First, as to the retirement of an older plant, I'm really referring to thermal generating plants as well, particularly coal-fired plants. Probably around 20% of that stock would be available for retirement around the 2020 period. It does vary across Canada. It depends on the vintage of the stock. But it's something of that order. We're looking at substantial billions of dollars of reinvestment as an industry to replace that capital stock.
Of course, the idea is to replace that capital stock with the best available technology of the time. That's one reason that we as an industry and as a company are working on IGCC as being that next technology, including carbon capture, not carbon-capture-ready but including carbon capture. I'd be happy to come back in 2009 and tell you the results of our feed work for that project and the likelihood of that project then being constructed. That's why we're very interested in participating with ICON in the carbon capture and storage piece, because without that carbon capture and storage piece, the IGCC is just not as effective.
