The IESO Settlement Schedule and Payment Calendars provide the timelines according to which market participants receive settlement statements and submit or receive payments for invoices. There are separate calendars for the physical market (day-to-day energy generation or consumption) and the financial market (transmission rights auctions) to reflect the different market activities of market participants.

Given the nature of its business, the IESO publishes many different technical and market documents, which include market rules, market manuals and technical interface documents. The timing of the regular release of new and updated documentation is outlined in the IESO’s Baseline Calendars. Also listed is the Reliability Compliance Calendar which describes the obligations of market participants to submit plans and forecasts which help to ensure continued system reliability.

The IESO is currently developing a calendar that will consolidate all upcoming events and incorporate much of the data on this page.
