It's clear that a problem Canadian utilities or Canadian owners of transmission facilities have shared with U.S. owners of transmission facilities has been an under-investment in transmission for quite some time in both countries. Some of this is for regulatory reasons; the shift in models of regulation has in some sense left very unclear what the incentives for transmission investments are. I think this is an issue that needs to be addressed.
In terms of the structure of the grid, what we need to let emerge is what makes the most sense from a commercial perspective. Set up the regulations or the framework you want in place and then allow people to make decisions as to where reasonable investments make sense. In some sense, if the customers are relatively close, it makes more sense to have transmission investments working that way than to decide, for example, to use hydro power from Manitoba to replace coal generation in Alberta. So we need to think.
If we think of this as a security system argument, we need to recognize again that Canada and the U.S. are integrated in various bits within the electricity system. The best investment for consumers as a whole is where it makes most commercial sense, to strengthen reliability and to make power available at relatively low prices once the policy framework is in place.
