Inter-Emirate High-Voltage Grid Backbone
The 85 km 400 kV double-circuit line traverses the Hajar mountain range to connect the Fujairah desalination complex to the national transmission grid.
The transmission towers are built to withstand coastal corrosion and harsh mountain conditions, ensuring 1200 MW of continuous power flow.
Transformation Capacity and Northern Emirates Reliability
At the Fujairah substation, 2 autotransformers rated at 500 MVA each provide 1000 MVA of step-down transformation to the 132 kV regional grid.
Fast numerical distance protection relays clear line faults in under 30 ms, enhancing the operational stability of water desalination and power supply.
