The 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.
Under the South Australia Ministers declaration, the instrument’s prescribed period is each working weekday from January 8, 2024 – March 18, 2024 for the trading periods between 3pm and 9pm (EST).
As of January 14, 2021, large generation businesses in South Australia, namely Origin, AGL and Engie, will be required to offer contracts for the prescribed periods at specific times on the Australian Securities Exchange (ASX). This is a requirement under the Market Liquidity Obligation (MLO).
The Australian Energy Regulator (AER) has a monitoring and compliance role to ensure that Origin, AGL and Engie offer appropriate products on the ASX as required.
