This rule change request from AEMO proposes a number of changes to the technical performance standards for generators seeking to connect to the national electricity market, and the process for negotiating those standards.
On 19 September 2017 the Australian Energy Market Commission (AEMC) published a consultation paper for this rule change request.
The consultation paper sought stakeholder input on the Australian Energy Market Operator’s (AEMO’s) proposed changes to the National Electricity Rules (NER) on:
- access standards for generators and
- the framework for the negotiation of performance standards.
On 24 October 2017 the AEMC published supplementary advice received from AEMO, providing clarification on a number of the changes included in the rule change request.
Submissions closed on the consultation paper on 7 November 2017 and are available below.
On 28 November 2017 the AEMC extended the period of time for making a draft determination. On 14 March 2018 the AEMC further extended the period of time for making a draft determination until 5 June 2018, with a final determination now due on 2 October 2018.
The timeframes were extended due to the complexity of the issues raised by the rule change and further issues identified by stakeholders during consultation.
On 11 August 2017 AEMO submitted a rule change request to the AEMC seeking changes to the access standards for generating systems in the National Electricity Rules (NER). AEMO also requested changes to the negotiating framework that translates those access standards into the standard of performance required of the physical equipment that makes up and connects to the power system.
Due to the changing generation mix in the power system, AEMO considers that the current access standard settings in the NER and the negotiating framework to set performance standards are not adequate to ensure the ongoing security of an evolving power system.
To address these issues, AEMO proposes:
- amending or introducing a number of access standards for connecting generators, including those relating to voltage control and reactive power provision, disturbance ride through, system strength, active power control and remote monitoring and control
- amending the process for negotiating performance standards
- implementing transitional arrangements applying the changes to any performance standards agreed on or after 11 August 2017.
Assessment of this rule change request forms part of the AEMC’s broader package of system security work, which includes a range of measures to address a transforming power system with reduced inertia and system strength.
This rule change request also covers part of recommendation 2.1 made by the Finkel Panel in its review into the future security of the national electricity market to “review and update the connection standards in the NER in their entirety”. This rule change request relates to the connection standards for generators, and not for other equipment such as market network service providers and certain large customers.
