SPG statistics showed that the first quarter has seen a total of 26 provincial power grids temporarily switch off electricity supply to alleviate power shortage.

In a breakdown, the maximum capacity for Beijing power grids hit 10.7 million kwh, up 13.4 percent over a year earlier, causing a shortfall of more than one million kwh. The maximum capacity for Tianjin power grids reached six million kwh, facing a shortfall of half a million kwh.

Deputy general economic administrator Xie Zhiguo of the Beijing Power Company said that the capital of China has mapped out a series of measures to avoid the power demand at rush hours.
