The first 20 MW phase of the AVIC 400 MW Distributed Photovoltaic Power Generation Demonstration Project has officially commenced at the Tonghang Tongfei North China Company in Shijiazhuang. This marks a significant milestone as it is the first large-scale distributed photovoltaic project to be launched in China following the release of the State Council's "Some Opinions on Promoting the Healthy Development of the Photovoltaic Industry" on July 15. AVIC has now become the first major central enterprise in China to build a large-scale distributed photovoltaic power system on its own factory rooftops.
The project, which was approved by the National Energy Administration on April 23, spans across 20 cities in 11 provinces, including Beijing, Shanghai, Hebei, and Liaoning. With a total investment of approximately 3.8 billion yuan and a construction period of three years, it is currently the largest distributed photovoltaic project in the country. The entire project will be developed on the rooftops of factories and other buildings, with a total capacity of 400 megawatts.
At the groundbreaking ceremony, Ma Xuewen, Vice-Minister of the Aviation Industry Department at AVIC, emphasized that one of the key advantages of this project is the availability of suitable rooftops. He noted that the company's factory and office buildings are all designed with unified planning, featuring strong structural support and high load-bearing capacity, making them ideal for installing solar power systems. Additionally, AVIC owns numerous factories with large roof areas, and clear property rights make it easier to implement large-scale solar projects.
The project will be rolled out in four phases, depending on local sunlight conditions, plant size, and electricity pricing. The initial 20 MW phase will be constructed on the rooftops of large factories, including those at the Shijiazhuang Aircraft Manufacturing Plant and the Shenyang Aircraft Manufacturing Plant. The Shijiazhuang site alone will have a capacity of 4 MW.
According to Liang Tian, General Manager of the project developer, Air China Huili, the 400 MW project is expected to generate about 440 million kWh in the first year, with a total output of around 11 billion kWh over 25 years. This will result in significant environmental benefits, including saving approximately 4.4 million tons of standard coal, reducing carbon dioxide emissions by about 10.93 million tons, sulfur dioxide by 330,000 tons, and nitrogen oxides by 165,000 tons. The economic and environmental returns are substantial.
The first batch of the 20 MW project uses photovoltaic modules with a conversion efficiency exceeding 15%, and the system design efficiency reaches 80%. The daily power generation capacity is about 60,000 kWh, with an annual output of 22 million kWh. The project is expected to achieve a return on investment within about 10 years.
