Connecting Today.
Powering Tomorrow.

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.

Ontario's power system is operating reliably through the COVID-19 pandemic. Please check this site for updates.

Coronavirus (COVID-19) update

Ontario’s electricity system is reliable with adequate supply to meet our needs. The IESO has implemented controls to ensure the continued reliable operation of the grid and minimize risks to its employees and stakeholders. Currently, most non-essential IESO staff are working from home, and increased hygiene and physical distancing measures are in place to protect those employees working onsite. The IESO is not accepting visitors at our three facilities, and in-person engagement and meetings are no longer being scheduled. Where possible, meetings and events including engagement activities are being moved to conference calls or webinars. Registration information has been updated on the website to reflect this change.

Thank you for your patience and co-operation. Please contact customer.relations@ieso.ca if you have any questions.
