The current under-frequency standards are achieved through a combination of mandated generator and HVDC owner asset owner performance obligations (AOPO's), procurement of instantaneous reserves (IR) and mandated automatic under-frequency load shedding (AUFLS) obligations. Each component will be reviewed via a series of sub-projects. These projects are:

  • Extended load control project;
  • Technical review of IR products;
  • Technical review AUFLS arrangements;
  • Review of the asset owner performance obligations (AOPO's) and the system Operator's principal performance obligations (PPO's);
  • IR cost allocation
  • AUFLS exemptions; and
  • Consideration of market based AUFLS arrangements.
