EUAA Submission: Redefining Roles & Responsibilities For Power System & Market Operations In A High CER Future
Emily Wood | August 20, 2025
Since rooftop solar (and now batteries) have been installed behind the meter, distribution businesses have evolved their operations to include distribution system operations (DSO). With Consumer Energy Resources now able to be bid into the NEM, DCCEEW are reviewing the role of distribution businesses and whether a seperate or independent DSO would be more efficient and therefore lower cost for consumers.
‘…The EUAA supports proposed rule changes where evidence points to an issue and the proposed rule change clearly leads to improved efficiency of markets and/or improved system security and reliability and where the costs and risks are appropriately allocated to those best able to manage them and do not significantly impact consumer bills.
We note that while many jurisdictions globally are investigating the future roles and responsibilities of distribution network service providers (DNSPs), the other jurisdictions’ electricity systems differ significantly from the NEM and how it operates. Differences between those jurisdictions and the NEM include ownership, scale, whether they are regional or metro based and where they are in the transition including the volume of CER and distributed energy resources (DER)[1] in their networks among many other differences. All of the differences mean that while we can look to them to see what structures work in their jurisdictions under their rules and circumstances, the differences are substantial enough between those DNSPs and the ones in the NEM that we need to develop a local approach should a real problem be identified….’
