AEMO media statement

The Australian Energy Market Operator (AEMO) has confirmed that through a combination of maximising interconnector flows from New South Wales into Queensland, a number of generators returning to service and Queenslanders reducing their electricity consumption – all lack of reserve conditions have now cleared.

Significant collaboration across the energy sector, assisted by consumers, avoided further disruption to Queensland homes and businesses.

AEMO CEO Daniel Westerman thanked the Queensland Government, Energy Queensland, Powerlink, and all of the generators that maximised their availability and collectively ensured impacts to customers were minimised, following a major event at the Callide C power station.

“Queenslanders played a significant role in managing the situation – both through their rooftop solar systems, and by acting on calls to voluntarily reduce their electricity usage where safe to do so,” he said.

“We can be grateful there were no injuries at Callide, and work is now underway to ensure the safe restoration of generation at the site.”

AEMO will issue a further update and an initial incident review in due course.
