Dunhuang, China want to build solar power base
Dunhuang, one located in the Silk Road, the historic and cultural city, with bright well-known desert civilization and art. Here, the monuments to show the glory days are past, but in the outside corner of the vast Gobi Desert is brewing in recent years, the construction of a number of years ancient cultures co-exist with high-tech industries.
Enter the second decade of the 21st century, Dunhuang desert sun is creating a large-scale advanced modern industries - solar photovoltaic industry. According to the next round of the western development plan, it will be China's new energy base map is an important component.
With foreign correspondents last week to this group are being built into the desert to visit the local city photovoltaic PV industry. Dunhuang city 13 kilometers away in the clean energy industrial park, a large-scale photovoltaic power generation projects into the reporter's attention, reflects the development of China's ambitions in this regard.
SDIC Dunhuang 10 megawatts (MWp) Photovoltaic power generation demonstration project concession covers an area of about 500 acres (33 hectares), is the first large-scale photovoltaic power generation demonstration project concession. According to the Dunhuang PV SDIC any Tao, general manager, the project officially started in September last year, this month will be put into operation all the PV modules, the entire construction process less than a year.
China occupies the leading position of photovoltaic cells
China's current production capacity of photovoltaic cells occupy the dominant position, which in 2009 produced a total of 32% of the global battery. Mainland and Taiwan accounted for a total of 45% of the total global supply. In the photovoltaic industry in recent years, rapid development in China against the backdrop of this country to vote in the Dunhuang photovoltaic project is one hundred percent "Made in China."
Baoding Yingli Group, Jun Shi Fujian Energy Co., Ltd., Hefei Sunlight Power Supply Co., the manufacturer of photovoltaic panels and inverters, constitute the country's investment in the Dunhuang project. Ren Tao said: "All equipment, including control center equipment, all made in China, virtually no imported equipment."
The total project investment 179 million yuan (RMB, about 36 million dollars), designed annual generating capacity of 15,299,800 kwh (kWh). After the operation, the solar panels made of photovoltaic modules into the Northwest power grid will be integrated into national service in Xinjiang, Ningxia, Qinghai and other provinces. Photovoltaic power generation is still part of the high cost of power generation business, without government subsidies, corporate investment is not cost-effective.
Ren Tao pointed out that the cost of investment, the current unit of kilowatt hydropower needs 10,000 to 11,000 yuan or so per kilowatt of wind power is 11000-12000 yuan. The most expensive investment per kilowatt of photovoltaic power generation needs to 17,000 yuan.
He said the project is the electricity price per kilowatt-hour 1.0928 yuan, of which about 80% of the state subsidies. PV module life expectancy of 25 years, according to estimates, the entire power plant cost recovery period is 8 to 10 years, next year there will be 50 million to each of 700,000 yuan profit.
Dunhuang, long sunshine hours, annual sunshine time of 3310 hours of sunshine percentage of 75%, China's solar energy resource-rich region - with the development of photovoltaic power generation industry, special advantages, coupled with flat open, large-scale construction ideal strategy for large-scale photovoltaic power station development area.
In addition to national investment projects, currently built in Dunhuang China Guangdong Nuclear Energy Development Corporation of the Commonwealth 10 MW photovoltaic power generation projects.
In early May, the State Council issued "on the further support of a number of economic and social development in Gansu opinions", which calls for: "speed up to focus on solar power Dunhuang demonstration base, and strive to 2020 million-kilowatt solar power above the base."
Ren Tao said the completion of the first phase of 10 MW photovoltaic project, the second phase will start in the second half of this year, an additional 10 MW, one square kilometer of solar power plants could eventually be 30 megawatts of photovoltaic panels laid .
Ren Tao said: "In accordance with local planning Dunhuang, Dunhuang City, in 2020 the total installed capacity to reach 10 trillion, can be said here to the unparalleled, certainly one of the world's largest photovoltaic industry base."
