The entire world is gradually transitioning to renewable energy for a single mission: achieving net-zero by 2050. However, that does not mean competition isn’t fierce to build some of the finest renewable technologies ever known. America has created a 140-meter giant wind turbine that could redefine wind power. China could soon lose its title of having the tallest wind turbines.

The creators behind the powerful giants

A $16 billion American business is breaking ground in the renewable industry. GE Renewable Energy has one of the most diverse portfolios when it comes to renewables, and has over 400 GW of clean renewable energy installed, with over 90% of utilities equipped with its power solutions across the world. Their purpose? To supply consumers with solutions for reliable and cost-effective clean power.

One of the company’s powerful giants is the 3.0-3.4 MW Sierra wind turbine. The Sierra has a 140-meter rotor with a variety of hub heights to choose from, including a height New Atlas, China is known for having the largest onshore wind turbine in the world, but this turbine could give China a run for its money. It also sports GE’s pioneering two-piece blade design that enhances installation, transport, and maintenance. The Sierra has received over 1 GW of orders, including a big shot in renewable research.

Creating a bigger wind turbine for a bigger picture

When it comes to sustainable energy, it is crucial to always look at the bigger picture, whether it be giant onshore or giant offshore wind turbines. This is where the National Renewable Energy Laboratory’s (NREL’s) Flatirons Campus comes in. The NREL is home to a variety of research assets to model and validate the technology.

The NREL will be researching traditional turbines and wind farms on behalf of the US Department of Energy’s (DOE’s) Wind Energy Technologies Office. The 3.4 MW Sierra turbine will be at the center of the research and supplement the current DOE 1.5 MW turbine. The Sierra’s construction will commence in Spring 2026. According to Mike Derby, DOE’s wind technology program manager, Sierra has great features, including:

  • The two-piece blade enables researchers to easily swap out the tips with NREL’s tips created in the Composites Manufacturing Education and Technology Facility (CoMET)
  • Adding two transformers with varying voltage output levels, as requested by WETO and some NREL grid integration researchers
  • A partnership with GE Vernova’s Advanced Research Center, which has equal research priorities

“It’s a benefit that we can leverage NREL’s resources to do research on future technologies. Whether that be interfacing with NREL’s hydrogen or battery storage or working on turbine technology development on the mechanical side.” – Greg Cooper, external partnerships manager for GE Vernova’s onshore wind division

Bigger is better when it comes to research

Sierra will also be added to research on the Advanced Research on Integrated Energy Systems (ARIES) platform, which integrates numerous renewable technologies with model grid scenarios. According to the NREL official website, Sierra will be integrated with real and virtual assets to research, validate, and demonstrate real industry challenges.

“Together with the ARIES platform, hydrogen production, and the grid simulator, it makes for a really nice suite of capabilities that the new turbine’s going to enhance.” – Derby

Sierra will also play a role in the direct and indirect electrification of industrial process investigations. This could indicate potential advantages of renewable-energy-driven microgrids to generate affordable hydrogen for industrial applications. It also has the potential to provide DC power, enabling researchers to investigate the advantages of direct power production for industrial processes or close coupling with electrolyzers.

GE Renewable Energy’s Sierra turbine has its work cut out for it. Whatever its use will be in the end, its role in research to enhance future applications of wind power and its potential impact is vital.
