Power Quality

Singapore has one of the most reliable supply of electricity.

Singapore’s electricity grid has an average interruption time of less than 1 minute per customer a year and is more reliable than Tokyo (4 minutes), New York (20.53 minutes), Hong Kong (23.40 minutes) and London (33.60 minutes)1.

Like all electricity supply systems, there is the occasional voltage dip, which is a momentary reduction in electricity supply voltage and not a power failure.

Voltage dips are generally caused by failure of high voltage equipment. Through proper maintenance of such equipment, we strive to keep the frequency of voltage dips in the electricity system to the minimum.

The table below gives information on voltage dip incidents in Singapore.

For the latest update on voltage dip incidents, consumers can call the SP PowerGrid Ltd’s 24-hour Electricity Service Centre at tel: 1800 778 8888 or regulatory action taken against Licensed Workers.
