Authorities plan to shut down small power generators with a total annual capacity of 50 million kW by 2010 to reach the nation's energy consumption target, Vice-Premier Zeng Peiyan said yesterday. Addressing a national conference on controlling energy consumption, Mr Zeng said the power industry should speed up adjustments to its industrial structure by eliminating inefficient, environmentally unfriendly small power generators and develop generators using recyclable energy, Xinhua reported. Mr Zeng said the move would contribute to reaching the energy consumption target set for the 11th Five-Year Programme (2006-2010), which called for a 20 per cent drop in energy consumption per unit of gross domestic product and a 10 per cent cut in pollutant discharges. Beijing missed its targets last year. The mainland's small generators, those with a capacity of less than 100,000 kilowatts, are capable of producing 115 million kW but consume 400 million tonnes of coal and release 5.4 million tonnes of sulfur dioxide each year, according to the report. Power plant officials from 30 provinces signed a pact with the National Development and Reform Commission yesterday to shut almost half the small generators by 2010.
