieve both rated power output and the efficiency and emission standards applicable to new installations in the UAE. The alternator must produce stable voltage and frequency across the full range of load variations that large facilities experience. And the control system must manage this complex machine reliably and safely, with comprehensive protection against the wide range of fault conditions that can occur in industrial electrical environments.
Civil Engineering for Large Generator Installations
Installing a generator of this scale requires careful civil engineering preparation that must be completed before the generating set arrives on site. The generator foundation must be designed specifically for the equipment weight — which may be 20 tonnes or more for a large enclosed generator set — and the dynamic forces generated during operation. Foundation design by a qualified structural engineer is essential rather than using generic foundation specifications that may not be appropriate for the specific equipment and site conditions. Generator room or external enclosure must be designed with sufficient dimensions for the equipment with maintenance access clearances, adequate ventilation for cooling and combustion air, and the fuel, exhaust, and cable penetrations needed for the complete installation.

High-Voltage Generator Sets for UAE Industrial Facilities
Very large generator sets — including 2500 kVA and above — are typically designed to generate at medium voltage (6.6 kV or 11 kV) rather than low voltage, because the current at 415V for 2500 kVA (approximately 3500 amperes) would require impractically large cable sizes to carry from the generator to the switchboard. Medium voltage generator sets require medium voltage switchgear, step-down transformers for distribution to load circuits at low voltage, and special commissioning and maintenance expertise. FG Wilson UAE has the technical capability to supply and commission medium voltage generator sets for large UAE industrial and commercial installations where this configuration is required.
Fuel Consumption and Autonomy Planning
At 2000 kW output, a large diesel generator set consumes approximately 500 to 600 liters of fuel per hour at full load — meaning that providing 24 hours of backup autonomy requires approximately 12,000 to 14,000 liters of diesel storage capacity. This substantial fuel storage requirement has significant implications for site planning — space for tanks, bunded containment to hold the full tank volume in the event of a spill, fuel delivery logistics, and fire safety design for large fuel storage are all important considerations. For installations where very long backup autonomy is required, multiple day tanks with automatic refilling from a main storage tank can manage the fuel logistics while minimizing the fuel volume held in the generator room itself.
Parallel Operation for Resilience and Redundancy
For critical applications where no interruption to power supply can be tolerated even for the few seconds that a generator requires to start, parallel generator configurations where two or more generators operate simultaneously provide the active redundancy needed. If one generator fails while operating in parallel with others, the remaining units immediately pick up the failed unit’s load share without any interruption to supply. Parallel operation also allows generators to be taken offline for maintenance while the remaining units continue to supply the load. FG Wilson UAE designs parallel generator installations for critical UAE facilities where active redundancy is a requirement.
Load bank testing is the definitive verification that a generator installation will perform correctly under actual load conditions. When a generator is commissioned at a facility where the initial connected load is insufficient to test the generator at full rated output, a portable load bank — a resistive or reactive load testing unit — provides the missing load to allow full-load testing. FG Wilson UAE provides load bank testing services using calibrated load banks that can be delivered to site and connected to any generator installation for comprehensive performance verification.
