In contrast, we have 13,009MW of nuclear*, which produced 91,700,0000MWh in the same timeframe, which results in ~7,050MWh per MW of installed capacity.
*We are down a unit at Darlington right now for refurbishment, though I believe it is still factored into the generating mix, despite its output not being present.
OVERKILL, the standards for reporting Capacity factor are on installed capacity. So a Unit in Shutdown is still counted as a zero.
So with 8760 hours in the year, the 13,000MW COULD have produced 113,380,000 MWh, and produced 91,700,000....a capacity factor of 80.5%...about what our coalers do following the market (note that load following reduces capacity factor as you are not SCHEDULED to deliver those MW...still "available".
The solar capacity time 8760 is 3,328,800 MWh, while 460,000 actual generation gives a Capacity factor of 13.8%...yes, my 25% is Oz, not Canada, so you need to increase by at least 50% numbers that I gave (panels, not batteries)...
I see what happened. They reported it because the unit was active until October of 2016, which is the year those figures are from. Our actual supply mix is as follows:
1. Bruce Nuclear - 8x Units - Total installed capacity 6,384MWe NET (annual output roughly 48TWh)
2. Darlington Nuclear - 4x Units - Total installed capacity 3,512MWe NET (annual output roughly 26TWh)
3. Pickering Nuclear - 6x Units* - Total installed capacity 3,094MWe NET (annual output roughly 20TWh)
Which gives us 12,990MW of installed capacity and 94TWh of output, a figure we've hit in previous years, which puts capacity factor at 82.6% average. The average CF factor for Darlington is listed as 83.83%, Pickering's is 73.85% and Bruce is 85.17%.
*Pickering is an 8-unit site but two units are permanently shutdown.
And yeah, northern climates and solar take a BIG hit as you can see
