Singapore’s electricity supply is amongst the most reliable in the world. Our utilities companies and consumers are key partners in maintaining the high quality of the electricity supply.

Like all electricity supply systems, there are occasional incidents of voltage dips. A voltage dip 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 high voltage equipment, we strive to keep the frequency of voltage dips in the electricity system to the minimum.

The table below gives information on such 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.
