Approved policy

The Emergency Management Policy (EMP), sets out the steps that we will take, as a reasonable and prudent operator, during an extended emergency. This includes the requirement for us to initiate an official conservation campaign under pre-determined conditions and, if needed, manage and co-ordinate planned outages as an emergency measure in anticipation of, or during, prolonged energy shortages.

Gas disruption scenarios

Outage management in dry winters

To assist in managing security of supply the system operator identifies asset owner outages that negatively impact security of supply when hydro storage crosses the 1% Electricity Percentage Risk Curve. These are the outages the system operator may request asset owners to reschedule when hydro storage crosses the 4% Electricity Percentage Risk Curve.  Identifying (and subsequentially rescheduling) these outages is intended to assist in conserving hydro resources. The system operator is seeking to avoid (to the extent reasonably possible) the need for an Official Conservations Campaign and act as a reasonable and prudent system operator when managing security during Security of Supply situations.

Asset owner outages that may negatively impact security of supply are shown in the link below
