On 5 May 2020, the Australian Energy Market Operator (AEMO) submitted a rule change request seeking to establish a framework to enable it to set initial minimum technical standards for DER.

The rule change request proposed to oblige AEMO to create a subordinate instrument under the National Electricity Rules that sets minimum technical standards for DER.

Draft rule determination

On 3 December 2020, the AEMC made a draft determination for a more preferable draft rule to create an initial set of technical standards that will apply to DER across the National Electricity Market (NEM). The draft rule is expected to address the immediate concerns arising from the increased uptake of small rooftop solar generators while avoiding the implementation of new, potentially inefficient costs on industry and customers.

Stakeholders are invited to provide feedback on the draft determination and rule by 14 January 2021.

Details of the draft rule

The more preferable draft rule amends the National Energy Rules (NER) to require all new or replacement micro-embedded generators – primarily rooftop solar systems – connecting to distribution networks to be compliant with the DER Technical Standard.

The key components of the draft rule are:

  • A requirement that all embedded generating units connecting by way of a micro EG connection service must comply with the DER Technical Standards. The DER Technical Standards includes the requirements set out in AS 4777.2:2015 and a new Schedule 5A.2 of the NER (which incorporates AEMO’s short duration under voltage response test requirements).
  • A requirement on DNSPs to include in their connection agreements made under Chapter 5A of the NER a requirement that all connections for micro embedded generation by way of a basic micro EG connection service must comply with the DER Technical Standards.
  • Supporting the application of existing compliance and monitoring systems under the Clean Energy Council (CEC) and the Clean Energy Regulator (CER), relating to the certification of products and installers of electricity generating systems.
  • A requirement for the rule to commence six months after it is made, to allow for the implementation of the new requirements.
