Regular**Business Unit**:
Markets & Reliability**Why join us?**
You’ve got great skills. And you want to use them in an organization where you know what you do every day matters. We get that.
We also know that ensuring Ontarians have access to affordable and reliable power doesn’t happen by accident. So we give you the tools, flexibility and support you need to achieve your goals, and development opportunities to help you grow. You’ll thrive in a collaborative, team-based environment that values your unique skills and experiences - and recognizes that when you do better, we become even better too.
**Who we are**
The Independent Electricity System Operator (IESO) works at the centre of the province’s power system, ensuring Ontarians have access to reliable and cost-effective electricity when and where they need it. We operate the province’s electricity grid 24/7, design, run and oversee the wholesale electricity markets, and plan and prepare to meet Ontario’s electricity needs - now and into the future.
**The opportunity**
- As a member of the Control Room Operations Team, the System Operator helps fulfill the IESO’s roles as Reliability Coordinator, Transmission Operator and Balancing Authority for the province of Ontario by administering the IESO Controlled Grid (“ICG”) and the IESO Administered Markets (“IAM”) on a minute-to-minute basis ensuring a reliable, competitively-priced and sustainable electricity supply for the province:
- through intense and timely analysis, investigation and execution of control actions;
- in compliance with NERC reliability standards and NPCC criteria;
- within the Market Rules and relevant Regulations;
- through collaborative work with other Operations Team members;
- and under the general direction of the Shift Superintendent.
**What you'll do**
- The System Operator works collaboratively with other Operations Team members to execute the minute-to-minute administration of the IESO Controlled Grid (“ICG”) and the IESO Administered Market (“IAM”) to ensure a reliable, competitively priced and sustainable electricity supply for the province and help fulfill the IESO’s roles of Reliability Coordinator, Transmission Operator and Balancing Authority for the province of Ontario.
- The System Operator:
- monitors/identifies potential compliance issues and surveillance activities within the IESO;
- maintains the daily log ensuring all relevant information is documented and correct;
- performs other duties comparable in scope and complexity to the Key Responsibilities listed here as required; and
- executes specific duties and responsibilities related to the following functions:
- IESO Administered Markets;
- IESO Controlled Grid;
- System for Markets;
- Contingency Operation and System Restoration;
- Outage Plan;
- Tool Set;

- Immediately direct generation or shed load to mitigate critical conditions and preserve the integrity and reliability of the Bulk Electrical System (BES).
- Coordinate the IAM as per market rules, NPCC criteria and NERC standards.
- Manage the inputs to the Dispatch Scheduling and Optimization engine (“DSO”), review the solution (both real-time (multi-interval optimization (“MIO”)) and pre-dispatch) to ensure accuracy, prepare to manually intervene in the solution if required, and provide final approval of the IAM 5-minute dispatch to maintain the balance of load and generation.
- Monitor/identify/investigate/resolve problems in the real-time and pre-dispatch schedules.
- Monitor/assess/recommend/implement/reconcile ancillary services contracts (e.g. voltage support, regulation) to meet market rule requirements and recommend further actions if the contract requirements are not being met.
- Implement interchange transactions between the IESO and its interconnected neighbours. This includes verifying the accuracy of NERC E-Tags, curtailing tags as required and providing final approval or denial of E-tags and transactions.
- Liaise with neighboring Reliability Coordinators (“RC”) and Balancing Authorities (“BA”) to ensure all interchange schedules are correct and agreed to. This includes working to resolve disagreements in schedules and arriving at an agreed to solution.
- Monitor/assess/implement the required control actions to maintain inadvertent interchange as low as possible as per procedures.
- Provide final approval for all planned generation outages, and implement connection and disconnection of generators from the ICG into the market tools.
- Implement demand response programs (e.g. OPA DR3 program) as per procedures and direct participants accordingly.
- Implement time error corrections and control actions as directed.
- Reconcile daily reports such as inadvertent, market reports, etc.
