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 24 October 2022 the AER made a T-3 Reliability Instrument for New South Wales from 1 December 2025 to 28 February 2026 inclusive.
Notification of closed T-3 Reliability gap
On 29 August 2024, AEMO notified the AER that the New South Wales 1 December 2025 – 28 February 2026 reliability gap in no longer forecast. As a result the reliability gap is now closed.
