Rule Change: Completed
On 8 December 2016 the Australian Energy Market Commission (AEMC) made a final rule determination and more preferable final rule, which would require distribution network service providers (DNSPs) to publish information about expected system limitations. The Commission does not implement ‘local generation network credits’ into the National Electricity Rules (NER).
The final rule would require DNSPs to annually complete a ‘system limitation report’ providing the following information:
- The name or identifier and location of network assets where a system limitation or projected system limitation has been identified during the forward planning period;
- The estimated timing of the system limitation or projected system limitation;
- The proposed solution to remedy the system limitation;
- The estimated capital or operating costs of the proposed solution; and
- The amount by which peak demand at the location of the system limitation or projected system limitation would need to be reduced in order to defer the proposed solution, and the dollar value to the DNSP of each year of deferral.
The system limitation report will offer consistent and accessible information that will enable embedded generators and other providers of non-network solutions to better use existing mechanisms in the NER.
Requiring DNSPs to include the dollar value of each year of deferral of a proposed solution will:
- provide the basis for measuring the financial viability of the project at the earliest opportunity;
- remedy some of the information asymmetry between non-network solution proponents and DNSPs; and
- provide some balance to the relative negotiating power between DNSPs and providers of non-network solutions, when they negotiate payments for providing network support.
On 15 July 2015 the AEMC received a rule change request to amend the NERs from the City of Sydney, Total Environment Centre, and the Property Council of Australia.
The rule change request was for distribution network service providers to calculate the long-term economic benefits that embedded generators provide to distribution and transmission networks, and pay embedded generators a local generation network credit that reflected those estimated long-term benefits.
The AEMC has held a webcast, stakeholder workshops and discussion groups to help inform our assessment of the proposal. Presentations and summaries can be found below.
