The IESO publishes a number of calendars, which highlight key settlement and payment dates, crucial submission deadlines and release schedules for critical technical documentation.
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.
Reliability Outlook Information Submission Calendar
Market participants are required under the market rules to provide information to the IESO to enable the IESO to conduct reliability assessments. The submission deadlines for input information for the Reliability Outlook (formerly known as the 18-Month Outlook) and other reliability assessments are listed.
