The Nordex Group announced on December 10, 2025, that it has been awarded significant contracts by Alliant Energy following a rigorous and competitive RFP process. The agreement will see Nordex supply up to 190 turbines of the N133 and N163 Delta4000 Variants for large-scale projects in the Midwest, including Iowa, pending regulatory approvals.

Project Specifications and Timeline

The turbine installation is scheduled for 2028 and 2029, with the wind energy systems providing up to 1,060 megawatts (MW) of capacity once installed and operational. The turbines will be manufactured at Nordex's facility in West Branch, Iowa, where the company recently restarted production of turbine hubs, drivetrains, and nacelles.

The agreements will become effective upon the required regulatory approvals and do not yet constitute a firm order. Antonio Smyth, Executive Vice President of Power Generation and Gas Strategy at Alliant Energy, noted that upon approval from the Iowa Utilities Commission, the company looks forward to building these projects, benefiting customers for years to come.

Economic Impact and Manufacturing Investment

The contracts represent a major investment in Iowa manufacturing, resulting in job creation while spurring economic development across the region. Lisa Barton, President and Chief Executive Officer of Alliant Energy, stated that choosing Nordex underscores their confidence in the company's capabilities and their commitment to partnering with companies that support their ability to serve customers and communities.

She emphasized that the decision to select a local provider promotes substantial economic development opportunities throughout their service area and enables them to meet increasing energy demand efficiently.

Manav Sharma, CEO of Nordex North America, expressed gratitude to Kim Reynolds, Governor of Iowa, and the Iowa Economic Development Authority for their outstanding support. He noted that Governor Reynolds has been a great sponsor of local manufacturing, with a focus on bringing more manufacturing jobs to Iowa.

Strategic Significance for Both Companies

For Nordex, this contract represents a significant milestone in the company's U.S. operations. José Luis Blanco, CEO of the Nordex Group, described the award as the largest-volume award in the company's 25-year history in the United States. He stated that this affirms their strategic decision to restart production in Iowa, underscores their commitment to the U.S. market, and drives regional economic development while supporting progress towards their mid-term target.

Smyth explained that, as part of Alliant Energy's rigorous supplier selection process, Nordex demonstrated its advanced technology, supply chain discipline, and ability to successfully execute these projects while providing added value through local turbine manufacturing in Iowa. The agreement positions Alliant Energy to manage its resource strategy while delivering outstanding value to customers.
