On 12 August 2021 the AEMC published its Access, pricing and incentive arrangements for distributed energy resources final determination. The determination changes the energy rules with the aim to integrate more distributed energy resources (DER) such as small-scale solar, batteries and electric vehicles into the grid. The rule change requires distribution businesses to plan for the provision of export services and strengthens customer protections and regulatory oversight by the AER.
The AER is responsible for developing and consulting on the customer export curtailment value (CECV) methodology to be used to calculate CECVs each year. CECVs will capture the detriment to customers and the market when DER exports are curtailed and help guide efficient levels of investment for export services. The AER is required to publish the initial CECV methodology and values calculated in accordance with the CECV methodology by 1 July 2022. The CECV methodology compliments our guidance note for assessing DER integration expenditure.
On 30 June 2022 the AER released the final CECV methodology, explanatory statement along with the CECV workbook.
On 30 June 2023 the AER published an updated CECV workbook and summary note.
