Reliable operation of Ontario’s electricity system depends on continually balancing supply and demand in real time. Gas generation plays a critical role in maintaining reliability because it’s flexible and can be dispatched easily when it’s needed most.
Explore how gas-fired power works and the important role it plays in Ontario Power Generation’s energy mix.
There was 0.6 terawatt hours of power produced in 2019.

Fuelling system reliability
Closing our coal stations remains one of the world’s largest actions to combat climate change. In the absence of coal, gas-fired power generation stepped up to play the ever-important role of ensuring system reliability with its own unique set of benefits.
- Flexibility — These stations can remain unfueled on standby for long periods of time yet be ready to quickly spring into action to help meet any spikes in Ontario’s energy demand.
- Enabling renewables — Gas also helps enable other important renewable energy sources like wind and solar which are intermittent sources that require backup.
- Regulating costs — Given its relatively low operating and fuel costs, gas power also helps keep electricity costs down for customers.
