Pre-production Refresh

AEMO Australian Energy Market Operator periodically refreshes the pre-production system with data from the production system. An outage of up to five days can occur to the pre-production environment during this period. Participant access is not restricted. However, AEMO does not guarantee the pre-production data content or system availability. During the refresh, access to other AEMO systems such as AWEFS Australian Wind Energy Forecasting System. Established in response to the growth in intermittent generation in the NEM, and the increasing impact this growth was having on NEM forecasting processes. The system aims to provide better forecasts that will drive improved efficiency of overall NEM dispatch and pricing, and permit better network stability and security management., EMMS Energy Market Management System (formerly MMS); software, hardware, network and related processes., OPDMS Operations and Planning Data Management System. A software system that supports the planning and operations functions in an electricity market environment., and STTM Short Term Trading Market. A wholesale market that facilitates short-term gas trading between gas shippers and users. STTM hubs operate in Adelaide, Brisbane and Sydney. may be intermittently affected.

During a refresh, AEMO expects participants to:

• Observe the backup production date when the data is applied to the pre-production environment.

• Based on AEMO’s project changes production backup date, review if you need to refresh your pre-production data from your production system to align with AEMO’s pre-production. How you do the refresh depends on the configuration of your systems.
