The Ontario Energy Board (OEB) sets transmission and distribution rates, and approves the Independent Electricity System Operator’s (IESO) budget and fees. The Board also sets the rate for the Standard Supply Service for distribution utilities that supply electricity (commodity) directly to customers.
Independent Electricity System Operator
The Independent Electricity System Operator (IESO) ensures that sufficient electricity is available whenever and wherever it’s needed. It ensures 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; and
fostering the development of a conservation culture in the province through programs such as Save on Energy.
