AER - Assessing the performance of the wholesale cost model - 5 November 2025

On 5 November 2025 we also published Assessing the performance of the wholesale cost model, a supplementary report to the DMO 8 issues paper. This report was developed in response to stakeholder submissions received during our DMO 7 process that called for the performance of the wholesale cost model to be transparently reviewed against actual outcomes that have occurred in the market.

This report is relevant to the percentile estimate discussion in the DMO 8 issues paper. However, it is an independent report which stakeholders do not have to read in order to engage with the issues paper consultation process.
