Rio Tinto is expanding its aluminum production in Quebec with a 1.5 billion dollar investment in a low-carbon smelter. This project aims to reduce the carbon footprint of aluminum production by utilizing Quebec's hydroelectric power grid. The expansion focuses on scaling the production of low-carbon aluminum to meet growing global demand for sustainable industrial materials. This move highlights the shift toward electrified smelting processes to replace high-emission energy sources.

Quebec has the hydro capacity, but I wonder about the actual interconnection timeline for this expansion. Adding a smelter is a massive load hit. Did they specify if this requires new transmission lines or if they are using existing headroom?
The real question is how they are accounting for the carbon. If they are just claiming low carbon because of the grid, that is standard. I want to see if there are specific procurement rules or green premiums attached to this specific output.
1.5 billion is a lot of capital. It would be interesting to see the efficiency gains per ton compared to their older pots. Usually, the biggest wins in these expansions come from better heat recovery and newer pot liner tech.
True. It is a big bet on the demand for green aluminum. If the market actually pays a premium for low carbon metal, this pays off. If not, it is just a very expensive way to make the same product.
