Renewable Integration Study (RIS)

The Renewable Integration Study (RIS) is the first stage of a multi-year plan to maintain system security in a future National Electricity Market (NEM) with a high share of renewable resources. AEMO’s findings and recommendations in this report reflect both its day-to-day experience operating the NEM power system, and the results of extensive RIS modelling and analysis.

This Stage 1 RIS report takes the ISP’s projections as given and investigates in detail the challenges in the short term, to 2025, of maintaining power system security while operating this resource mix at very high instantaneous penetrations[1] of wind and solar generation. It recommends actions and reforms needed to keep operating the NEM securely, now and as the power system transitions. AEMO looks forward to engaging with stakeholders to refine and progress the recommended actions, including assessing the potential roles of both existing and emerging technologies.

With this report, AEMO aims to provide foundational engineering perspectives for the ISP, Energy Security Board (ESB), industry, market institutions, and policy-makers. The RIS’s technical perspectives will ideally inform future investments, regulations, and market designs to securely operate the NEM power system with very high instantaneous penetrations of renewables.

[1] Instantaneous penetration of wind and solar is the half-hourly proportion of underlying demand that is met by wind and solar resources.

Webinars

  • RIS 101 webinar - May 2020

    The RIS 101 webinar is a non-technical description of the RIS. It is intended to provide a basic understanding of the areas studied in the RIS and why these areas are important for the Australia’s energy future. It is intended as an accessible introduction for stakeholders with little understanding of engineering concepts or energy regulatory frameworks.

  • RIS Technical overview webinar - May 2020

    The RIS technical overview webinar provides a summary of the technical areas studied in the RIS and their associated recommended actions. Some understanding of engineering concepts and energy regulatory frameworks is assumed. 

  • Appendix A – Distributed Solar PV

    This webinar is intended to provide a summary of the key findings and actions that come out of the distributed PV technical appendix. It also provides an overview of key concepts that are important in understanding distributed PV.

  • Appendix B – Frequency Control

    This webinar is intended to provide a summary of the key findings and actions that come out of the frequency control technical appendix. It also provides an overview of key concepts that are important in understanding frequency control and an explanation of key figures in the report. 

  • Appendix C – Variability and Uncertainty

    This webinar is intended to provide a summary of the key findings and actions that come out of the variability and uncertainty technical appendix. It also provides an overview of key concepts that are important in understanding variability and uncertainty and an explanation of key figures in the report.

Engagement

Following release of the RIS Stage 1 report in April 2020, AEMO consulted with a wide range of stakeholders, providing information on the methodology, results and recommendations of the study and discussed feedback, concerns, or suggestions regarding the RIS Stage 1 report and priority focus areas for the future.

Given current COVID-19 restrictions, AEMO used a variety of engagement options to maximise the value to all stakeholders, including a webinar series for technical and non-technical audiences (see above), open industry and consumer workshops, targeted video conference workshops for industry and international groups, fact sheets (see above) and the opportunity for written submissions. 

Written submissions on the RIS Stage 1 report and priority focus areas for the future closed at the end of June 2020. AEMO will review submissions and is exploring avenues for engagement on future stages of the RIS. 

More information will be posted to the website and our mailing list as it becomes available.
