Thank you for being here today.
It seems to me, if I can summarize what I've heard, that if we want to move electricity or create green, clean electricity in provinces such as Alberta, Saskatchewan, and Nova Scotia—and under the new framework you'll be wanting to encourage cleaner electrical sources—there are two options. One is to facilitate the transmission of clean energy and hydro between British Columbia and Alberta or between Manitoba and Saskatchewan and Ontario, etc. The other is that we can develop more regional renewable energy sources; so Alberta would be, and is, developing solar and wind.
I just wondered if you could comment on two parts of that. One is just in the engineering part of it. What is the minimum ratio of the dispatchable type of energy the grid needs right now? Is it something that can change if we modernize the grid? Also, what are the relative costs of these energy sources: wind, solar, and hydro? Big hydro projects all seem to be fairly expensive. I know you talked about a study that was going to come up with some answers to this, but are there any kinds of ideas right now?
