China Huaneng Group Co., Ltd. Yuhuan Power Plant built China's first intertidal photovoltaic power station—Qinggang Photovoltaic Power Station to generate electricity with full capacity.

The project is located in the intertidal zone of the sea area near Qinggang Town, Yuhuan City, Zhejiang Province, with an installed capacity of 130,000 kilowatts, covering a water area of approximately 1.2 million square meters, and installing a total of 242,000 photovoltaic modules. The estimated annual power generation capacity is 150 million kWh, which is equivalent It saves about 45,000 tons of standard coal each year and reduces carbon dioxide emissions by more than 110,000 tons.

For the first time, the project realized the construction of photovoltaics in the intertidal zone of the tidal flat. Zhejiang Branch and Yuhuan Power Plant aimed at the location bottleneck of the muddy intertidal zone in the southeast coast, creatively proposed a full-time construction plan for the full cofferdam, and built a 10-km-long Huaneng “ecological cofferdam” with independent innovation and patented technology. "The method of sub-block cofferdam water storage and sub-division implementation solves the problem of continuous construction affected by the tide and improves transportation efficiency. The project has repeatedly demonstrated the problems of anti-surge, anti-typhoon, anti-corrosion, anti-settlement, and fully optimized the selection of pile foundation and the layout of photovoltaic modules, which not only improved the safety factor, but also effectively controlled the cost, laying the foundation for parity.

During the construction period, Huaneng attaches great importance to ecological protection. In response to the invading aquatic plant Spartina alterniflora on the original beach of the beach, a special plan was formulated to simultaneously carry out ecological management. The upper structure of the project adopts the process of installing photovoltaic panels on the support, and the lower structure adopts the form of pile foundation of permeable structures, which does not change the natural attributes of the sea area. At the same time, mangroves are planted around to restore the natural ecological attributes and functions of the beach.

After its completion, the power station has achieved a three-tier three-dimensional carbon reduction with high-efficiency power generation in the upper space, biological carbon sequestration in the middle space, and full-scale farming in the lower space. Demonstration of large-scale green development of tidal flats.
