On December 22, China’s largest aqua-PV project—the 1.09 million kW Haitang PV Power Station in Hebei Province by CHN Energy’s Guohua Energy Investment Co., Ltd.—successfully connected to the grid. This achievement marks a significant milestone in the high-quality and large-scale development of renewable energy in China.

Haitang PV Power Station in Hebei Province

Located in Cangzhou City, Hebei Province, along the Bohai Sea coastline, the project is part of China’s third batch of large-scale wind and PV base projects, with a total investment of approximately 6.5 billion RMB. The facility consists of 363 PV arrays, with 2.31 million solar panels installed, covering an area of about 1734.2 hectares. The project takes advantage of Cangzhou’s unique natural resources and its strong aquaculture industry to develop and apply key technologies for the aqua-PV green ecological farming model, establishing an innovative technological system for this approach.

Once fully operational, the power station is expected to generate an average of 1.86 billion kWh of electricity annually, enough to meet the electricity needs of approximately 2.79 million residents. Additionally, the project is expected to produce over 100,000 kilograms of fish and shrimp each year, save around 561,000 tons of standard coal, and reduce carbon dioxide emissions by approximately 1.4 million tons. These benefits will bring significant economic returns and play a crucial role in supporting the region’s transition to a renewable energy-based power system.

Furthermore, the project will integrate Cangzhou’s abundant onshore renewable resources, along with its port and chemical industry applications, to establish a large-scale renewable energy base with a total capacity of one million kilowatts. It will also include the construction of a green hydrogen and ammonia facility with an annual production capacity of 50,000 tons, along with the necessary green hydrogen infrastructure. This initiative aims to establish China’s first coastal green ammonia integrated application project, promoting the development of a hydrogen-based green energy and green port system in Cangzhou.
