The Nordex Group will supply Alliant Energy with up to 190 wind turbines for large-scale projects in the Midwest, including Iowa, following a competitive request for proposals process.
The turbines, consisting of N133 and N163 Delta4000 variants, are scheduled for installation in 2028 and 2029. Once operational, they will provide up to 1,060 megawatts of capacity.
Subject to regulatory approval from the Iowa Utilities Commission, the turbines will be manufactured at Nordex’s facility in West Branch, where the company recently restarted production for turbine hubs, drivetrains and nacelles.
“Choosing Nordex underscores our confidence in their skills and our commitment to working with partners who support our ability to serve our customers and communities, and we are pleased to have selected a local provider for this work,” said Lisa Barton, president and chief executive officer of Alliant Energy, in a release. “This decision also promotes substantial economic development opportunities throughout our service area and enables us to efficiently meet the increasing energy demand.”
Antonio Smyth, executive vice president of power generation and gas strategy at Alliant Energy, said Nordex demonstrated advanced technology, supply chain discipline and project execution capability during the supplier selection process.
The agreements will become effective following required regulatory approvals and do not yet represent a firm order.
“Upon approval from the Iowa Utilities Commission, we look forward to building these projects, benefiting our customers for years to come,” Mr. Smyth said.
Manav Sharma, CEO of Nordex North America, said the company was proud to work with Alliant Energy on the projects.
José Luis Blanco, CEO of the Nordex Group, said the contracts represent the largest volume awarded in the company’s 25-year history in the United States.
Alliant Energy provides regulated energy service to approximately 1 million electric and 430,000 natural gas customers across Iowa and Wisconsin through its two public energy companies, Interstate Power and Light Company and Wisconsin Power and Light Company.
The Nordex Group has installed around 57 gigawatts of wind power capacity in over 40 markets and generated consolidated sales of around 7.3 billion euros in 2024. The company has more than 10,400 employees with manufacturing facilities in Germany, Spain, Brazil, India and the United States.
