Annual Adjustment
29 June 2026
On the 29 June 2026, we published new customer export curtailment values (CECVs) for the 2026-27 financial year. This represents the final update under the current 2022 CECV methodology. We are required to review the CECV methodology at least every five years and determine whether any changes are required. We intend to commence a review of the CECV later this 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 2025-26 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 by removing values for 2025-26 and adding values for 2045-46.
The accompanying explanatory note explains our decision to update CECVs and emissions intensity profiles for 2026-27. In line with the CECV methodology, we have considered the Australian Energy Market Operator’s updated inputs and assumptions for the Integrated System Plan. We considered the changes in input assumptions were not likely to materially impact CECVs if they were re-estimated. As such, only an inflation adjustment is needed to maintain the real value of estimated CECVs.
A DNSP model is available on request. It helps networks practically implement CECVs for export service investment projects and includes the new CECVs.
