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 31 October 2023 the AER made a T-3 Reliability Instrument for New South Wales from 1 December 2026 to 31 March 2027 inclusive.
On 21 August 2025, AEMO notified the AER that the New South Wales 1 December 2026 - 31 March 2027 reliability gap is no longer forecast. As a result, the reliability gap is now closed.
