“Those Blades Dwarf the Great Pyramid”: Dongfang Electric’s 502-Foot Wind Turbine Shocks Experts as China Aims to Power 40,000 Homes With a Single Giant

The advent of ultra-long wind turbine blades represents a significant milestone in renewable energy technology. These blades, towering over iconic structures like the Great Pyramid and the Washington Monument, are set to revolutionize offshore wind energy. Shipped from Yantai, China, these 502-foot-long blades will be installed on the world’s most powerful offshore wind turbine. This development is part of Dongfang Electric Corporation’s ambitious push to lead in the offshore wind sector. As these blades undergo final testing, the global energy community watches closely, anticipating the transformative impact on energy production and sustainability.

Dongfang Electric’s Strategic Leap in Offshore Wind

Historically, Dongfang Electric has not been a dominant player in China’s offshore wind industry. However, the company is now taking decisive steps to change this narrative. By focusing on large-scale, high-capacity wind turbines, Dongfang is positioning itself as a significant contender. The company has adopted a transparent approach, regularly updating the public on its testing progress. This includes sharing images from static tests, adhering to international standards such as IEC 61400-23.

The size of these blades is noteworthy, standing three meters taller than the Great Pyramid of Giza. They also rival the height of the Washington Monument and St. Paul’s Cathedral. Previously, the longest blade was 482 feet, developed by Sinoma for Goldwind. Dongfang is now set to break this record, underscoring its commitment to innovation. The rapid development of its 26 MW platform, along with a 17 MW floating offshore turbine, highlights Dongfang’s strategic intent to scale up swiftly and effectively.

Engineering Marvel: Size and Power

The 26 MW wind turbine, upon completion, is projected to generate approximately 68 million kilowatt-hours (kWh) of clean electricity annually. This output could power nearly 40,000 homes, contributing significantly to China’s renewable energy objectives. Recently, Dongfang partnered with China Huaneng Group to introduce the world’s most powerful direct-drive floating wind turbine.

This 17 MW turbine, produced in Fuqing, Fujian Province, stands 498 feet tall with a rotor diameter of 859 feet. The turbine’s sweeping area covers 53,000 square meters, equivalent to about 7.5 soccer fields. Such engineering feats reflect the scale and ambition of Dongfang’s renewable energy projects. These advancements not only showcase engineering prowess but also underscore the potential for substantial contributions to global sustainability goals.
