Australia Loses Three Years on DER Technical Standards Governance Reforms

Regulatory delays and a rejected rule change have set Australia's distributed energy resource technical standards governance at least three years behind where it should be, costing consumers revenue opportunities and hampering grid integration of solar, batteries, and electric vehicles. The Australian Energy Market Commission's September 2023 final report concluded that reform is needed but handed responsibility back to state and federal jurisdictions for further consultation.

The governance of DER technical standards was identified as a foundational challenge in 2019, when the Energy Security Board commissioned a review that was completed in March 2020. A rule change request supported by 32 stakeholder submissions was lodged in September 2020 by Dr Kerry Schott seeking new governance arrangements under the National Electricity Rules. In March 2022 — eighteen months later — the AEMC rejected the rule change, arguing existing powers were sufficient. Six months after that decision, the AEMC issued a new consultation paper on consumer energy resource technical standards, and in April 2023 commissioned Baker McKenzie to review the same ground already covered in 2020.

The AEMC's September 2023 final report acknowledged that reform is needed to develop an enduring NEM-wide regulatory framework for CER technical standards, then proposed four governance options — handing the decision back to jurisdictions for consultation. Report author Dr Gabrielle Kuiper, who served as DER Strategy Specialist with the Energy Security Board from 2019 to 2020, notes that the only DER technical standard currently embedded in the National Electricity Rules is the AS4777.2:2020 inverter standard. Without a functioning standards body, DER cannot participate in energy markets on an equal footing with large wind and solar farms.

The practical costs of the delays are significant. Approximately 100,000 electric vehicles were sold in Australia in the three years to 30 June 2023, each representing a missed opportunity for smart managed charging integration. EV charging requirements still vary across states and territories, with vehicle-to-grid standards unresolved across physical connectors, interfaces, power levels, battery standards, and energy exchange protocols. Standards governing hot water systems, air conditioners, and smart appliances remain absent from the NER, meaning households cannot earn revenue from demand response. Dr Kuiper argues it is time for energy market bodies to substantially upgrade their capacity and commitment to DER governance.

Key figure — Approximately 100,000 EVs were sold in Australia in three years to June 2023, each a missed smart-charging integration opportunity due to absent DER standards.
