Alcoa Corp will need cheaper, more reliable power to keep its Portland smelter in Australia open beyond 2021 when its current supply deal ends, the aluminium major’s partner said on Thursday.
Alumina Ltd, Alcoa’s partner in the Alcoa World Alumina and Chemical joint venture, would have a veto over any decision to shut the plant, its Chief Executive Mike Ferraro said, adding it was too early to predict the smelter’s future.
