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 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.
 Instantaneous penetration of wind and solar is the half-hourly proportion of underlying demand that is met by wind and solar resources.
Renewable Integration Study Stage 1
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.

International Insights for Australia
The next step of the engagement plan includes consultation with a broad range of stakeholders through a variety of formats, as outlined in the table below. Given current COVID-19 restrictions, AEMO is exploring a variety of engagement options to maximise the value to all stakeholders. Stakeholder feedback and suggestions on other approaches are welcome.
Open Industry video conference workshop
10:00 - 11:30 AEST, 11 June 2020
Open invite for feedback from stakeholders on the findings and recommendations of the study.
