Ontario’s electricity supply mix varies from day to day, but is approximately 50% nuclear (~10,000 MW), 25% natural gas (~5,000 MW), 15% hydro (~3,000 MW), 2% coal (~350 MW), 1% wind (~200 MW), and 1% other renewables (landfill gas, biomass, solar, etc). Wind and solar energy make up a very small FRACTION of what’s presently on our grid, even when generating at their full OUTPUT.

For greater clarity, the “supply mix” really only refers to the generation that we’re presently using in Ontario.

Our grid has a heafty margin of backup equipment connected and READY at all times, and those numbers are a little different: 33% of what’s connected to our grid is nuclear (~11,500MW), 29% is natural gas (~10,000 MW), 23% is hydro (~8,000 MW), 10% is coal (~3,500 MW), 4.4% is wind (~1,500 MW), and 0.4% is other renewables like landfill gas, biomass and solar (~200 MW).
