Author Power generation in ON is a fiasco shared by both parties. Each has done their share of damage over three governments. Nuclear generation with construction faults in cooling. This happened all over the US too. Global warming fouled up their cooling abilities therefor their out puts. You see the same scenarios in Europe where rivers are too warm to provide the design cooling.
John Clark When faced with overheating because of a lack of cooling mechanisms (water lake river etc) the power operator will cut back the output. This brings on brown-outs ,black-outs etc. This in turn means less profitability for the Generator and possibly subsidies from the government depending on which markets they are hooked up to the purpose being to cover the shortfall in their own generation. Once up and operating the power generation is a resource more than an industry.
