When the project started, the excavator broke the ice and excavated, and the whistle roared. Four major clean energy projects in Chengdu and Chongqing kicked off the construction. On December 14, 2021, Dingmubazi, Zhengdou Township, Xiangcheng County, Ganzi Prefecture, at an altitude of 4000 meters, the sun was just right, and the SPIC Sichuan Ganzi Prefecture Township Zhengdou Photovoltaic Demonstration Base Project was officially launched. The project has a total installed capacity of 400,000 kilowatts and a total investment of 2.24 billion yuan. It is currently the largest single-scale photovoltaic power generation project in Sichuan Province. It is planned to be completed and put into operation in September 2022.

This is also the world’s first ultra-high-altitude photovoltaic demonstration base. After completion, it will explore solutions for photovoltaic power generation in ultra-high-altitude areas. The demonstration results can be used for equipment product selection, project planning and design, project construction organization and Provide valuable experience and data support in management, intelligent application, and establishment of energy development models.

Zhengdou Photovoltaic Demonstration Experimental Base Project is located in Dinggong Prairie, Zhengdou Township, Xiangcheng County, Ganzi Prefecture, Sichuan Province. After the completion of the project, it can generate approximately 774 million kilowatt-hours of electricity annually, save 238,000 tons of standard coal and reduce carbon dioxide emissions. 650,000 tons.

As the world's first ultra-high altitude photovoltaic demonstration base, what are the characteristics of the project different from ordinary photovoltaic demonstration bases? At the launching ceremony, Zhou Qingjia, Secretary of the Party Committee and Chairman of the Sichuan Company of State Power Investment Corporation, and Chairman and General Manager (Dean) of the Southwest Energy Research Institute, introduced this.

"Different from a simple photovoltaic power station, the photovoltaic demonstration base is like the "encyclopedia" of the photovoltaic industry." Zhou Qingjia said that the more far-reaching value of the demonstration base is to explore the development of photovoltaic technology and improve the efficiency and cost-effectiveness of photovoltaic power generation. Zhengdou Photovoltaic Demonstration Base initially designed 127 empirical comparison schemes. Through a set of customized data analysis and acquisition system, the optimal technical solution was verified.

Project Features

The first is that the project is located in an ultra-high altitude area of 4,000 meters. At present, mountain photovoltaics have become the focus of innovation and attention in the industry. However, ultra-high altitude and mountain climate have an impact on equipment operating efficiency, equipment insulation performance, and energy storage equipment thermal insulation performance. The implementation of this project will fill my country’s photovoltaic demonstration base in super The gaps in high-altitude and mid-latitude regions provide a reference for photovoltaic construction in the Sichuan-Tibet Plateau and similar scenarios across the country.

The second is "photovoltaic + ecological restoration". Ganzi Prefecture is located in the ecological demonstration area in northwest Sichuan, and is an important ecological barrier in western my country, and its strategic position is very important. Aiming at the ecological protection of plateau grassland, the State Power Investment Corporation has tailored a photovoltaic ecosystem that integrates "power generation, water collection, water storage, irrigation, and planting", with the goal of "reducing evaporation, equalizing water sources, conserving soil, and restoring ecology" At that time, cooperate with planting high-quality forage varieties suitable for high-altitude growth in order to achieve the purpose of improving the local ecological environment.

The project will become another important layout of SPIC in the Sichuan-Tibet region. In addition, smart photovoltaics are also a major direction for base demonstrations. The project applies emerging digital technologies, uses smart construction management systems and photovoltaic power plant digital twin production, operation and maintenance management systems, combines technologies such as inverter smart diagnosis, and achieves the goal of "unattended" through remote centralized control, which will expand the ultra-high The altitude photovoltaic project construction scale provides a reference.
