Factories in the Pearl River Delta, a main Chinese industrial hub, have been asked to cut power for up to four days per week as drought and a coal shortage reduce electricity supply from the West-to-East Electricity Transmission Project.

Guizhou, the leading province in the project on which many manufacturers in the delta depend, has only generated two thirds of its planned output over the first half of 2011. Daily electricity transmission has slumped from 154 kWh to 100 kWh.

Lack of rain has cut generation from the Goupitan hydropower station – Guizhou’s largest – to a tenth of its normal level. Thermal power generation has also dropped by 10 per cent in the province due to reorganization of mines and closures of shafts over safety concerns.
