Flood is usually an environmental hazard which has been increased in recent years by
forcing the pushing factors such as climate change and urbanization. This study
presents floodprone
area related to the electric substations for Tenaga Nasional Berhad
(TNB) in Peninsular Malaysia. The objective of this research was to identify the related
regions that the electric substations are in vulnerable condition by flood risk. For this
research, two types of maps are generated, namely flood inundation map (FIM), which
indicates the area and capacity of the flood, and flood hazard map (FHM), which
provides the area, depth, velocity, and extension of the flood for the TNB’s location of
substation. For this issue, different classes of substations are involved in analysis,
namely transmission main intake (PMU), main distribution (PPU), main switching
station (SSU), and distribution substation (PE). An integration of TNB’s substation
maps performed with FIM and FHM due to identify substations which are in floodprone
regions. Generally, result shows that Kelantan is classified as the highest floodprone
region for TNB’s infrastructures especially for PMU which they are affected by flood.
Kelantan, Terengganu, and Perlis are involved with the highest flooded, respectively,
based on PPU and SSU infrastructure. Finally, for PE substations, Kelantan, Perlis, and
Terengganu have the highest contribution for flooded substations for TNB’s structures.
