What makes this role exciting
The energy sector is rapidly evolving, offering exciting new opportunities for those who want to make a difference.
The successful candidate will posses a professional engineering license from Ontario and have extensive experience working with power systems. The Power System Engineer conducts engineering studies, analysis and application of specialized technology in the field of power systems in support of real-time operations, operations planning or planning activities. Supply analytical and technical support for policies, operating agreements, equipment specifications, operational and outage plans and system investments. Conduct model development, studies and analysis that:
-
- contribute to the production of Operating Instructions (including System Control Orders and on-demand limits);
- support IESO security, adequacy and operability obligations found in the Market Rules and in applicable NERC and NPCC reliability standards;
- assess the impact on reliability and validate performance of new or modified facilities impacting the IESO-controlled-grid;
- develop and update models, data and security applications for existing, new or modified facilities;
- support online and off-line security model management (models, data, and security applications); and
- support the coordination with neighboring entities on NERC, NPCC and regional market in the area of reliability matters.
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:

Assess Power System Change Role:
- Undertake System Impact, Technical Feasibility and de-registration assessments to evaluate the reliability and operability impact of a new or modified connection, or a disconnection, on the integrated power system using applicable IESO, NERC and NPCC reliability standards.
- Prepare reports containing the results of the study, any required system upgrades and connection requirements, and a recommendation for the IESO to issue a notice of approval or disapproval for the new or modified connection.
- Validate registration data based on information initially submitted for assessment. Re-assess the proposed connection if the registration data differs materially from the configuration or technical parameters that were used by the IESO to approve the new or modified facility.
- Provide support for regional and bulk power system planning, for preparation of evidence required by connection applicants to obtain the OEB's leave to construct and for inquiries from neighboring jurisdiction as they relate to connection assessments.
- Conduct technical studies to support the IESO's initiatives for evolving the policies related to the operations and evolution of the IESO-controlled grid and the IESO-administered markets.
- Support SPS/RAS classification processes on behalf of the IESO with external standards authorities.
Common Role:
- Support IESO security, adequacy and operability obligations found in the Market Rules and in applicable NERC and NPCC reliability standards.
- Support the preparation and delivery of reliability compliance evidence, including work procedures, RSAWs, market manuals, training material and participation in reliability audits
- Participate in task forces, as well as internal/external committees on matters related to the secure and economic operation of the IESO-controlled-grid. Represent the IESO on interconnection committees. Participate as assigned, as a representative of the IESO before regulatory agencies, etc. and endeavor to advance the interests of the organization in designated areas.
- Supply a consultative service to other departments and/or business units on matters related to adequacy, security and operability.
- Mentor and assist training of new and/or junior staff
- Exercise limited/periodic supervision over assigned staff on special projects.
- Sign or sign and seal documents as a P Eng. thus taking professional responsibility for one's own work.
- On occasion, sign or sign and seal documents as a P Eng. for peer review, or to assume professional engineering responsibility for engineering work performed by unlicensed staff.
- Perform other duties as required.
In a typical day, you will conduct detailed system impact, technical feasibility, and de-registration assessments to determine how new, modified, or retiring connections will affect the reliability and operability of the integrated power system in alignment with IESO, NERC, and NPCC standards. This includes analyzing technical data, validating registration details, and re-assessing projects when configurations or parameters change. Time is also spent preparing comprehensive reports outlining study results, required system upgrades, and formal recommendations on whether connections should be approved or denied. Additionally, the role supports broader system planning initiatives, responds to stakeholder and regulatory inquiries, and performs technical studies that inform the evolution of grid operations and market policies.
Currently, the Connection Assessments team is helping shape the future of Ontario's electricity grid by facilitating the integration of innovative and high-impact projects, including data centres, battery energy storage systems (BESS), and Small Modular Reactors (SMRs). These projects play an essential role in supporting growing electricity demand, enhancing system reliability, and advancing decarbonization objectives.
Additionally, as the first team to assess many emerging technologies seeking to connect to the grid, Connection Assessments operates at the forefront of industry innovation. The diverse nature of these projects presents unique technical, operational, and regulatory challenges that foster continuous learning, professional development, and opportunities to influence the evolution of Ontario's energy landscape while delivering customer-focused solutions.
