Market Information Working Group

Working Groups

The Market Information Working Group has been formed to look at enhancements or changes to market information. The IESO publishes market information to provide transparency, enable effective participation, and facilitate understanding and analysis of the IESO markets. The goal of this plan is to obtain advice from a broad range of stakeholders on enhancements to market information.

The creation of a Market Information Working Group will allow stakeholders to provide guidance to the IESO on how priorities are assigned to requests for new or enhanced reports and information.

The focus group will meet either in person or by teleconference, at least twice per year to evaluate proposals for changes to existing reports and requests for new types of public information, and to provide advice on prioritization of any updates.

The key deliverable is a list of the current status and classification of all information requests, which the focus group will review and provide input on.

Documents referenced on this page, but not posted, can be obtained by contacting with a link to the web page that lists the document and advise whether it needs to be provided in an accessible format. Please allow a minimum of one business day for a response.
