Solar power boosts Qinghai into "low carbon era"

Xinhua Net Xining, August 8th. As of the end of July this year, of the 33 solar power stations planned in Qinghai Province in the Qaidam Basin, 5 have been connected to generate 56 megawatts of electricity, which has become China’s under construction and completed. One of the largest solar photovoltaic power generation bases. The western province, which is located in the ecologically sensitive area of ​​the Qinghai-Tibet Plateau, is trying to achieve sustainable development of the economy through "the power to the sky."

The solar radiation in the Qaidam Basin in Qinghai Province is intense, with an average annual sunshine of more than 3,100 hours and a radiation of 6,950 megajoules per square meter. And it has a 330kV dual-loop power grid such as Chengyu Ug. According to Hu Yuqing, a staff member from the Science and Technology Department of Qinghai Province, the results of the study showed that the comprehensive conditions for the development of high-voltage grid-connected high-voltage photovoltaic power plants above the GW level in Qinghai Province ranks first in the country.

“Take electricity to heaven”, all photovoltaic power plant projects in Qinghai Province are well underway in the Qaidam Basin. Yang Lanxue, a senior engineer of the Energy Development Bureau of the Qinghai Provincial Development and Reform Commission, said that among the many planned power stations, the Qinghai Provincial Development and Reform Commission has approved 12 solar photovoltaic power stations with a capacity of 195 megawatts. Among them, CGNPC Solar Power Co., Ltd. Xi Tieshan 10 MW photovoltaic power station is all connected to the grid for power generation. The accumulated investment was 1.1 billion yuan. In the first quarter of 2011, an investment of 700 million yuan was completed.

Solar photovoltaic applications in Qinghai started earlier. Before the 1990s, the photovoltaic power generation market in Qinghai was mainly supported by the National Poverty Alleviation Project. During the "10th Five-Year Plan" period, the application of solar photovoltaic power generation system in Qinghai was accelerated Through international cooperation between China and Japan, China and Germany, and series demonstration projects, Qinghai Province has effectively explored the experience of building solar grid-connected photovoltaic power plants.

To support the development and construction of new energy, Qinghai Province took the lead in launching the research on new energy grid-connected technologies. According to the requirements of the “General Plan for Comprehensive Solar Energy Utilization in Qinghai Province,” it is determined that a 1,000 MW photovoltaic power station can be accepted in 2015. Yu Xiaoming, director of the Energy Development Bureau of the Qinghai Provincial Development and Reform Commission, said that around the solar power generation industry, solar photovoltaic material systems based on solar silicon materials are also being formed in Qinghai Province. More than 20 companies such as Asia Silicon (Qinghai) Co., Ltd. and the Upper Yellow River Hydropower Development Company are under development. Solar silicon material production enterprises have formed a production capacity of nearly 5,000 tons.

Relevant statistics show that in 2009, the photovoltaic output value of Qinghai Province has reached 400 million yuan, reached 1 billion yuan in 2010, and will reach 10 billion yuan during the 12th Five-Year Plan period. By 2013, through cooperation with photovoltaic companies at home and abroad, the photovoltaic industry in Qinghai Province will build a complete photovoltaic chain. At that time, it will promote the rapid development of related industries in the downstream to form a solar energy industry cluster with an output value of more than 70 billion yuan, making solar power generation account for 5% of the province's total power generation.

Yu Xiaoming said that by 2015, the installed capacity of solar photovoltaic systems such as household appliances, photovoltaic building integration (BIPV) and photovoltaic lighting in Qinghai Province will reach 50 megawatts, and the installed capacity of large-scale desert photovoltaic grid-connected power stations will reach nearly 1,100 megawatts; by 2020 A complete photovoltaic industry chain will be built, and the annual output value of the solar photovoltaic industry will reach 100 billion yuan, which will become an important force for the development of emerging industries in Qinghai Province and an important pillar industry in the industrial field.
