Work begins on solar power tower plant
Print Edition
CONSTRUCTION has begun on China’s largest solar power tower plant in the northwestern province of Qinghai.
Occupying 2,550 hectares of the Gobi Desert near the city of Golmud, the facility will have an installed capacity of 200 megawatts, and be capable of supplying electricity to 1 million households, according to Qinghai Solar-Thermal Power Group.
“Its designed heat storage is 15 hours, so it can guarantee stable, continual power generation,” said Chairman Wu Longyi.
Once operational, the plant will cut annual coal use by 4.3 million tons, and reduce emissions of carbon dioxide and sulfur dioxide by 896,000 tons and 8,080 tons, respectively.
Using heliostats to focus sunlight onto a central tower for power generation, the system boasts a higher efficiency and better energy storage than the more commonly used trough system.
Located 2,870 meters above sea level, Golmud has favorable conditions for the development of the new-energy industry, said Wu Tianxiao, the city’s deputy Party secretary.
The plant will be China’s first large-scale solar power plant under commercial operation, said Yu Mingzhen, vice director of Qinghai development and reform commission.
China has been focusing on increasing its proportion of clean energy. As of the end of last year, its solar power capacity was 28 gigawatts, 400 times more than 2005, and this is set to grow to about 100 gigawatts by 2020.
On Tuesday, the Tibet government said the region has increased its solar power capacity to 200MW and 600,000 people use solar electricity.
