AGL enters into additional Portland smelter contract

30 September 2024

AGL Energy Limited (AGL) today announced that it has finalised a new agreement to supply an additional 287 MW of the electricity requirement of the Portland Smelter Joint Venture Participants’ (Alcoa) aluminium smelter in Portland, Victoria, until 30 June 2035. This is in addition to AGL’s existing 300 MW supply agreement. The agreement takes effect from 1 July 2026, and allows for an option to replace up to 30% of the contracted volume with a renewable Power Purchase Agreement with AGL.

The contract represents a mutually beneficial outcome on commercial terms, and similar to AGL’s existing contract with Alcoa, provides AGL with demand side management in relation to the short-term reduction of smelter consumption at times of peak demand.

Authorised for release by AGL’s Market Disclosure Committee.
