The Retail Reliability Obligation (RRO) is designed to support reliability in the National Electricity Market (NEM). In particular it encourages retailers, and some large energy users, to establish contracts for their share of demand for a prescribed period.
The RRO can be triggered if the Australian Energy Market Operator (AEMO) identifies a reliability gap in a region of the NEM as part of its Electricity Statement of Opportunities. Each Minister for Energy in a NEM region also has the ability to trigger the RRO by making an instrument directly.
On 2 January 2025, the South Australia Minister for Energy and Mining triggered the RRO in South Australia for the first quarter of 2028.
Notification of closed T-3 Reliability gap
On 26 August 2026, AEMO notified the AER that the South Australia 10 January 2028 – 17 March 2028 reliability gap is no longer forecast. As a result, the reliability gap is now closed.
