State media has described the crisis as China’s worst-ever power shortage. With coal prices soaring and supplies disrupted by some of the most severe winter weather in years, it is certainly the most acute since 2004 when demand outstripped supply by 40 gigawatts. A rush for individual generators and to buy diesel to fuel them sent state firms into the international markets, provoking a spurt in crude oil prices.
So worried is the government that on Friday it put in place a two-month ban on coal exports. The Ministry of Communications said: “During the Chinese New Year and parliamentary meeting, all thermal coal exports will be suspended. Where there is a need, all international shipping capacity will be diverted for domestic transportation requirements."
The coal shortages have forced the five biggest electricity producers to close 90 power stations - with a combined capacity of more than 20,000 megawatts - in northern and central China. Coal stockpiles at the plants have dropped below the "caution mark" of three days' requirements. Officials have ordered some mines, which had closed as part of a sweeping crackdown on unsafe collieries in which some 3,000 people die each year, to reopen if they are deemed now to have met safety standards.
The shortage could not have come at a worse time for the ruling Communist Party. The leadership is anxious to ensure plentiful supplies of power for the most important holiday of the year, the Lunar New Year holiday,which begins on February 7, just as rising prices – particularly for food – are fuelling popular discontent.
