[cdn-nucl-l] RE: Darlington produces 20 per cent of Ontario's electricity



Title: Message
Hi Mike
 
Regarding "Darlington produces 20 per cent of Ontario's electricity".   In 2001 Ontario produced 152 038 GWh of electricity (Stats Can 57-001) and Darlington produced approx 26,000 GWh net to grid.  Thus Darlington contributed about 17% of Ontario's electricity, and operated at 85.6% capacity.  In 2002, Darlington operated at a higher capacity and produced (a preliminary and unofficial approximation) about 27,500 GWh net.  If Ontario's total production was the same as 2001 (note that the 2001 production was almost identical to that of 2000), then Darlington produced about 18% of Ont's generation.
 
In the latest data I have, for 2000, Ont produced 153 221 GWh, consumed 140 888 GWh and exported 5 990 GWh (Stats Can 57-001).  Presumably the remainder (153221 - 140888 - 5990 = 6340) is line losses, which works out to 4.1% (reasonable?).  If we assume similar values for 2002 (note that we imported electricity during the summer peak, but export it at other times), then Darlington produced about 26400 GWh (net after line losses of 4%) which represents 18.7% of the consumed electricity.  This is certainly approaching 20%.

Hi Adam:

All this talk of fusion, etc., and this article that got everyone started on this topic has me wondering a few things.
 
First of all, how do you generate electricity from fusion?  Because, and correct me if I'm wrong, I'm assuming that's the ultimate goal of ITER (to demonstrate that a sustainable reaction is achievable and, later, that electricity generation is possible).  Obviously the conventional steam turbines won't cut it (we can't even contain the plasma with conventional materials, so how could we use the heat to make steam?)  Would TEGs work at those temperatures? 
 
Secondly, the article that Jerry posted stated that "Darlington produces 20 per cent of Ontario's electricity. "  The IMO lists available capacity in Ontario at 29939MW, which may or may not include available imports.  So let's consider OPG alone.  OPG's website indicates them to have ~24600MW installed capacity, including Pickering A.  Darlington can produce ~3500MW, which by my calculations is at best 14% of OPG's capacity.  Since there are other generators in the province, notable Bruce Power, there's no way Darlington produces 20% of Ontario's electricity.  Any idea where the Star came up with this figure?  Would this be based on actual energy produced?
 
Cheers
Mike
