A fishery–photovoltaic integrated project in the Wujiabao subdistrict of Huaiyin district, Jinan, has transformed more than 100 hectares of previously idle fish ponds into a high-tech hub combining clean energy, aquaculture, and rural tourism.

The project, which was fully connected to the grid on March 31, represents an investment of 207 million yuan ($30.37 million). Using a large-span flexible support system, photovoltaic panels are elevated above the water like "aerial corridors", minimizing ground structures and leaving about 60 percent of the ponds available for aquaculture and boat access.

The site is expected to generate 77 million kilowatt-hours of clean electricity annually, reducing carbon dioxide emissions by around 64,000 metric tons. Beneath the panels, the water area has been divided into 184 standardized units for aquaculture, with plans to raise high-value species such as hairy crabs, giant freshwater prawns and Yellow River carp. The project is expected to increase primary industry output by about 7 million yuan each year.

It has also brought tangible benefits to local communities. Three included villages are expected to gain a stable collective income of approximately 2.8 million yuan annually through land leasing, while more than 50 jobs have been created for locals.

Looking ahead, the project aims to expand into tourism and leisure. Plans include fruit orchards, organic vegetable greenhouses and more than 1,000 fishing platforms. By integrating agriculture, renewable energy and tourism, the project offers a model for sustainable rural development.
