ONTARIO’S ENERGY SUPPLY MIX FACTS
• Each generation type has a role in Ontario’s supply mix.
• Nuclear and large hydroelectric plants provide ‘baseload generation’ which means
they operate at all times.
• Sources like small hydroelectric plants get used when the demand for electricity increases.
• Wind and solar are ‘intermittent sources’ –
they can only generate electricity when the
wind blows or the sun shines.
