Recently, the first 20 MW phase of AVIC's 400 MW Distributed Photovoltaic Power Generation Demonstration Project was officially launched at the Shijiazhuang Tonghang Tongfei North China Company. This marks a significant milestone as it is the first large-scale distributed photovoltaic project initiated 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 develop and construct a large-scale distributed photovoltaic power plant on its own factory rooftops.
The project is designed to span across multiple provinces and cities. According to the project manager, AVIC's distributed photovoltaic project was approved by the National Energy Administration on April 23. With a total capacity of 400 MW and an investment of approximately 3.8 billion yuan, the project will be completed over three years. It is currently the largest distributed photovoltaic initiative in the country, with all components being installed on the rooftops of factories and other buildings spread across 20 cities in 11 provinces, including Beijing, Shanghai, Hebei, and Liaoning.
At the groundbreaking ceremony, Ma Xuewen, vice-minister of the Aviation Industry Department at AVIC, highlighted the unique advantages of building large-scale solar power stations on rooftops. He explained that the company’s factory and office buildings are all planned and designed uniformly, offering strong structural support and high load-bearing capacity, which makes them ideal for rooftop solar installations. Additionally, AVIC operates numerous factories with extensive roof areas, and clear ownership of these spaces further supports the development of large-scale photovoltaic projects.
The project will be implemented in four phases, based on sunlight availability, plant size, and electricity tariffs. The initial 20 MW phase will be constructed on the rooftops of large factories at the Shijiazhuang Aircraft Manufacturing Plant and the Shenyang Aircraft Manufacturing Plant, among others. Specifically, the Shijiazhuang Aircraft Factory will have a 4 MW installation.
According to Liang Tian, general manager of the project developer, Air China Huili, the 400 MW project is expected to generate around 440 million kWh in its first year, with a total output of about 11 billion kWh over 25 years. This will result in significant environmental benefits, including the reduction of approximately 4.4 million tons of standard coal, 10.93 million tons of carbon dioxide emissions, 330,000 tons of sulfur dioxide, and 165,000 tons of nitrogen oxides.
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 average power generation is around 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, making it a highly economically viable and sustainable initiative.
