Electricity Investments Help Ontario Meet Summer Power Demand

Here's an interesting tidbit.
Ontario produced about the same amount of electricity, at peak yesterday, as was being produced in 2006.
It did so with an average contribution from coal, and the Lennox plant, of 15% between 9 am and 9 pm, peaking at 4246MW at noon.

That left about 21000MW of other 'cleaner' production. Ontario demand, annually, is higher than 21000MW 2-4% of all hours.
Which is why we can reduce coal use by a lot, and yet the last cut will be painfully expensive.
