Contact Energy to Supply Power for Rio Tinto's NZ Aluminum Smelter Restart, Boosting Production and Revenue
[SMM Aluminum Express News] Contact Energy has signed a non-binding power supply agreement with Rio Tinto to support the restart of the idle Line 4 potline at the New Zealand Aluminum Smelter in Tiwai Point. The restart would require around 50 MW of additional electricity and add approximately 30,000 tpy of aluminum production, while supporting development of Contact’s Southland Wind Farm. Rio Tinto estimates the project could generate around NZ$100 million annually in additional export revenue for New Zealand.
