To follow the earlier article this morning about AEMO’s ‘Threat to System Security’ Notice in the gas market to do with low storage level at Iona, the AEMO has followed up today by directing two gas-fired generators in Victoria offline … with some information published at 14:20:
‘AEMO has intervened in the DWGM and directed the curtailment of two gas fired generation facilities in line with previous communications issued for the Iona storage depletion threat to system security event. The direction will remain in effect until:
(a) It can be demonstrated to AEMO that the participant(s) have sourced gas supply to meet generation demand; or,
(b) AEMO determines that the threat to system security has ended; or
(c) AEMO determines that the direction is no longer required to maintain or improve reliability, system security or in the interests of public safety.
AEMO is seeking a market response to a threat to system security for gas days 11/07/2022 to 30/09/2022 due to Iona storage inventory depletion risk to the DTS Total System.’
As I publish this at ~17:35 there are gas-fired units running at Valley Power, Newport, Laverton North and Mortlake in Victoria.
… ‘interesting’ times ahead…
