About IESO

The Independent Electricity System Operator, or IESO, is a government agency in Ontario responsible for managing the province’s electricity system. It ensures that supply and demand for electricity are balanced in real time and that the power grid operates reliably and efficiently. The IESO also runs Ontario’s electricity market, where electricity is bought and sold, and helps plan for the province’s long-term energy needs. This includes forecasting electricity demand, acquiring new energy resources, and integrating renewable energy and emerging technologies into the grid. The organization works with a wide range of stakeholders, including utilities, energy companies, municipalities, and Indigenous communities, to support a reliable, sustainable, and affordable electricity system. The IESO is headquartered in Toronto and plays a key role in shaping Ontario’s energy future.

Key Responsibilities

• Supporting the reliable operation and maintenance of Ontario’s electricity grid by monitoring system performance and coordinating maintenance activities for transmission and generation assets.
• Developing and implementing maintenance strategies and programs to ensure system availability and minimize disruptions.
• Participating in operational planning, including load forecasting, contingency analysis, and resource adequacy assessments to maintain system reliability.
• Collaborating with real-time operations, market participants, transmission operators, and planning teams to align operational and maintenance activities.
• Analyzing system data and preparing reports to support decision-making and regulatory compliance.
• Supporting outage coordination and restoration processes during planned and unplanned system events.
• Ensuring compliance with NERC, NPCC, and Ontario-specific reliability standards and grid codes.
