Alcoa Corp's <AA.N> Australian aluminium smelter was hit by a power cut on Friday after a transmission line tripped amid soaring temperatures in the country's southeast, the Australian Energy Market Operator said.
AEMO, which manages electricity supply, said the transmission line outage "has resulted in a separation between Victoria and South Australia at the Heywood Interconnector, as well as interrupting supply at the Portland aluminium smelter."
"At approximately 2:20 p.m. EST on 31 January, Portland Aluminium smelter lost power to both potlines due to a fault external to the plant. The cause of the fault is currently unknown," an Alcoa spokeswoman said in emailed comments.
