New Research Shows U.S. Offshore Wind Could Drive $42 Billion Expansion in Domestic Steel Sector, Supporting 186,600 American Jobs

Five commercial-scale offshore wind projects currently under construction have already sparked tens of billions in domestic supply chain activity, supported thousands of jobs, and are poised to reduce electricity costs for American households. This new analysis shows that offshore wind development over the next two decades could generate $42 billion in demand for U.S. steel, including tower, foundation, and vessel components, supporting more than 186,000 American jobs across mills, fabrication yards, shipyards, and supplier industries. This potential growth comes as U.S. steel mills have already invested more than $3 billion in upgrades to expand plate‑steel production capacity in Kentucky, Ohio, and Texas, positioning American mills to meet up to 80% of domestic demand for offshore wind-grade steel. 

“This research makes clear that offshore wind is not just an energy opportunity — it is an American industrial strategy,” said Liz Burdock, President & CEO of Oceantic Network. “By driving $42 billion in steel demand, a 22% increase from our nation’s energy sector, offshore wind gives U.S. steel mills the long-term, predictable orders they need while strengthening our steelmaking base, revitalizing shipbuilding, and anchoring thousands of durable, family‑sustaining jobs in communities across the country. When we expand our offshore energy generation, we secure investments here at home, lower energy costs, enhance grid reliability, and ultimately improve the quality of life for all Americans. Offshore wind is proving that U.S. workers and U.S. manufacturers can lead the next chapter of our energy economy—if we choose to seize it.” 

Offshore wind is entering a pivotal phase of U.S. energy expansion. A growing fleet of domestic projects—combined with a 40-state U.S. supply chain—provides an unprecedented opportunity to rebuild industrial capacity, revitalize legacy steel communities, and reduce reliance on foreign energy and suppliers. The study shows that a homegrown offshore wind supply chain is no longer hypothetical—it exists and is laying the groundwork for rapid scaling.  

The research quantifies steel demand for 70 GW of leased and proposed American offshore wind projects and matches that demand to existing and planned U.S. steel mill and fabrication infrastructure, identifying critical opportunities for policymakers and suppliers to capture long-term economic benefits. Rather than a dependence on overseas supply chains, steel mills in Kentucky and Ohio can drive new economic activity into the Gulf, Carolinas, and other seaboard communities hosting fabrication sites. Turning opportunity into reality, however, requires consistent demand for finished products––towers, monopile foundations, vessels––and attracting the investments needed for new factories requires industry stability. These gains hinge on restoring a predictable energy permitting pathway. 

KEY FINDINGS: 

• $42 billion in potential U.S. steel demand over the next two decades.  

• 186,600 American jobs supported across steel mills, fabrication facilities, shipyards, and suppliers—averaging 9,300 jobs per year over 20 years.  

• 22 million tons of steel required, equivalent to 239 Golden Gate Bridges or 266 Empire State Buildings. 

• Recent U.S. mill upgrades enable 80% of required plate steel to be produced domestically. 

• With targeted investments, U.S. fabrication yards could meet 78% of demand for towers, foundations, and transition pieces. 

• Without domestic fabrication expansion, the U.S. would capture less than 10% of the opportunity, stranding current mill investments and reinforcing reliance on overseas supply chains. 

• Offshore wind development already accounts for $25 billion in U.S. investments and tens of thousands of jobs across 40 states. 

This opportunity extends far beyond wind farm components. Long-term, large‑volume steel demand from offshore wind finances capital expansion at American mills, restores rare manufacturing capabilities, strengthens supply lines for naval vessels, hydropower, nuclear facilities, bridges, and other critical infrastructure, and anchors career‑length, blue‑collar employment in industrial communities.
