We face some problems because we operate cross provinces, whereas most of the system operators today in Canada are operating only in their jurisdiction. B.C. Transmission Corporation operates B.C., Alberta System Operator operates Alberta--so every province has just that province, in terms of operation.
We have to do reliability coordination for the Maritimes, so we have to interface with Nova Scotia, Prince Edward Island, New Brunswick, and northern Maine. We have four different tariffs, and operationally we would have a more efficient region if we had one marketplace and one dispatch across the region. That's one. We don't have that. We have parties that take advantage of the tariff for some things but then stay outside the marketplace for others. So we have people doing a mix of things, and we don't get the most economic solution for the region because essentially there are vested interests in each province and they're looking after their particular interests.
One is on a transmission tariff. How do you come up with a tariff that covers across the regions? You need to have the regulators and the governments in each of the regions accept that that's a reasonable approach in order to recover the costs of the use of those assets across the region. We have not been successful in getting an acceptable maritime approach to do that.
