First large-scale distributed photovoltaic power generation project started
Recently, the first 20 MW project of the AVIC 400 MW Distributed Photovoltaic Power Generation Demonstration Project was started in Shijiazhuang Tonghang Tongfei North China Company. This was the first large-scale distributed photovoltaic power generation project started in China after the State Council issued the “Some Opinions on Promoting the Healthy Development of the Photovoltaic Industry†(hereinafter referred to as the “Opinionsâ€) on July 15. The China Aviation Group has also become China's first use. Build a large-scale central enterprise of distributed photovoltaic power plants on the roof of its own plant. Project overall package Across multiple provinces and cities According to the person in charge of the project, AVIC's distributed photovoltaic power generation demonstration project was approved by the National Energy Administration on April 23. The total project size is 400 megawatts, with a total investment of about 3.8 billion yuan and a construction period of three years. It is the largest distributed photovoltaic power generation project in the country and will be wholly packaged and constructed on the roofs of factory buildings and other buildings distributed in 20 cities in 11 provinces including Beijing, Shanghai, Hebei and Liaoning. At the groundbreaking ceremony, Ma Xuewen, vice-minister of the Aviation Industry Department of AVIC, said: The biggest advantage of the large-scale distributed power station built by AVIC Group is on the roof. Firstly, the factory buildings and office buildings of all member companies are all unified in planning and design, with a solid building structure and a large load insurance index, which facilitates the unified design and construction of rooftop power stations. Second, the AVIC Group has a large number of factories, a large roof area, and roof-top property. The relationship is clear and it is also conducive to the construction of large-scale photovoltaic power plants. The project will be promoted in four batches according to sunshine conditions, plant size, and basic electricity prices. The first 20MW projects to be started will be implemented on the roofs of large-scale factories in Shijiazhuang Aircraft Manufacturing Plant, Shenyang Aircraft Manufacturing Plant and other units. Among them, the construction scale of the Shijiazhuang Aircraft Factory is 4 MW. According to Liang Tian, ​​general manager of the project developer, Air China Huili, the 400 MW distributed photovoltaic power generation project (according to the three types of sunshine, with a daily average of approximately 3.5 hours of sunshine), builds a power generation capacity of about 440 million kWh in the following year, totaling 25 years. The generating capacity is about 11 billion kWh, equivalent to saving about 4.4 million tons of standard coal, about 10.93 million tons of carbon dioxide emission reduction, 330,000 tons of sulfur dioxide emissions, and 165,000 tons of nitrogen oxides. The economic and social benefits are very considerable. The first batch of 20MW projects uses photovoltaic modules with a conversion efficiency of more than 15%. The system design efficiency is 80%, and the average daily power generation capacity is 60,000 degrees. The average annual power generation capacity is 22 million degrees, and the expected return period is about 10 years.
