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.

Reports

Engagement

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.

Engagement activity

Objectives

Timeline

Webinar(s)

  • Recordings will be published on the RIS website.

Inform stakeholders of the results and key insights.

May 2020

Videoconference workshops

  • Workshops will be broken-down into discrete topics and/or industry groups to keep attendee numbers at each workshop small enough to enable meaningful discussion and debate.

  • AEMO welcomes feedback and suggestions from stakeholders regarding the workshop topics and structure they’d like to see.

Consult with stakeholders – open dialogue and discussion regarding matters of most interest, including but not limited to:

  • Discussion and clarification about the methodology and results of the study.

  • Discussion regarding the actions arising from this report and priority focus areas for the future.

  • Exploring the relevance of findings and insights to ongoing reform processes.

May-June 2020

Written submissions

  • AEMO welcomes submissions from stakeholders wishing to provide formal written feedback, concerns, or suggestions regarding the RIS Stage 1 report or priority focus areas for the future.

Consult with stakeholders – allow opportunities for formal written responses from stakeholders regarding the RIS Stage 1 report or future activities.

 

June 2020
