AEMO Pre-Production Environment

AEMO has pre-production and production environments that are maintained separately. New features are added to the pre-production environment and announced in change notices and technical specifications, before being released into a ‘live’ production environment.

The pre-production environment is intended for participant testing and training purposes. Three types of participant testing were identified:

  • 1. Industry testing

    Self-testing of functionality such as connectivity, and/or coordinated multiparty testing of functional scenarios.

  • 2. Invitation to industry testing

    Coordinated testing of business process scenarios with a select number or subset of participants with systems ready for testing.

  • 3. Market trials

    Coordinated multi-party end-to-end testing of business process scenarios.

Industry testing

  • 5MS Retail
  • 5MS Settlements release
  • 5MS Bidding service release

5MS Retail capabilities were released into the pre-production environment at approx. 5pm on 14 April, ahead of the planned 19 April schedule. This release marks the formal start of the Retail industry test phase.

This phase allows participants to test their internal systems with AEMO’s new Retail solution.

The key changes released into pre-production, reflect the functionality that will go-live on 31 May 2021 (30-min settlement with 5-min reads supported).

For further details, refer to the MSATS technical specification for 46.98 document or refer to the Retail pre-production FAQ guide link at the bottom of this page.

The 5MS Program will release 5MS Settlement platform changes into AEMO’s pre-production environment on Monday 22 March 2021. This allows participants to use the pre-production environment to carry out their own tests (including B2B testing).

For further details about this release, refer to the Settlements FAQ guide link at the bottom of this page.

The 5MS Program released 5MS Dispatch and Bidding changes into AEMO’s pre-production environment on Monday 30 November 2020. This allows participants to use the pre-production environment to carry out their own tests (including B2B testing). 

Access to pre-production is available via the following URLs/protocols, using the same log-in details set up by the participant’s MSATS Administrator as at 1 October 2019. The naming conventions are consistent with Production environments.
