NZAS demand overview
NZAS operates the Tiwai aluminum smelter near Bluff. The energy consumed by the smelter is significant and equates to approximately 13% of national demand. On 9 July 2020 NZAS announced plans to close the smelter and that it'd given Meridian Energy notice to terminate the power contract, which will end in August 2021. This dashboard summarises the smelter demand in relation to each region and will track the monthly and dialy demand as the smelter operations wind down.
