The latest news in the National Electricity Market (NEM) is AEMO’s goal to be capable of handling periods of 100% instantaneous renewables penetration by 2025. This is a significant challenge and fitting given the pace the NEM is moving to, supporting increasingly higher levels of instantaneous (and increasingly asynchronous) renewables on a regular basis.
While this challenge may not be as pressing for all NEM regions, the need to identify methods/technologies to enable higher asynchronous generation is a welcomed objective in future-proofing the NEM. To visualise the differences between regions in this transition, the chart summarises the last 18 months in the NEM into duration curves of the renewable percentage of local generation for each NEM region and the level of supply being supplied from asynchronous sources (this includes import volumes in the calculation). Behind-the-meter resources have been omitted from the analysis, given the grid operation focus.
