Aug 11, 2026 Alunorte Cuts Alumina Output To 50% On Natural Gas Supply Shortage Neutral

🤖 AI Overview

What happened: Norwegian aluminum producer Norsk Hydro's Alunorte plant in Brazil, one of the world's largest alumina refineries, reduced output by 50% on March 14, 2023, due to disruptions in natural gas supply. The plant, which accounts for around 10% of global alumina production, cut production to 50% of its 6.35 million metric tons per year capacity.

Market impact: The aluminum industry is facing supply disruptions, driving up alumina prices. Alunorte's reduced output tightens the global alumina market, benefiting other producers like Rio Tinto and Aluminum Corporation of China. However, it also raises concerns about potential aluminum shortages and increased production costs for downstream industries like automotive and packaging.

What to watch next: On April 25, 2023, Norsk Hydro reports its Q1 earnings, which will provide insights into the financial impact of the gas supply disruptions. Additionally, monitor the resolution of the gas supply issue at Alunorte, with a potential restart of full operations. Lastly, keep an eye on global alumina prices, which could remain elevated due to the reduced supply from Alunorte.
