Where is my Electricity Coming From at this Hour? (if I live in Ontario)

Link to this chart


CO2 avoided: Based upon the CO2 emissions from coal for an equivalent energy output, assuming: 0.85 tonnes of CO2 per MWh(e) from coal, 0.50 tonnes CO2 per MWh(e) from natural gas and “other” (assuming natural gas at the Lennox station as the main contributor), and zero tonnes CO2 per MWh(e) for wind, hydro, and nuclear.

# homes supplied: This is an illustrative estimate of the number of homes that could be supplied by the specific power source, based upon an average electricity monthly domestic usage of 972 kWh per home (source: Ontario Power Generation). In practice only about 30% of electricity production (in Ontario) is for residential use; the majority is for industrial and commercial customers.


Capability: The maximum amount of power (in millions of watts, or “Megawatts”, MW) that was capable of being produced by the unit in the last hour.

Output: The amount of power (MW) that was actually produced by the unit in the last hour.
