China's central government has formally approved plans that should see 3000 MW of additional wind capacity installed in the northern province of Gansu by 2010, with a longer term aim for a totalled installed provincial capacity of 10,000 MW by 2015 and 20,000 MW by 2020. Development will take place in and around Jiuquan in northwest Gansu, which is also home to one of China's main space centres. The aim is create the largest wind power base in China, transforming the region's Hexi Corridor, historically an important section of the old Silk Road, into the Wind Power Corridor. Last year, 210 MW of new wind capacity was installed in the province at the Yumen and Guazhou wind farms, bringing the region's installed capacity to 338 MW. From now on, local governments will not be able to rule out any wind projects under a recent provincial decree. Instead, all projects will be subject to tender and final decisions will be made by the provincial government for projects under 50 MW and by central government for larger projects.
