Engagement at the IESO

​Stakeholder and community engagement is integral to the IESO's decision-making process. The goal is to provide individuals and organizations with the opportunity to provide input and feedback about proposed decisions or changes that affect them. The IESO supports transparency, efficiency and consistency in its stakeholder engagement efforts.​

The Engagement Principles guide the conduct of the IESO and stakeholders throughout
the engagement process.

Here are areas in which you can get involved.

See Upcoming Engagement Events.

Stakeholder Advisory Committee

The Stakeholder Advisory Committee (SAC) provides appointed stakeholder representatives with the opportunity to present advice and recommendations on market development, conservation and planning decisions directly to the IESO's Board of Directors and Executive Leadership Team. Members of SAC represent consumers, generators, distributors/transmitters, related businesses/services and Ontario communities.

Stakeholders are encouraged to contact their SAC representative to provide input on issues that affect them.

SAC meetings are open to all stakeholders with an interest in the electricity industry. Meetings are typically held in the Toronto area and may also be attended via conferencing service.

The Stakeholder Advisory Committee meetings are open to all stakeholders with an interest in the electricity industry. See webpage for more information and upcoming meetings. The SAC is scheduled to meet six times a year, with additional meetings as required.

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 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 - Recorded Presentation 
Single Schedule workshop, February 8, 9am-12pm - Recorded Presentation 
Capacity Market, February 15, 9am-12pm - Recorded Presentation

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.

IESO Engagement Initiatives

The IESO is committed to an open, two-way dialogue with stakeholders to help understand their views about proposed changes that may affect them. Below you will find active stakeholder engagement initiatives. Please see the IESO Engagement Update for a snapshot of stakeholder initiatives currently underway.

The Stakeholder Engagement Process outlines the process to solicit feedback from stakeholders.

  • new  Review of the IMDC Process

    The IESO is looking for stakeholder feedback to help shape an internal review of the Interim Market Document Change (IMDC) Process. The IMDC process is part of the baseline process. It is used to introduce a change to a market facing document (e.g. market manuals) between two baseline publication dates.

  • Capacity Exports

    The IESO is investigating the potential to allow Ontario generators to export their capacity to other jurisdictions. All stakeholders, or their representatives are invited to provide input into the process to establish the rules and protocols that would enable opportunities for market participants with generating capacity not required for Ontario’s reliability requirements to earn revenue by exporting this capacity. This initiative will be of specific interest to stakeholders who are interested in being able to offer their capacity in external capacity markets.

Community Engagement – Regional Planning

Integrated Regional Resource Plans (IRRPs) look at ways to ensure a reliable supply of electricity across Ontario. The IRRP compares relevant resource options such as conservation and demand management, distributed generation, large-scale generation, transmission and distribution.

For IRRPs currently under development, Local Advisory Committees are generally established at the start of the IRRP process and will remain in place throughout the 18-month planning timeframe.

Active Local Advisory Committees 

For a list of upcoming Local Advisory Committee Meetings, please see the Calendar of Events below.
