The Whole of System Plan (WOSP), launched in October 2020, is a detailed study of how our major power system may evolve over 20 years.
Using data provided by industry, the plan models four scenarios of how changes in demand, technology, and the economy may shape the way we use electricity and guide the investments we make over the coming decades to achieve lowest-cost, lower-emissions electricity.
To support the WOSP Report, an information sheet provides an overview of the methodology and input assumptions used to model the four WOSP scenarios: Cast Away, Groundhog Day, Techtopia and Double Bubble.
Appendix A contains the modelling methodology and assumptions and Appendix B provides the Assumptions Workbook in Excel format. Appendix C details modelling outputs and commentary and Appendix C - Modelling outputs provides a modelling workbook in excel format.

The Whole of System Plan modelling inputs were developed and tested via more than 70 meetings with energy sector stakeholders. This included one-on-one meetings with industry participants, investors and advocacy groups.
Stakeholders provided feedback on the modelling scenarios and the various inputs and assumptions. In many cases, stakeholders shared critical data such as operating costs, expected returns and plant characteristics. This information helped to improve the quality of the WOSP modelling inputs and therefore the robustness of modelling outputs.
As some of this information is confidential, it has not been included in the Information Paper or Assumptions Workbook below.
