On 26 June 2025, the Australian Energy Market Commission (AEMC), published a consultation paper examining the Integrated distribution system planning (IDSP) rule change request from Energy Consumers Australia (ECA).
Under the proposed rule change, the existing DAPR would be replaced with a biennial IDSP alternating with the AEMO Integrated System Plan, requiring DNSPs to undertake a more comprehensive planning review over a longer planning horizon.
Key elements of the proposal include requirements on DNSPs to:
- increase transparency of hosting capacity with new network utilisation metrics,
- consult with a broader range of stakeholders, and
- publish more data along with a Data and Insights Roadmap to outline how they would improve compliance and capabilities of publishing granular data.
The rule change request aims to address potential issues with the existing distribution annual planning process in the context of increasing Consumer Energy Resources and Distributed Energy Resources penetration.
The AER made a submission to the consultation paper on 29 July 2025.
