What is the maximum timeline for the Penang Bridge electrical cable repairs?

Question

Accepted Answer

The maximum timeline for Penang Bridge electrical cable repairs is three months.

The repair work on the electrical cables of the first Penang Bridge, which caught fire, is estimated to take a maximum of three months to complete. Tenaga Nasional Berhad (TNB) will be undertaking these repairs, with discussions ongoing with PLUS Expressways regarding the necessary lane closures. The fire occurred at KM3.2 of the bridge, damaging three circuits.
Repair timeline and scope

The state infrastructure and transport committee chairman, Zairil Khir Johari, stated that the electrical cable repair works are expected to take no more than three months. This timeline was provided by TNB, although it is subject to finalisation after detailed investigations into the extent of the damage. The severity of the damage and ongoing discussions with PLUS Expressways about lane closures will influence the precise schedule.
Lane closure considerations

Discussions are underway between TNB and PLUS Expressways to determine the extent of lane closures required for the repair operations. While possibilities such as closing one lane on each side of the bridge, specifically at night, are being considered, the final decision will depend on the scope of repairs needed. TNB is expected to announce the outcome of these discussions soon.
Cause and impact of the fire

The fire, which occurred at approximately 4:23 PM yesterday, damaged three electrical circuits located beneath the bridge. This incident resulted in a brief power supply disruption of about 35 seconds in several areas. However, power supply was quickly restored and remains stable due to the availability of alternative power sources. TNB is currently investigating the exact cause of the fire.
Power supply stability

Despite the disruption caused by the fire, the power supply to Penang Island remains stable. The island's power demand is approximately 700MW. Currently, there are four other submarine cable circuits with a combined supply capacity of 1,180MW, and the Gelugor Power Station can provide an additional 310MW. This collective capacity of about 1,490MW significantly exceeds the demand, ensuring a sufficient and stable power supply.
