2024 Transition Plan for System Security (TPSS)

The Transition Plan for System Security (TPSS) is an annual report focusing on maintaining power system security as the National Electricity Market (NEM) transitions towards lower emissions. It provides a structured approach for the energy sector to navigate key upcoming Transition Points – events that require material changes in the operational approach to managing power system security – over at least the next 10 years.

The inaugural Transition Plan for System Security (TPSS) communicated AEMO’s approach to managing power system security over short-, medium- and longer-term horizons, noting that immediate actions are required for all horizons to support adequate preparation for the long-term energy transition.
