**World's Largest Floating Solar Power Plant Launches in China, Marking a Green Energy Milestone**
A few days ago, a reporter from the Global Network Technology learned from the official website of the China Three Gorges Group that on December 10th, the 150MW floating photovoltaic project in Huainan, Anhui Province, officially connected to the grid and started generating electricity. This project is currently recognized as the world’s largest surface-floating solar power plant. As the global solar energy industry continues to expand, this development has also caught the attention of the United States, which has been closely monitoring China’s advancements in renewable energy.
The project is located in the Panji District of Huainan City, an area historically affected by coal mining activities. Over time, the region faced severe environmental challenges, including land subsidence and ecological degradation. Approximately 84,000 mu of land was submerged due to mining, creating significant obstacles for local development. The floating solar project, however, is transforming this problem into an opportunity. By utilizing idle water surfaces in the subsided areas, it shifts the industrial layout from underground to above ground, moving away from traditional "black" energy sources toward a more sustainable "green" future.
Once fully operational, the project is expected to generate around 150 million kWh of clean electricity annually—equivalent to saving about 53,000 tons of standard coal and reducing carbon dioxide emissions by approximately 195,500 tons per year. It can also meet the electricity needs of nearly 94,000 households. Compared to conventional photovoltaic plants, floating solar systems offer additional benefits such as reduced evaporation, algae inhibition, and improved cooling efficiency, leading to higher overall performance.
According to Xiao Fuqin, Deputy General Manager and Chief Engineer at Huainan Sunshine Floating Buoy Technology Co., Ltd., the project uses floating bodies to support over 160,000 solar panels. Each array has a capacity of 3MW, with more than 10,000 panels per unit. Although the initial cost is slightly higher (about 0.3–0.5 yuan per kWh), the increased efficiency of 5–10% makes the project economically viable. Beyond its financial value, the project also plays a crucial role in reshaping international perceptions of China’s green energy strategy.
China Three Gorges Group aims to make this project a model for future floating solar developments, setting new standards for technology and quality. Meanwhile, another groundbreaking innovation in renewable energy is emerging: the world’s first photovoltaic highway. Set to open on the Jinan South Ring Expressway, this road features a load-bearing photovoltaic surface capable of generating electricity while supporting vehicles, paving the way for mobile charging solutions.
Experts like Professor Zhang Hongchao from Tongji University believe that integrating photovoltaic roads with electric vehicle technology could revolutionize transportation, turning highways into “solar charging treasure troves.†With China leading the global solar market, the U.S. has taken notice, launching investigations into Chinese solar imports under Section 201. However, China’s dominance in photovoltaics is undeniable. According to industry leaders, the country now accounts for over 60% of global solar panel production, and its market size has grown rapidly, surpassing even the European market.
While challenges remain, particularly in terms of technological innovation and energy storage, the Chinese photovoltaic industry is entering a period of healthy growth. As the world looks to sustainable energy solutions, China’s efforts in both floating solar and photovoltaic roads signal a bright future for clean energy.
