Huaneng Group Completes Grid Connection of the First Intertidal Zone PV Power Station in China

PVTIME – December 17, China Huaneng Group Co., Ltd (hereinafter referred to as Huaneng Group or the company), announced that its intertidal zone PV power station, named Qinggang PV power station, has been attached to the grid.

The project is located in the intertidal zone of the sea area near Qinggang Town, Zhejiang Province, China, covering a water area of approximately 1.2 million square meters. The installed capacity of this project is 130MW, with a total of 242,000 photovoltaic modules. The annual power generation of Qinggang PV power station is estimated to be 150 million kilowatt-hours, which is equivalent to saving about 45,000MT of standard coal and reducing carbon dioxide emissions by more than 110,000MT.

Qinggang PV power station is the first project based in the intertidal zone of the tidal flat in China. The project uses independent innovation and patented technology to solve the problem of continuous construction affected by the tide. The project designed with anti-surge, anti-typhoon, anti-corrosion, and anti-sedimentation, ensuring the safety, lowering the cost, and laying the foundation for parity.

During the construction period, Huaneng group paid much attention on ecological protection. The amount of invading aquatic plant Spartina alterniflora was controlled. At the same time, mangroves were planting in the surrounding area restored the natural ecological attributes and functions of the tidal flat.

As its completion, the PV power station became a model of large-scale green development in tidal flats as the project has achieved a three-tier carbon reduction which including high-efficiency power generation in the upper space, biological carbon sequestration in the middle space, and full-scale breeding in the lower space.
