Overview

On 19 September 2017, the Australian Energy Market Commission (AEMC) published a consultation paper for the Generator technical performance standards rule change.

On 19 September 2017, the Australian Energy Market Commission (AEMC) published a consultation paper for the Generator technical performance standards rule change.

The consultation paper seeks stakeholder input on AEMO’s proposed changes to the NER framework for:

  •  access standards for generators and
  •  the framework for the negotiation of performance standards.

Stakeholders are invited to provide written submissions on the consultation paper by 31 October 2017.

Background

On 11 August 2017, the Australian Energy Market Operator (AEMO) submitted a rule change request to the AEMC seeking changes to the access standards for generating systems in the National Electricity Rules (NER) and 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.

Issues identified and rule change request

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.

The Commission will also be holding stakeholder workshops to facilitate input on the issues and potential solutions in this rule change. Further information on these workshops will be provided as assessment of the rule change progresses.
