I think the short answer to your question is yes. Any increase in transmission capacity benefits the system as a whole and benefits the companies who are prepared to use the system to lower emissions. You're quite right that today TransAlta already moves electricity into B.C. It's stored there in hydro capacity and then returned back to the system. So it's a very efficient way of maximizing the efficiency of fossil generation and using the attributes of hydro.
We would certainly say that transmission growth is an important element of any effort by the electricity sector to manage its emissions. At the same time, electricity markets in Canada are still quite regional, so it is not a small challenge to think about growing transmission capacity across the entire country. But it is a long-term opportunity that we should be studying quite carefully.
