New South Wales: December 2025 - February 2026

Commencement date: 
31 August 2022
Regulatory period: 
1 December 2025 to 28 February 2026


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.

Forecast Reliability Gap

In the 2022 ESOO AEMO has forecast a 790 MW reliability gap in New South Wales in 2025-26.

On 31 August 2022 AEMO requested the AER to make a T-3 reliability instrument. The T-3 Reliability instrument applies to the New South Wales region of the NEM for the trading intervals between 2 pm and 9 pm Eastern Standard Time, each weekday during the period 1 December 2025 to 28 February 2026 inclusive. The size of the forecast reliability gap is 790 MW. AEMO's one-in-two year peak demand forecast for the forecast reliability gap period is 13,133 MW (reported on a 50% Probability of Exceedance, ‘as generated’ basis). We now must make a decision on whether to issue a reliability instrument by 31 October 2022.

When deciding on the request we must consider the decision making criteria as set out in the National Electricity Rules (NER). How we will consider these is set out in the Interim reliability instrument guidelines.

Submissions on the reliability instrument request closed on 14 September 2022. No submissions were received..
