Which companies own the Tomago aluminum smelter, and what is Rio Tinto’s ownership stake?

Rio Tinto Group owns slightly more than half of the Tomago smelter; Gove Aluminium Finance Ltd. and Norsk Hydro ASA also hold stakes in the joint venture that operates the plant.

Why is the Australian government providing a bailout to the Tomago smelter, and what did Rio Tinto previously say about its main cost challenge?

The bailout is intended to keep the Tomago smelter operating amid high energy costs, which have severely impacted the power-intensive aluminum industry globally; Rio Tinto previously stated that electricity accounts for more than 40% of Tomago’s operating costs, and had warned that soaring energy costs could force closure when its existing power-supply contract expires later this decade.
