As one of the cleanest sources of electricity, Ontario's waterways provide many opportunities for renewable energy projects, and is a proven critical resource for the sustainability of the electricity system.

Water is used to generate electricity by harnessing the energy in moving water. The basic process is to take water from a river or lake and pass it through a tunnel or tube that includes a drop in elevation. The moving water then spins a turbine connected to a generator that produces electricity.


The status of individual contracted electricity supply projects within different IESO procurement programs is now available in the IESO Active Generation Contract List.
