CNECC(SH:601611) Xin Hua She·2025-10-31 03:20Core Viewpoint - The successful grid connection of a 26 MW offshore wind turbine in Dongying, Shandong Province marks a significant advancement in clean energy generation and showcases China's capabilities in wind power technology [1][2]. Group 1: Technological Achievements - The wind turbine, developed by Dongfang Electric Group, sets two world records for single unit capacity and rotor diameter among grid-connected wind turbines [2]. - The rotor diameter exceeds 310 meters, with a swept area equivalent to 10.5 standard football fields, and the hub height surpasses that of a 50-story building [2]. Group 2: Energy Production and Environmental Impact - Under full load operation, the turbine can generate 62 kWh of electricity per rotation, with an annual output of up to 100 million kWh at an average wind speed of 10 m/s, sufficient to power 55,000 households for a year [2]. - This production equates to a reduction of 30,000 tons of standard coal consumption and an 80,000-ton decrease in carbon dioxide emissions annually [2]. Group 3: Infrastructure and Industry Development - The Dongying Wind Power Equipment Testing and Certification Innovation Base, operational since May, features 12 high-capacity wind testing positions and a comprehensive testing system, addressing long-standing industry challenges of certification difficulties, lengthy cycles, and high costs [2]. - The base currently hosts five of the top ten domestic wind turbine manufacturers and four accredited testing organizations [2].
