This role is a part of the Ex-post team within Markets and Reliability. This is a union job.
What makes this role exciting
The energy sector is rapidly evolving, offering exciting new opportunities for those who want to make a difference.
The Ex-post team plays a critical role in ensuring integrity in Ontario's electricity market by collaborating with both Day-Ahead and Real-Time operators to resolve discrepancies and errors to maintain accurate market data for settlement purposes.

What you'll do
In this role, you'll make a meaningful impact by contributing to the IESO team and supporting the electricity needs of the province through:
- Using power system and market rule understanding, provide accurate, timely and auditable settlement-ready data from real-time processes to associated IESO departments consistent with the obligations of the Market Rules and supporting departmental processes. Collect, verify and prepare settlement-ready data for off-market transactions. These data submissions include but are not limited to areas such as Market Suspension and Resumption, Administrative Pricing, Market Data Verification, Ancillary Service Contracts, Emergency Transactions, Notice of Disagreements, Data Publishing, and associated reporting.
- Invoke the functions to establish administrative prices and corresponding market schedules:
- following outages to IESO administered markets software, hardware and communications systems that resulted in the IESO being unable to publish prices and market schedules;
- where incorrect inputs which affected the output of the dispatch algorithm have resulted in incorrect prices;
- where the real-time energy market or the operating reserve market has been suspended.
- Recommend the required course of action in establishing administrative prices and corresponding market schedules.
- Perform market data correction for both routine and complex issues. Correct energy and operating reserve market data before this information is provided to the settlement process for determining settlement amounts.
- Prepare reports such as Dispatch Deviation Report. Confirm that all reports have been successfully published.
- Support Market Participant NOD (Notice of Disagreement) investigations to determine actions required to ensure correct settlement outcome.
- Provide input to the ongoing improvement of Ex-post tools and recommend changes and development of software tools.

In a typical day, you will provide technical expertise and analysis in the provision of accurate, timely and auditable settlement-ready data (including prices and schedules) from real-time processes to associated IESO departments consistent with the obligations of the Market Rules.
