AEMO media statement – forecast LOR1

AEMO has issued a forecast LOR1 condition in Queensland from 5pm to 7:30pm today, with more than 793 megawatts of reserves available at that time. This is a forecast only at this stage and may not materialise. 

At this level (LOR1), there is no immediate impact to power system security or reliability. However, AEMO continues to monitor the situation following the loss of generation units at the Callide C Power Station in Central Queensland yesterday afternoon.

LOR1 market notice signals a reduction in pre-determined electricity reserve levels, encouraging generators to offer more supply, or large industrial or commercial consumers to reduce their demand. 

Last night, AEMO 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, the LOR conditions were cleared.

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