America’s Big New Aluminum Smelter Is Still Waiting on a Power Deal

Why It Matters

Securing affordable, long‑term electricity is essential for reviving U.S. aluminum manufacturing and reducing reliance on volatile imports, directly affecting industrial competitiveness and energy policy.

Key Takeaways

• $4 billion Oklahoma smelter could double U.S. primary aluminum capacity
• Project needs over 11 TWh annually, equivalent to Boston’s power use
• Construction slated for late 2026; production expected by 2030
• Securing a long‑term power deal with AEP subsidiary remains critical
• Energy competition from data centers and EVs threatens smelter’s cost viability

Pulse Analysis

The aluminum market is at a crossroads as geopolitical tensions in the Middle East have throttled supply from Gulf producers, driving up global prices and exposing the United States’ heavy reliance on imports. With Iran’s recent attacks on key Gulf smelters and a prolonged Strait of Hormuz blockade, domestic manufacturers are scrambling for alternatives. The Oklahoma Primary Aluminum joint venture, backed by Emirates Global Aluminium and Century Aluminum, represents a strategic response, aiming to inject 750,000 metric tons of primary aluminum annually and more than double the nation’s existing capacity.

At the heart of the project’s feasibility is electricity. Aluminum smelting consumes roughly 13‑15 MWh per ton, meaning the Oklahoma plant will need over 11 terawatt‑hours each year—enough to power a midsize U.S. city. Developers are negotiating a long‑term power purchase agreement with Public Service Company of Oklahoma, an AEP subsidiary, while also eyeing a mix of natural‑gas, wind, and solar to meet decarbonization goals. The utility’s ability to deliver reliable, cost‑effective power will determine whether the plant can meet its construction timeline and remain competitive against data centers and electric‑vehicle charging networks that are also vying for limited grid capacity.

Beyond the immediate economics, the smelter underscores a broader policy dilemma. While recent tariffs have shielded some domestic producers, they do not address the fundamental energy cost challenge that has driven U.S. capacity down from 33 plants in 1980 to just four today. Federal incentives, such as the $500 million DOE grant and state‑level power discounts, signal a willingness to support large‑scale manufacturing, yet sustained progress will require systematic reforms to expand affordable, low‑carbon electricity. If those reforms materialize, the Oklahoma project could serve as a blueprint for a new wave of U.S. smelters, bolstering supply security and fostering a greener industrial base.
