There is a group at NRCan that's responsible for electricity generation and transmission, but I think the best people to help you with the question are those at the electricity association. I worked with them a long time ago on utilization, but I know they have groups on generation, transmission, and so on.
There are some very strong researchers, engineers, and people working on this area in hydro. I would look to the very active hydro companies in Manitoba, B.C., and Quebec. They are really active, not only in that area, but in the area of consumption and utilization, because they had programs. B.C. still has a very good program on energy utilization. So that is probably a good idea.
I'm not an expert. I know that when we went from AC power to DC power transmission we saved quite a bit. I was close to a couple of people who worked at Ontario Hydro when I was in Manitoba, and there are some people there who really know that subject inside out.
