Stakeholder Engagement at the IESO

Public Information Sessions

To complement its stakeholdering efforts, the IESO regularly holds public information sessions on various aspects of the system and market.


Market Renewal Education Workshops

The IESO is hosting five education workshops to help stakeholders, market participants and the broader sector better understand the design elements of the market renewal project.

The half-day workshops are intended to be informative and educational on how market design components work with a focus on how they are used in other jurisdictions. The content is targeted to build capacity in these areas. They are also intended to be interactive with opportunities for questions and discussion. The first workshop provides a general overview, and the subsequent four will provide more detail and context into the elements.

The workshop schedule is:

Market Design Overview, January 25, 9am-12pm
Single Schedule workshop, February 8, 9am-12pm
Capacity Market, February 15, 9am-12pm
Day-Ahead Market, February 22, 9am-12pm
Real-Time Unit Commitment, February 22, 1pm-4pm

To register for one or all of these workshops, please register at engagement@ieso.ca.


Webinar – Interchange Enhancements (e-Tag submissions) – January 24, 2017

A follow-up webinar on the Interchange Enhancements project will be hosted on Tuesday, January 24. The Interchange Enhancements project is aimed to improve the operation and management of interchange scheduling related tasks by enhancing existing interchange scheduling systems and processes.

Feedback will be posted on this page in the Interchange Enhancements section prior to the January 24 webinar. The IESO thanks all of those who participated in the first meeting.

For anyone interested in this project, please register with the IESO at engagement@ieso.ca to receive the webinar details, presentation in advance of the webinar and email updates on the project.

Webinar – Interchange Enhancements – November 29, 2016

The IESO is planning to make changes with respect to the submission of e-Tags and the management of those transactions specifically within the mandatory window. All interested stakeholders are invited to a webinar on Tuesday, November 29 from 1:00pm-2:30pm to discuss these changes.

The Interchange Enhancements project is aimed to improve the operation and management of interchange scheduling related tasks by enhancing existing interchange scheduling systems and processes.  To support this objective, the project aims to limit manual intervention and error margins and reduce time spent on the phone for both market participants and the IESO’s control room operators.  One of the main benefits the IESO is pursuing will be to enable market participants to manage e-Tag ID changes electronically, without the need for IESO operations approval within the existing mandatory window.

For more information on the project and its potential impact on the manner in which your organization manages e-Tags, please register with IESO Engagement to receive the webinar log-in details. Stakeholders will have an opportunity to ask questions, seek clarification and provide comments on the material presented.

Webinar – Grid-LDC Interoperability Framework – November 25, 2016

The IESO is hosting an information webinar on Friday, November 25 at 1:00 pm to discuss the development of a grid-LDC interoperability framework. The objective of the framework will be to identify opportunities to enhance the reliability and efficiency of Ontario’s electricity grid through the coordination of IESO and LDC-controlled resources. It is anticipated that operations representatives of LDCs will have the greatest interest in this webinar; however, all interested parties are welcome to participate. To register, email engagement@ieso.ca.

Through a Grid-LDC Coordination partnership with PowerStream, the IESO has identified existing real-time IESO market and system information that may be useful to LDCs in managing their day-to-day operations as well as a number of short and long-term collaboration opportunities for the IESO and LDC’s. The IESO will present these early learnings during the webinar and provide an opportunity for input on the draft framework including identifying any barriers or other opportunities that might not have been contemplated thus far.

Webinar – Proposed changes to Peak Demand Hours and the Adequacy Report – November 25, 2016

The IESO is planning to make changes to Peak Demand Hours and the Adequacy Report. All interested stakeholders are invited to a webinar on November 25 from 10am-12pm. 

The IESO is proposing to determine which hours to use a peak demand forecast in the pre-dispatch scheduling timeframe on a dynamic basis. This would be reflected in the Adequacy Report. New information regarding IESO’s regulation requirement, and wind and solar forecast publishing logic to be added in the Adequacy Report will also be presented.

If interested in participating in the webinar, please register with IESO Engagement to receive the webinar details. Stakeholders will have an opportunity to ask questions, seek clarification and provide comments on the material.

Webinar – Proposed change to curtail wheel-through transactions as a control action – April 28, 2016

The IESO is proposing changes to Market Manual 7.2: Near-Term Assessments and Reports. The proposed change would add a new condition in section 1.3.4: IESO Control Actions (Nuclear Manoeuvres Forecasted or Occurring) to allow the IESO to curtail wheel-through transactions if a nuclear shutdown is scheduled in future hours concurrent with wheel-through transactions.

Curtailing wheel-through transactions to prevent a nuclear shutdown may be the appropriate market response during this circumstance given:
  • The IESO’s scheduling tool does not account for all of the implications of a nuclear shutdown for future hours – including the fact that a nuclear unit can take up to 72 hours to re-start after a shutdown; and
  • The fact that the next set of economic resources after the nuclear shutdown are likely to have limited flexibility to be dispatched in this timeframe.

The IESO hosted a stakeholder webinar on April 28 at 10:00 am to discuss the proposal in more detail, answer questions and outline next steps.
