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 29 August 2024, AEMO provided the AER with a reliability instrument request for Victoria from 1 December 2027 to 31 March 2028.
The size of the forecast reliability gap is 130 megawatts (MW). This reliability instrument request applies to the forecast reliability gap period of 1 December 2027 to 31 March 2028 inclusive. The region in which the forecast reliability gap is forecast to occur is Victoria. AEMO’s one-in-two-year peak demand forecast for the forecast reliability gap period is 10,303 MW (reported on a 50% probability of exceedance [POE], ‘as generated’ basis). The trading intervals during the forecast reliability gap period are those that fall between 3:00 pm and 9:00 pm on working weekdays in December 2027, January 2028, February 2028, and March 2028. For clarity, this means the trading intervals occurring between the periods ending 3:05 pm and 9:00 pm inclusive.
Invitation for submissions
Interested stakeholders are invited make a submission on the Reliability Instrument request by 16 September 2024.
Written submissions or requests to make a submission via alternative methods should be emailed to rro
aer [dot] gov [dot] au (rro[at]aer[dot]gov[dot]au).
Indicative timelines for this instrument are available under the Initiation milestone.
