About The Position

The IESO is committed to ensuring Ontario’s electricity system meets the province’s needs today and into the future. We are charged with purpose, delivering reliable, affordable, and sustainable electricity for homes, businesses, and communities across the province. We are energized to grow, embracing opportunities to shape the future of a dynamic and evolving energy sector while advancing our careers. We are powered by teamwork, supported by diverse and passionate colleagues who foster respect, celebrate successes, and thrive on shared achievements. At the IESO, it’s not just what we do—it’s who we are! Our central role includes managing the provincial power grid in real-time, overseeing and evolving Ontario’s electricity market, engaging with government, municipalities and Indigenous communities, and planning for Ontario’s future electricity needs. Our employees play a key role in driving grid innovation, protecting the system from threats, advancing the province’s energy conservation programs, and forecasting and procuring the electricity resources we’ll need in the decades to come. This is a unionized position that falls within the Market Operations Division in the Markets and Reliability Business Unit. The energy sector is rapidly evolving, offering exciting new opportunities for those who want to make a difference. 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. This is a promotion-in-place (PIP) affected role, candidates with lesser qualifications would be considered for a Assistant System Operator role.

Requirements

Requires a strong knowledge of electrical theory, power system design, operation and control, associated mathematics and computer applications to undertake system control and management of the IMO-controlled grid. Requires analytical and marketing skills, knowledge of technical writing to prepare reports, and oral and written fluency for effective communication.
This knowledge is considered to be normally acquired through post-graduate education beyond secondary school plus further extensive theoretical study of subjects pertinent to the electrical discipline and the specialty area of the work function.
The job also requires being NERC-certified.
Requires experience to acquire a full understanding of the Interconnected Power System Operations, of NERC, and NPCC guidelines; of Agreements; of Market Participant equipment capabilities, and technical Directives; of the Market Rules; of Market Participants; of the Facilities Description Documents, of Market Manuals and Market Procedures; of pertinent Station Data, and of all EMS-related software programs.
Requires experience with analytical studies and the application of PC operations including program management and organization of files and directories and various software.

Responsibilities

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.

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.
Immediately direct generation, reconfigure transmission or shed load to mitigate critical conditions and preserve the integrity and reliability of the BES.
Coordinate the operation of the ICG as per market rules, NPCC criteria, NERC standards and Operating Agreements.
Monitor/assess/validate/update Operating Security Limits (“OSLs”) used to maintain system reliability throughout the day.
Monitor/assess/implement/direct the operation of the ICG to maintain all equipment within the ratings provided by market participants, including day-to-day voltage control and power quality.
Monitor/assess/implement/direct items to provide Area supply, provide ancillary services, maintain pre- and post- contingency voltage, respect thermal and stability limits, implement control actions, and respect transmission capacity and tie-line capacity between the IESO and its interconnected neighbors.
Implement industry-based processes and procedures as required (e.g. Intertie Distribution Calculator (“IDC”), Transmission Loading Relief (“TLR”), etc.).
Recognize deficiencies/errors in displays and drawings and recommend and request revision.
Run system studies to determine the effect of different generation and transmission configurations upon the ICG. Provide recommendations to the Senior Operations Officer.
Create/check for accuracy/publish System Status Reports (“SSR”) for current day and next day to notify the market place of the status of the ICG and IAM.
