Market Notice 121008: Three of four Uranquinty units trip during LOR1 condition

At 16:55 on 26th November 2024 AEMO issued an emergency events/conditions market notice regarding three unit trips at Uranquinty Power Station (Gas):

Notice ID               :     121008
Notice Type Description :     Emergency events/conditions
Creation Date           :     26/11/2024     16:55:00

AEMO ELECTRICITY MARKET NOTICE.

Non-credible contingency event - NSW region - 26/11/2024

At 1637 hrs Uranquinty Unit 12 tripped and at 1639 hrs Uranquinty Units 11 and 13 tripped.

AEMO has not been advised of any disconnection of bulk electrical load.

The cause of this non credible contingency event is not known at this stage.

This was followed up immediately by Notice Id 121009 at 16:56 noting an Actual Lack Of Reserve Level 1 (LOR1) in the NSW region.

The Actual LOR1 condition was forecast to continue until 1930.

This was immediately apparent in the actuals and subsequent P30 forecasts for NSW Available Generation which decreased dramatically, seen here in a screen grab from ez2view’s Forecast Convergence widget.

Nothing further at this point, but we’ll continue to monitor what unfolds.
