Putian Nanri Island Project

Location

The project is situated on Nanri Island, Xiuyu, Putian, Fujian Province, China.

Developer and Owner

The project is developed and owned by China Longyuan Power Group Corp Ltd (CLPGC), a subsidiary of China Energy Investment Corporation Ltd.

Project Phases and Capacity

Onshore Component

• The Fujian Putian Nanri Island Wind Farm IV, an onshore component, has a capacity of 49.3 MW and consists of 24 turbines. It was commissioned in 2012.

Offshore Components

• The main offshore wind farm, often referred to as the Fujian Putian Nanridao Offshore wind farm, includes multiple phases. One of the significant phases, Longyuan Putian Nanri Island I, has a total nominal power of 220 MW, but this might be part of a larger complex.
• The overall offshore wind farm in Nanri Island is planned to have a capacity of 400 MW, making it the largest single offshore project in China. This includes various phases and expansions.

Specific 180 MW Phase

While the exact details of a specific 180 MW phase are not explicitly mentioned, it is likely part of the larger 400 MW offshore wind farm development. The project involves several phases, with the total capacity of the offshore wind farm in Nanri Island reaching up to 400 MW.

Technology and Innovation

Deep-Sea Floating Wind Energy

• A recent innovation includes the world's first deep-sea floating wind energy project integrated with aquaculture, located within the National Marine Ranching Demonstration Zone on Nanri Island. This project features three-column semi-submersible floating platforms, each supporting a 4 MW offshore wind turbine, along with solar modules and facilities for fish farming.

Construction Innovations

• The project has pioneered several construction technologies, including the "implanted" rock-socketed single pile foundation construction, which was completed in 2017. This marked a significant breakthrough in offshore wind power construction technology.

Equipment and Turbines

• The offshore turbines are provided by Shanghai Electric Wind Power Group, with recent advancements including the use of ultra-long turbine blades and next-generation half-direct drive offshore turbines like the EW14.0-263 and EW18.0-263 models.

Environmental Impact

• The wind power projects in Nanri Island contribute significantly to reducing carbon emissions. For example, the onshore Fujian Putian Nanri Island Wind Farm IV offsets 90,600 tons of CO2 emissions annually.

Operational and Safety Measures

• The projects undergo rigorous testing and safety measures, including simulation result comparisons, control algorithm development, and extensive operational condition testing to ensure reliability and safety throughout the lifecycle of the project.

Economic and Social Benefits

• The mixed energy project combining wind power, photovoltaics, and aquaculture not only generates electricity but also supports local economic growth through fish farming and other sustainable practices.

In summary, the Putian Nanri Island wind farm is a multifaceted project that includes both onshore and offshore components, with a total planned capacity of up to 400 MW for the offshore segment. It is at the forefront of innovation in wind energy technology and sustainable development practices.
