The US steel crunch puts solar deployment plans at risk, creating delays, raising costs, and threatening America’s renewable energy transition. Steel, the backbone of solar projects, is in short supply due to global supply chain disruptions, rising domestic demand, and restrictive trade policies.
Without urgent solutions—such as expanding domestic green steel production, recycling, and better trade coordination—the US risks falling behind on its 2030 clean energy targets.
Introduction: Why the US Steel Crunch Matters
The US steel crunch puts solar deployment plans at risk, a challenge that policymakers, developers, and investors are struggling to resolve. Solar energy is expected to play a central role in the US clean energy mix, with the US Department of Energy (DOE) projecting solar could provide 40% of electricity by 2035.
But steel shortages are raising solar project costs by 15–20%, delaying construction, and discouraging investment.
Causes of the US Steel Crunch
1. Supply Chain Disruptions
- COVID-19 disrupted shipping and steel supply networks.
- Russia-Ukraine war restricted steel exports, particularly for construction-grade steel.
2. Rising Domestic Demand
- Federal infrastructure projects, EV plants, and data centers are consuming record amounts of steel.
- Competing industries leave less supply for solar developers.
3. Trade Policies and Tariffs
- Section 232 tariffs on Chinese steel remain in place.
- Import quotas from South Korea, Brazil, and Mexico limit alternatives.

Impact on Solar Deployment
- Delays: More than 25 GW of solar projects could face construction delays in 2025.
- Cost Inflation: Steel accounts for 12–15% of solar costs; shortages add millions to project budgets.
- Investor Risks: Shrinking profit margins discourage financing.
Case Study: Texas Utility-Scale Solar Farm
A 500 MW solar project in Texas was delayed by eight months because mounting steel structures were unavailable. Developers switched to aluminum but faced an extra $120 million in costs.
Expert Commentary
- “The steel crunch could reduce US solar deployment capacity by 15–20% over the next two years.” — BloombergNEF Analyst
- “Steel is as essential to solar as silicon is to solar panels.” — CEO, Solar Energy Industries Association (SEIA)
Broader Implications for Renewable Energy Goals
- US 2030 Target: 100% clean power by 2030 may be delayed by 3–5 years if bottlenecks continue.
- Annual Capacity: New solar installations may fall from 40 GW to 30 GW annually.
- Climate Targets: Higher costs could slow net-zero progress.
Possible Solutions
1. Domestic Green Steel Expansion
- Companies like Nucor and US Steel are investing in low-carbon electric arc furnaces (EAFs).
- New plants could add 10–15% more capacity by 2027.
2. Alternative Materials
- Aluminum and composites are being piloted as substitutes.
- Current challenge: higher prices and weaker durability for large farms.
3. Recycling Scrap Steel
- Recycled steel could cover 25% of solar industry needs, reducing imports.
- Circular economy practices help cut emissions too.
4. Policy Adjustments
- Relaxing import quotas and providing incentives for green steel R&D.
- Closer supply coordination with allies like Canada, Mexico, and India.

Global Steel and Solar Context
- Europe: EU’s CBAM is adding carbon costs to steel imports, driving up global prices.
- China: The world’s top steel exporter, but reducing output for climate targets.
- India: Expanding exports, with potential to supply US solar developers.
Financial Outlook
- Steel Prices: Expected to stay high at $850–900/ton through 2025.
- Solar Costs: Levelized cost of electricity (LCOE) could rise by 5–7%.
- Investments: Higher capex may deter smaller solar firms.
Frequently Asked Questions (FAQ)
Q1: Why does steel matter so much for solar projects?
Steel is used in mounting structures, frames, and tracking systems.
Q2: How much of solar project costs come from steel?
Roughly 12–15% of total project costs.
Q3: Are alternatives to steel viable?
Aluminum and composites are options, but currently more expensive.
Q4: How will this impact US solar goals?
Capacity additions may slow by 20%, delaying 2030 renewable targets.
Q5: What can policymakers do?
Encourage domestic green steel production, incentivize recycling, and adjust tariffs.
Conclusion
The US steel crunch puts solar deployment plans at risk, making it one of the most urgent barriers to renewable energy expansion. Without solutions, the US may face slower progress toward climate goals.
Expanding domestic green steel, investing in recycling, and adjusting trade policies will be critical to ensuring that solar remains the fastest-growing renewable energy source in the country.
