Transitional Services

AEMO can now procure non-market ancillary services (NMAS) that fall outside the scope of the existing services available under the NER for power system security. These services are referred to in the ISF Rule as ‘transitional services’, and the new provisions in the NER dealing with the procurement and enablement of these services are referred to as the ‘transitional services framework'.

The Transitional Services Guideline recognises a need for flexibility due to the uncertainty inherent in the scope of the transitional services that may need to be acquired. The transitional services framework is established in recognition that not all security needs may be met by existing security frameworks throughout the energy transition.
