Industry advocates argue that the revival of U.S. aluminum production depends more on affordable power than on protectionist tariffs, according to Mining.com. Century Aluminum's proposed smelter in Oklahoma remains contingent on securing a long-term electricity agreement, a critical hurdle for restarting domestic capacity.
Without a stable, cost-effective power supply, planned smelter projects face delays or cancellation. Century Aluminum has not disclosed specific power purchase terms, but the company requires a multi-year deal to underpin capital investment. The U.S. currently recycles roughly 70% of its scrap, but primary smelting capacity has dwindled to just a fraction of peak levels.
Infrastructure constraints compound the challenge. Bringing a new smelter online demands dedicated transmission lines and substation upgrades, often requiring years of permitting and construction. Century Aluminum's project, if realized, could supply a significant portion of domestic auto and aerospace demand, but the lack of a power agreement stalls any timeline.
Geopolitical dynamics add pressure. U.S. tariffs on imported aluminum aim to boost domestic output, yet high energy costs undercut competitiveness. Canadian hydro-powered smelters, by contrast, operate at lower marginal costs, highlighting America's structural disadvantage. Trade routes and sanctions on Russian metal further complicate global supply chains.
The power hurdle underscores a broader energy transition tension. As renewables scale, legacy industries face uncertain grid access. Advocates say that without policy support for baseload power allocation, even tariff-protected smelters will struggle to attract capital.
