Infographic: Ontario’s Electricity System
The challenge of managing the electricity system begins with balancing just enough supply of electricity with the need for it on a minute-by-minute basis. There are many moving parts to the electricity system, all of which need to be carefully coordinated for the system to work.Ontario is committed to conservation and building strong communities, powered by clean, reliable and affordable electricity.
The province has many generators who use diverse and complementary sources of energy to provide reliable and affordable electricity. These sources are nuclear, hydro, natural gas, wind, solar and bioenergy.
Ontario’s five transmission companies move electricity at high voltages over long distances, from generation sites to local distribution companies and consumers.
Local distribution companies own and operate the distribution networks that take electricity from the transmission system or other local sources of generation and deliver it to consumers.
The role of consumers in the electricity system is changing. Consumers can actively manage their own electricity use and save on their electricity bills. They are able to shift their electricity use to periods of lower prices, adopt new technologies to use electricity more efficiently and even install technology that allows them to generate their own electricity.
Ontario has enough electricity to meet its needs, however consumers are encouraged to help reduce the demand for electricity through conservation. This helps to avoid the need for significant investment in new electricity.
