CGN's 200 MW Ningde Offshore PV Project reached full-capacity grid connection on July 31. The project is one of Fujian Province's first batch of offshore PV projects, and CGN's first offshore PV project co-sited with a nuclear power plant. It stands as a significant model for greening the local energy mix, building a new-type energy system, and helping the region build a zero-carbon demonstration park.

Sited in the maritime area of the Ningde Nuclear Power Station in Beiwan Village, Taimu Mountain Town, Fuding City, Fujian Province, the project makes use of the nuclear base's existing sea-area resources for multi-layered "nuclear-solar complementary" development. It covers about 3,020 mu with an installed capacity of 200 MW and a supporting 20 MW/40 MWh storage system. Over its 25-year operating life, the project is expected to feed roughly 300 million kilowatt-hours into the grid each year, equivalent to cutting standard coal use by about 91,300 tons and carbon dioxide emissions by about 198,000 tons annually.

A 12-kilometer, 220-kilovolt transmission line carries the project power to the grid. Its offshore transmission towers rise 138 meters and is the tallest in eastern Fujian, forming a new green energy landmark along the coast.

"Facing industry-wide challenges like complex nearshore conditions, easily corroded conventional all-steel supports and high construction and O&M costs, we built a pilot platform to test offshore PV monopile support technology to accomplish technical breakthroughs like large-diameter high-performance concrete piles and a innovative lightweight support system. All these has effectively improved the piles' load-bearing capacity and long-term anti-corrosion durability. Also, the overall cost for pile and support construction on the platform has reduced by more than 10%. A replicable and scalable technical approach of nearshore PV construction is established" said Wu Cheng'en, Engineering Management Department Manager at CGN New Energy Fujian Company.

The project achieved the multi-dimensional and intensive use of sea-area resources and charts a path for coordinating nuclear and PV generation. Going forward, CGN will continue building out its "nuclear-wind-solar-storage" model, contributing a "CGN solution" to achieve China's "Dual Carbon Goals" and to the country's new-type energy system.
