Yes, certainly.
That's a big part of the study. I spoke to it a little when I spoke to the last slide in the annex of the deck. The key places where we see opportunities for interties are between B.C. and Alberta. There are two different locations where there are potentials for interties there. In some cases, these are simply strengthening existing capacity, so you may have an existing line but it doesn't have sufficient capacity to support the ambition of export that you might seek to achieve. The other place is between Manitoba and Saskatchewan. There are some opportunities, given that Manitoba is hydro-rich and Saskatchewan is currently, to some degree, coal-dependent and having ambitions to transform towards renewables.
If we look at the Atlantic provinces, they are interesting because they are all, broadly speaking, quite close together. They have a number of existing interconnections, but there are areas where reinforced connections or potential relatively small new connections can actually build out a grid wherein you can do system-wide planning and balancing of electricity resources across the region. There are specific examples there as well. Those specific lines are the subject matter of the studies that we are currently undertaking. When those reports come out in early 2018, you'll be able to look at the greenhouse gas cost per tonne of each of those different options. That, we hope, will support the next level, which is the policy dialogue and the political discussion that needs to happen around advancing any one of those specific projects.
