Despite there being sufficient physical generation capacity in Queensland today, AEMO is taking steps to address a critical electricity supply shortfall presently forecast for 6pm to 8pm (AEST) today.
Yesterday (12 June), electricity prices in Queensland reached a cumulative high price threshold of $1,359,100 (accumulated over seven days), triggering an administered price cap of $300/MWh under the National Electricity Law and the National Electricity Rules.
As a consequence, available offers from generators reduced, contributing to a forecast supply shortfall.
To maintain power system security and reliability, AEMO is using its powers under the National Electricity Rules, including to direct generators, to alleviate lack of reserve conditions.
At this stage, these efforts have provided sufficient generation to cover the lack of reserve 3 shortfall.
The cumulative high price threshold is forecast to be exceeded in some other NEM regions this evening.
AEMO will continue to monitor reserve conditions closely in Queensland, and more broadly across the NEM, providing further updates should conditions change.

Also last week, AEMO informed the market of the availability of a report outlining 18 discrete incidents, over a period of just under 3 years, that included SCADA failure in some way. The report also discusses what has been done to rectify.
First article today, recording a new ‘lowest ever’ point for demand in Victoria (Sun 31st Dec 2023), and possible intervention from AEMO has it looks to drop further, leading to possible grid instability.
Last week the AEMO released a preliminary report into the trip of the South East – Tailem Bend 275 kV line that caused SA to be islanded from the rest of the NEM for over a week.
