Shanghai leads in power supply stability

Shanghai has one of the most stable power supply systems in the world, according to statistics revealed by the State Grid Shanghai Company.

Data shows that the power stability rate of the city so far this year has reached 99.9956 percent, with a higher rate of 99.9998 percent for central urban areas.

This means the average power-cut period per user is less than 5 minutes per year. This makes Shanghai not only the most reliably powered city in China, but also puts it on par with Tokyo and Singapore, while surpassing cities like New York, London and Paris.

By April, the average power-cut period for each household in central urban areas was less than half a minute.

Moreover, the power failure rate in Shanghai's central urban area this year fell 22.7 percent compared with last year, thanks to the efforts by the State Grid in optimizing the capacity and auto-inspection function of its equipment.

The company is also looking to advance in the electricity access goals set by the World Bank, which ranks China 12th in the world in terms of the availability of power supply for enterprises.

The application of live working technology, which means that electric devices can be serviced without turning off power, is also a new focus for State Grid so users don’t have to go through blackouts during facility safety inspections.

The number of power cuts for repairs this year has reduced 37 percent compared with last year, with an average period of 4.85 hours each time.
