I'd be happy to speak to that.
NAFTA in its current form has produced no impediment and if anything has been a facilitator of trade in electricity. As a commodity, it is tariff-free and has remained so, which has certainly eased our ability to continue that trading relationship with the U.S.
In terms of the opportunity, there are currently six different transmission lines proposed across the country to expand our interconnection with the U.S. to facilitate exports. There have also been some key decisions in the U.S., including in the U.S. northeast, to count Canadian hydroelectricity as contributing towards their renewable portfolio standards. This has been key, because it allows them to count what is clean—Canadian clean energy—as clean when contributing to meeting their own emission reduction goals. We see utilities such as Hydro-Québec, Emera, and others participating in bid processes in New England and elsewhere, seeking to expand those opportunities.
Obviously those will be hyper-competitive bid processes, but I think Canada has great strength, particularly because what we can offer is the firm capacity of such things as hydro to combine with the variability of other resources that states may wish to develop locally. Firming that product allows them to build a higher proportion of variable renewable energy than they would be able to otherwise. This is something we see in Manitoba in its interaction with the Midwest as well.
