  • Purpose

    AEMO’s Systems Workstream is responsible for the design, development, testing and implementation of systems to support the changes to rules and procedures as a result of the Five-Minute Settlement (5MS) and Global Settlement (GS) initiatives. The workstream will produce the required technical documentation to facilitate participant changes to systems.

    Packages and Stakeholder Consultation

    AEMO will consult on proposed systems amendments via the Systems Working Group and any required Focus Groups. AEMO will cover each specific area, identified within the functional areas, in the High-Level Impact Assessment (HLIA).
