On Wednesday, January 13, Rio Tinto announced that it entered a new agreement with Meridian Energy for electricity supply that would allow New Zealand’s Aluminium Smelter (NZAS) to continue operating at the Tiwai Point aluminium smelter. The agreement is valid till December 31, 2024, meaning a longer certainty to Tiwai employees, local community, and customers and more time for stakeholders to plan the future.

The new agreement with Meridian Energy in relation to power prices is signed just when the New Zealand government was progressing to address the smelter’s high transmission costs. This agreement is expected to make the smelter economically viable and competitive over the next four years. Also, it would provide time for detailed closure studies, allowing stakeholders to undergo extensive consultation with the Southland community.
In July 2020, Rio Tinto announced its decision to wind down operations by August 2021 after a strategic review. The reason was high energy and transmission costs.
Commenting on the new agreement, Rio Tinto Aluminium chief executive Alf Barrios said: “We are pleased to have reached an agreement with Meridian Energy that will enable the Tiwai Point smelter to continue producing some of the lowest carbon aluminium in the world. This agreement improves Tiwai Point’s competitive position and secures the extension of operation to December 2024. It also provides Rio Tinto, the New Zealand government, Meridian, and the Southland community more time to plan for the future and importantly gives our hard-working team at Tiwai and our customers the certainty they deserve.”
New Zealand’s Aluminium Smelter, a joint venture between Rio Tinto (79.36%) and Sumitomo Chemical Co., Ltd. (20.64%), creates around 1000 direct employees and 1600 indirect jobs in Southland.
