China Connects World’s Largest Offshore Wind Turbine to Grid

Envision Energy has successfully connected the world’s largest offshore wind turbine, the EN-256/16.7 prototype, to the grid in Sheyang, China. This achievement marks a significant milestone in China’s offshore wind power industry, positioning it at the forefront of global technological advancements.

The EN-256/16.7 is not only the largest wind turbine in the world but also the first “carbon neutral” offshore large-megawatt wind turbine in China.Building on the foundation of the EN-252/14 model, the EN-256/16.7 enhances technological innovation in various aspects such as manufacturing, delivery, hoisting, and maintenance.

This turbine is designed to perform optimally in the challenging conditions of deep-sea environments, with core components like blades, gearboxes, and electrical systems passing rigorous type certification tests.

Envision’s comprehensive offshore wind turbine supply network spans across China’s coastal waters, with production facilities capable of nearly 10GW. This network supports the delivery of large wind turbines to markets with varying wind speeds across Guangdong, Zhejiang, Guangxi, Jiangsu, and Shandong.

The success of the CGN Huizhou project, utilizing 19 Envision turbines including the EN-252/14 and EN-226/8.5 models, underscores the reliability and performance of Envision’s large offshore wind turbines. These turbines have operated stably for over six months, demonstrating their robust delivery capabilities.

Addressing the challenges posed by deep-sea scenarios, Envision has developed innovative solutions for the transportation, hoisting, and maintenance of large wind turbines. The modular design of their turbines allows for the easy replacement of components, reducing offshore operation time and improving efficiency. Envision’s self-developed single-blade horizontal replacement hoist further facilitates the maintenance of large-scale blades, even under adverse conditions such as typhoons.

In January 2024, the EN-256/16.7 unit rolled off the production line at the Sheyang Zero Carbon Industrial Park, showcasing Envision’s commitment to low-carbon materials, intelligent design, and zero-carbon manufacturing. This groundbreaking turbine, now connected to the grid, represents a significant step towards achieving China’s dual-carbon goals and highlights Envision’s leadership in the offshore wind power industry.
