Ontario's Independent Electricity System Operator

System Control Room

The IESO manages Ontario's electricity system and operates the wholesale electricity market. It forecasts the demand for electricity and ensures that there are available supplies to meet that demand.

More than half of all electricity consumed by this province is paid for at wholesale rates. Most low-volume consumers, however, pay regulated rates that are revised every six months, based on market and contract prices paid to generators.
