Norsk Hydro's Alunorte Restores Full Alumina Production After Gas Supply Disruption
Event summary
- Alunorte alumina refinery resumes full production after securing temporary gas supply agreement with CELBA.
- Production was reduced due to natural gas availability disruptions, resulting in lost output of 100,000–120,000 tonnes.
- Q3 2026 financial impact estimated at USD 75–100 million from reduced production and higher gas costs.
- ANP approved Norsk Hydro as self-importer of gas to mitigate supply risks.
The big picture
This incident highlights the vulnerability of energy-intensive industries to supply chain disruptions, particularly in regions with constrained gas infrastructure. Norsk Hydro's ability to navigate this challenge will be closely watched as a test case for operational resilience in commodity markets. The financial impact underscores the need for diversified energy sourcing strategies in alumina refining.
