BEIJING, July 19 (Xinhuanet) -- The world's largest stand alone integrated photovoltaic (BIPV) project started transmitting power to the grid in Shanghai on Sunday in another move showcasing China's commitment to reduced carbon emissions.
The 6.68-megawatt solar system can produce 6.3 million kilowatt-hours (kwh) of electricity per year to meet the needs of 12,000 Shanghai households. It will cut coal consumption by 2,254 tons, while reducing carbon emissions by 6,600 tons.
The project has been installed on the awnings on both sides of the newly completed Hongqiao Station of the Beijing-Shanghai High-Speed Railway. Its 20,000 solar panels cover a roof area of 61,000 sq m and have produced 300,000 kwh power since the 160 million-yuan project began operation two weeks ago.
"The project is another manifestation of China's commitment to reducing carbon emissions to fight climate change. It comes after the country set a voluntary target of cutting carbon intensity per unit of GDP by 40 to 45 percent by 2020," said Yu Hailong, general manager of the Beijing-based China Energy Conservation and Environmental Protection Group (CECEP), the project's developer.
"As a pilot project, it will help stimulate the development of solar energy in China and promote the construction of more environmentally friendly railway stations," he said.
Chief engineer of the Ministry of Railway Zheng Jian said China will further encourage BIPV implementation at railway stations, which serve as an ideal vehicle to promote the technology.
A 2.2-MV BIPV system has also been installed at the Wuhan Station of the Wuhan-Guangzhou High-speed Railway. The system was connected to the national grid in May, CECEP deputy manager Chen Shuguang said.
"BIPV technology does not take up extra space, because it is integrated into buildings' design and construction. It is especially suitable for China's eastern areas, where there are limited land resources yet greater energy demand," Chen said.
