The Independent Electricity System Operator (IESO) works at the heart of Ontario's power system. The IESO delivers key services across the electricity sector including: managing the power system in real-time, planning for the province's future energy needs, enabling conservation and designing a more efficient electricity marketplace to support sector evolution.
Engaging the Sector
The IESO regularly seeks input from stakeholders and community representatives on initiatives that affect them. We do this through a variety of forums, including the Stakeholder Advisory Committee whose members represent interested energy sector parties.
The August 23 Stakeholder Advisory Committee meeting welcomes Michael Cleland with the Positive Energy Project to discuss the University of Ottawa’s efforts to strengthen public confidence in energy decision-making. The agenda, materials and registration details are now available.

Southern Ontario is expected to experience a partial solar eclipse on Monday, August 21, 2017.
The IESO has been actively monitoring weather and demand forecasts for this celestial event to ensure smooth operations for Ontario’s bulk power system. The IESO will be ready to respond to changes in demand and generation output to ensure reliable service for Ontario consumers.
