• Whole of System Planning

    Currently, there is no single entity responsible for planning the power system that delivers electricity to households and businesses in the south west of the State. The Australian Energy Market Operator (AEMO) forecasts our generation needs, while Western Power is responsible for planning the development of its network.

    This system has served us well-enough in the past. However, managing our power system through the transition to renewable and distributed electricity sources requires stronger coordination to provide clear information for investors and planners, and to guide the development of the power system of the future.

    In response to these challenges, the Government is developing a Whole of System Plan, bringing together the important aspects of power system planning under a single umbrella.

    Image explaining the Whole of System Plan stages, with commencement in April 2019, consultation with stakeholders mid-2019 with the Whole of System Plan to be presented to Government by mid-2020 and ongoing plans from 2022 onwards.The Whole of System Plan for the south west will:

    • identify the best options for investment in our power system, to maintain security and reliability at the lowest sustainable cost;
    • assist in the transition to a lower-emissions power system by guiding the efficient integration of renewable generation and identifying opportunities for energy storage, which will play an increasing role in meeting our essential electricity needs; and
    • provide guidance to regulators and industry regarding efficient power system investment, and to policy–makers on the future needs of the power system.

    Next Steps

    Led by the Energy Transformation Taskforce, the initial Whole of System Plan will leverage recent modelling of the generation mix in the south west of the State undertaken by the Public Utilities Office. The plan will be developed in close collaboration with Western Power and AEMO, and in consultation with stakeholders.

    The initial Whole of System Plan will be delivered to Government by mid–2020.

    Consultation

    Stakeholders are invited to attend an Industry Forum on the Whole of System Plan. At the Industry Forum, the Energy Transformation Implementation Unit, supported by Western Power and the Australian Energy Market Operator, will outline and seek feedback on the proposed modelling scenarios, inputs and assumptions to be used in the development of the inaugural Whole of System Plan.
