DPV Contingency 1 (DPVC1) in the SA Region on 15/02/2024
AEMO has detected there is an elevated risk of the contingent disconnection of Distributed PV (DPV) which, together with the risk of loss of scheduled generation, exceeds secure thresholds in the South Australia region from 1230 hrs 15/02/2024 to 1400 hrs 15/02/2024.
Maximum DPV generation forecast by the Australian Solar Energy Forecasting System 2 (ASEFS2) is 1737 MW at 1330 hrs and the secure ASEFS2 DPV generation limit for the forecast operating conditions is 1796 MW.
AEMO is seeking a market response.
An insufficient market response may require AEMO to take action or intervene to maintain power system security in South Australia. This may result in action such as the recall of planned outages, direction of scheduled generation, curtailment of non-scheduled wind generation, and an instruction / direction to maintain DPV generation below a secure DPV generation threshold.
AEMO estimates the latest time at which it may need to intervene through an AEMO intervention event is 1130 hrs on 15/02/2024.

Possible intervention to manage power system security in SA region
The synchronous generating units currently expected to be synchronised in SA from 0815 hrs 15/02/2024 will be inadequate to maintain a secure operating state in SA .
AEMO estimates that, in the absence of sufficient market response by 1530 hrs 14/02/2024, AEMO may need to intervene by issuing a direction requiring one or more SA synchronous generating unit(s) to operate or remain synchronised to maintain power system security in SA.
