Executive Summary

This update to the National Electricity (South Australia) Act 1996 introduces a significant new power for the South Australian Minister to create initial rules for credit support arrangements during Retailer of Last Resort (RoLR) events. Enacted through the National Energy Retail Law (Retailer of Last Resort) Amendment Act 2025, this change, effective 18 December 2025, establishes a fast-track mechanism under the new Section 90EH of the National Electricity Law. This allows for rapid regulatory responses to mitigate financial risks associated with retailer failures, bypassing the standard rule-making process. The change is supported by consequential amendments to definitions within the Act to ensure legal consistency. This signals a heightened focus on market stability and the financial resilience of energy retailers.

Impacted parties

This update primarily impacts electricity retailers, the Australian Energy Market Operator (AEMO), the Australian Energy Regulator (AER), and Distribution Network Service Providers (DNSPs) by introducing a new ministerial power to establish rules for credit support during Retailer of Last Resort events.
