Independent Electricity System Operator

From Open Energy Information

The Independent Electricity System Operator (IESO) works at the heart of Ontario's power system – ensuring there is enough power to meet the province's energy needs in real time while also planning and securing energy for the future. It does this by:

  • balancing the supply of and demand for electricity in Ontario and directing its flow across the province's transmission lines
  • planning for the province's medium- and long-term energy needs and securing clean sources of supply to meet those needs
  • overseeing the electricity wholesale market where the market price of electricity is set
  • fostering the development of a conservation culture in the province through programs such as Save on Energy
