The Retailer 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. 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 (ESOO) it must provide the Australian Energy Regulator (AER) with a reliability instrument request.
T-3 Reliability Instrument
On 22 October 2024, the AER made a T-3 Reliability Instrument for Victoria from 1 December 2027 to 31 March 2028 inclusive.
Notification of closed T-3 Reliability gap
On 26 August 2026, AEMO notified the AER that the Victoria 1 December 2027 – 31 March 2028 reliability gap is no longer forecast. As a result, the reliability gap is now closed.
