Located in Ganyu District, Lianyungang, this project was the largest flexible‑support fishery‑solar complementary project in China at its initiation stage. It fully adopts five‑cable flexible supports in design, with an AC‑side capacity of 300 MW and a DC‑side capacity of approximately 380 MWp.Developed comprehensively under the “fishery‑solar complementary” model, the project integrates photovoltaic power stations with aquaculture. Photovoltaic arrays are erected above ponds to realize the operating mode of “power generation above‑water and aquaculture below‑water”.
The flexible‑support structural system applied in the project features high strength, reasonable stress distribution and excellent system stability. It boasts strong site adaptability and enables large‑span and high‑clearance layout. An unequal‑span layout is adopted for terrain adaptation. Compared with conventional fixed support solutions, it consumes less material, imposes lower load, allows structural deflection and delivers lower construction cost. It greatly shortens the overall construction period and lifts land‑use efficiency by 20%‑30%.The flexible‑support system entails low‑difficulty construction and exerts minor impact on site soil. The adopted wind‑induced vibration suppression technology guarantees stable and safe operation throughout its 25‑30‑year service life. The project supplies clean and sustainable energy to boost local economy.
Upon completion, the project can supply 449,265.92 MWh of clean electric energy to the power grid annually. It saves approximately 135,902.94 tons of standard coal each year, and cuts emissions of about 371,992.18 tons CO₂, 2,578.79 tons SO₂ and 3,872.67 tons nitrogen oxides. In addition, it substantially reduces annual discharge of ash‑slag, smoke‑dust and wastewater, yielding remarkable energy‑saving and emission‑reduction benefits.
This project employs pre‑stressed high‑strength concrete pipe piles supplied by Pinsheng Building Materials, including models PHC‑500‑100AB and PHC‑400‑95AB with integrated pile tips. Pile lengths range from 8 meters to 14 meters, and the total pile length amounts to 66,895 meters.
