Welcome to EMA’s new website. We would love to get your valuable feedback through FormSG.
To maintain the power quality to consumers, EMA tracks voltage dip incidents which affect supply voltage.
Singapore's power system is one of the most reliable in the world. According to a benchmarking study by SPPG-DNV GL, Singapore has an average interruption time of less than 1 minute per customer a year.
Like all electricity supply systems, occasional voltage dips can happen. These are momentary reductions in electricity supply voltage but do not lead to power failure.
As voltage dips usually occur due to the failure of high voltage equipment, the frequency of incidents can be minimised through proper maintenance of such equipment.
For the latest update on voltage dip incidents, consumers can call SP Powergrid Limited's 24-hour Electricity Service Center at 1800 778 8888 for regulatory action taken against licensed workers. To view the regulatory action against licensed workers, please click here.
