In the context of global energy transition and green development, China has taken new steps in the field of clean energy. The first batch of wind and solar projects in the clean energy base in the lower reaches of the Jinsha River have been successfully connected to the grid at full capacity, marking that China has reached a new height in the application and large-scale development of clean energy technology. This milestone not only demonstrates China's technological prowess in the field of new energy development, but also has a profound impact on environmental protection, economic development and energy strategy.
Technical details and scale of the project
The first batch of wind and solar projects in the clean energy base in the lower reaches of the Jinsha River includes 24 photovoltaic power generation projects with a total installed capacity of 2.743 million kilowatts, covering Zhaotong, Chuxiong, Kunming, Qujing and other places in Yunnan. Most of the projects are built and operated by the Three Gorges Corporation, among which the Luofu Laoganshan photovoltaic power station located at an altitude of 2,000-2,200 meters is a typical representative. Designed and constructed by PowerChina Hydropower Bureau 14, the project overcame the technical challenges of high altitude and complex terrain, and fully demonstrated China's ability to develop large-scale photovoltaic power plants under difficult conditions.
The project adopts advanced photovoltaic modules, intelligent operation and maintenance technology, and an integrated development model with multi-energy complementarity. Through the application and optimal design of high-efficiency modules, the power generation efficiency of the project has been significantly improved, which provides a technical reference for similar projects at home and abroad.
Environmental benefits
The grid-connected power generation of the first batch of wind and solar projects plays an important role in environmental protection and emission reduction. According to Zhou Cheng, general manager of the Yunnan branch of the Three Gorges Corporation, the project can generate 3.6 billion kilowatt hours of electricity per year, reducing carbon dioxide emissions by 2.84 million tons per year, which is equivalent to saving 1.12 million tons of standard coal per year.
These data not only highlight the project's role in promoting China's "dual carbon" goals, but also effectively reduce the negative impact of traditional energy on the ecological environment. At the same time, the development of clean energy in high-altitude areas provides China's solution to global climate change governance.

Economic benefits and regional development
The construction of a clean energy base in the lower reaches of the Jinsha River has injected green momentum into regional economic development. During the implementation of the project, it has driven the development of local photovoltaic equipment manufacturing, construction and installation, logistics and transportation. In particular, western regions such as Yunnan have promoted the green transformation of the regional economy and the improvement of social benefits through the development of new energy industries.
In addition, the base adopts the "multi-energy complementary" model to develop wind power and photovoltaic resources, which effectively alleviates the instability of new energy power generation. This technical solution lays the foundation for ensuring the safe and stable operation of the power grid and improving the utilization rate of new energy. In the future, the base will also be supported by digital energy management to form a sustainable ecological chain for the development and utilization of new energy.
Far-reaching implications for the national energy strategy
The Jinsha River Downstream Clean Energy Base is one of the nine clean energy bases focused on in China's 14th Five-Year Plan, reflecting China's strategic intention to optimize the energy structure and promote energy transition.
The overall layout of the base forms the world's largest clean energy corridor along the river with hydropower stations such as Xiluodu, Xiangjiaba, Wudongde and Baihetan. The total installed capacity of the hydropower station is 46.46 million kilowatts, which complements the wind and solar projects and provides strong support for the construction of a new power system based on new energy.
China's clean energy layout represented by this base not only contributes to domestic energy security, but also provides a "Chinese example" for the international energy transition. Through technology export and international cooperation, China's influence in the global energy sector is steadily increasing.
Summary and outlook
The grid-connected power generation of the first batch of wind and solar projects in the clean energy base in the lower reaches of the Jinsha River is a major practice in the field of new energy in China. It not only improves the supply capacity of clean energy, but also provides important support for the realization of the "dual carbon" goal by reducing carbon emissions and promoting the development of green economy.
Looking ahead, with the construction and commissioning of more wind and solar projects, the clean energy base in the lower reaches of the Jinsha River will further strengthen its position in the national energy strategy and become the core force of China's green and low-carbon development.
This project not only demonstrates the potential for technological breakthroughs and industrial synergies, but also shows that China has become an important promoter and leader in the global energy transition.
In the future, the development of the clean energy base in the lower reaches of the Jinsha River will continue to expand new models and technologies, and lead the global new energy industry towards sustainable development in a more efficient and cleaner way.
