IESO Boilerplate

The IESO manages the province's power system so that Ontarians receive power when and where they need it. It plans and prepares for future electricity needs, and works with its partners to guide conservation efforts. A not-for-profit entity established by the Government of Ontario, IESO fees and licences to operate are set by the Ontario Energy Board.
