The Australian Energy Regulator (AER) has today published new customer export curtailment values (CECVs) for the 2025-26 financial year.
CECVs represent the detriment to all customers from the curtailment of exports from distributed energy resources (DER) and consumer energy resources (CER) due to network limitation. They can be used by a distribution network service provider (DNSP) to quantify the value of the export curtailment that is expected to be alleviated by a proposed project.
The new values are based on the 2024-25 CECVs, with an adjustment to account for inflation using the latest available consumer price index (CPI) data. We have also published the updated emissions intensity profiles, where the only change made was the removal of values for 2024-25.
The accompanying explanatory note outlines our approach to the updated CECVs and emissions intensity profiles for 2025-26. In accordance with the CECV methodology we considered the Australian Energy Market Operator’s updated inputs and assumptions for the Integrated System Plan. We did not consider that the changes were substantial or would have a material impact on the CECVs to warrant re-calculation.
Additionally, we have updated the DNSP model, which helps networks practically implement CECVs for export service investment projects, to include the new CECVs. This model is a large file and is not published on our website. Stakeholders can request the DNSP model by emailing AERInquiry
