For a minute I'll build on something Mr. Coupland said. When you have your renewable resources, as we do in Alberta, as most economically coming from wind and solar, and you have to deal with the variability but you want more energy from renewable electricity, the low-capacity factor—30% or 35% in the case of wind and up to 20% in the case of solar—means you are going to have to over-install capacity. When that over-installed capacity is producing, you are likely to have surplus.
There are really three possible ways to deal with the surplus. First is to curtail it, second is to store it, and third is to send it over to your neighbours. Again, that can be a mutual benefit over a wide geographic area. The two components where I think the federal government can help are in investing in infrastructure to make it happen and encouraging the co-operation between entities to make sure the transactions can occur and be expected to occur in an economic manner.
