At the utility scale, the largest scale, we see a time in the next few years when it will be competitive on costs with new natural gas and new wind, for example. Literally it's as good as here now, today.
At smaller scales, we're a few years out for commercial and maybe five, seven, or eight years for residential, depending on which province we're looking at.
When we look at more distributed forms of generation, it becomes increasingly difficult to compare on a levelized cost—the price on your bill to the price on your roof—because when it's on your roof, you don't have to pay for any of the wires to transmit it and so on, so it's a little bit of a different value proposition.
To make a long story short, it's becoming increasingly more cost-competitive than I think anybody would have imagined several years ago. Because the time at which it is so cost competitive is so close, it's really time to start preparing with our utilities, with our power infrastructure, and so on, so we don't end up with redundant infrastructure that's not appropriate for the supply mix of the future.
