According to the Ministry of Energy, Ontario’s power generating facilities include:
- 5 nuclear power plants
- 180 hydroelectric stations of which 58 are connected to the grid
- 4 coal-fired generators
- 60 natural gas stations of which 19 are connected to the grid
- and a limited number of miscellaneous generating facilities (wind, wood, waste, etc.)
Ontario is part of an interconnected electricity "grid" known as the Northeast Power Coordinating Council (NPCC)
. It is a network of power plants, substations and transmission lines that cross borders, allowing Ontario to import and export power. This grid serves two purposes. First, it enhances the stability of the system. And second, it allows utilities to sell power to each others, thereby reducing generation costs.
