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; and coordinating province-wide conservation efforts.

A director appointed by the Minister holds office at pleasure for an initial term not exceeding two years and may be reappointed for successive terms not exceeding two years each.
