TOMAGO KEEPS THE LIGHTS ON ACROSS THE STATE

The bushfires recently caused a severe short-term energy shortage and Tomago Aluminium was able to immediately respond by shutting down two potlines to avoid blackouts across the state. 

Whilst this is always risky with no guarantee that they can be restarted, its preferable to risking the grid collapsing.

The plant is now back to full capacity and our actions helped to maintain the stability of the electricity grid.

Tomago Aluminium is the country’s largest electricity consumer and takes a constant 950MW or 10% of NSW supply. It is also the largest "interruptible" load and can take around 600MW off the state grid within minutes.

In cooperation with AGL Energy, Tomago was able to reduce its load by cycling two potlines through a carefully controlled curtailment.

This curtailment process is part of the energy supply contract that has been in place since November 2017 and runs through to 2028.

This is the first time this year that we have had to switch off potlines and we don’t expect it to be the last with the end of summer still a long way off. 

Thank you to all site personnel who assisted on the day; all emergency response plans were followed and there were no injuries or equipment damage.

Overall a great outcome by all, well-done everyone.
