In the ongoing race for bigger and better, China has temporarily taken a back seat to Siemens Gamesa, a European wind energy company that has just set a new world record with a massive turbine. The company recently installed the gigantic Siemens SG DD-276 turbine in the Østerild test field in Denmark, marking a significant milestone in the wind energy sector.

At an impressive 905 feet (276 meters) from blade tip to blade tip, this turbine is an absolute giant. With a capacity of 21.5 MW, it can power up to 70,000 homes in Denmark annually. Over its expected lifetime, the turbine will prevent approximately 55,454 tons of CO2 emissions that would otherwise be generated by fossil fuel-based power sources.

However, this groundbreaking achievement didn’t come cheap. Siemens Gamesa received a €30 million boost from the European Union’s political union innovation fund as part of the Highly Innovative Prototype of the Most Powerful Offshore Wind (HIPPOW) initiative to help fund the giant turbine. While the Levelized Cost of Energy (LCOE) for this turbine has not yet been disclosed, Denmark's offshore wind energy costs were around €46 per megawatt-hour (MWh) in 2018.

Siemens Gamesa, a leader in the wind turbine industry since 1991, has installed turbines worldwide, including the world’s first offshore wind farm in Vindeby, Denmark. The SG DD-276 marks the company’s 5,000th turbine, contributing to a total capacity of over 27 GW across 14 countries.

China’s Mingyang Smart Energy held the previous record with its MySE18.X 20 MW turbine for roughly seven months before Siemens Gamesa took over. Records in this fast-evolving sector are often short-lived, and Dongfang Electric Corporation had already surpassed this with an 18 MW turbine. Now, Dongfang has announced the completion of a 26 MW turbine that has yet to be installed, while Mingyang is working on its own next-gen 22 MW turbines. Once these turbines are operational, Siemens Gamesa could quickly be overtaken again.

With the ongoing trade tensions and tariffs between the U.S., EU, and China, critical materials like rare earth elements and neodymium—essential for turbine production—could become harder to obtain, as China controls a significant portion of the global supply chain. This could make Siemens Gamesa's wind turbine record short-lived, as supply chain issues may impact future production.
