Primary aluminium smelting energy intensity is reported as AC and DC power used for electrolysis by the Hall-Héroult processes per tonne of aluminium production.
The AC value refers to the power consumed by facilities for the smelting process including rectification from AC to DC and normal smelter auxiliaries (including pollution control equipment) up to the point where the liquid aluminium is tapped from the pots. It excludes power used in casting and carbon plants.
The DC value is a process efficiency metric, measuring the energy intensity of the electrolytic process as the consumption of DC power after rectification per tonne of liquid aluminium is tapped from the pots.

The data presented here is not suitable for life cycle assessment (LCA) purposes, rather data from the IAI life cycle inventory (LCI) reports or from alternative sources, such as regional aluminium assocaitions or life cycle data providers should be used.
The data included in this IAI Statistical Report have been derived from voluntary reports of IAI Member and non-Member companies. Sources outside the industry or estimates are used for “World” and “China” regions only.
The IAI Statistical System is designed to meet the requirement that, in general, individual company data be included only within appropriately aggregated totals by declared geographical areas and not be reported separately. The declared geographical areas and the primary aluminium producing countries which fall in those areas are detailed above.
One asterisk * indicates that the number is revised from previous publication. Two asterisks ** indicates that smelter energy intensity data were not reported to the IAI by the company or companies producing primary aluminium solely within that country; these constitute the estimated part of the “World” average, where data is available. Dates given against a country indicate that data were reported or not reported, as appropriate, for the limited period shown.
The IAI considers the figures shown to be reliable, but they may be subject to revision.
