In answer to the first part of that question, with respect to the availability of excess capacity in Quebec, we know there is some, but in actual fact that's the purpose of the open access transmission request and the system impact studies. We've asked them to study that and to identify exactly what the excess is. If we need more, then there will have to be an investment to build more infrastructure or upgrade infrastructure.
The way the tariff works is that up to a certain point, some increased infrastructure is allowed within the tariff, and after a certain point, the tariff would be increased by the amount that it would take to do the extra upgrades.
That's the purpose of the impact studies, and that's the information we're getting this year. We will be able to answer that question better when we get the information.
You mentioned small hydro and wind. I think if you look at it, once again, not only from Canada's perspective but from Newfoundland and Labrador's perspective, Newfoundland and Labrador have what we call an energy warehouse. The federal government has talked about an energy superpower for Canada, but we believe we have an energy warehouse.
This relates to small hydro in that if you look at our resources, look past the lower Churchill and the upper Churchill, add to that the extra potential for further hydro development in Newfoundland and Labrador, and add to that the wind potential, which is second to none. We've just displaced North Dakota as the best wind regime in North America, and we have the statistics to prove it. They were talking about a 40% capacity. In fact, we're at 43% to 45%. I don't think I have to tell that to anyone who has visited Newfoundland. We may not need scientific data to prove that, but we have it in any event.
If you look at small hydro and wind and the massive resource we have there, and an energy warehouse, that only goes to show why it is so important, from a transmission perspective, for Newfoundland and Labrador to be able to grow our economy and stand on our own two feet over the next 25 to 30 years. We have to get this transmission situation sorted out.
It's good for the country. It's good for the rest of the provinces, but also we have all this extra energy that's sitting there waiting to meet the growing demands of central Canada. So anything we do here is going to enable continued development for Newfoundland and Labrador.
We need a lot of power for ourselves, but to be frank, I can't envision a situation in which the amount of power we have available to export.... I don't know if we'll ever be able to consume the huge amount that we have. We're talking thousands and thousands of megawatts. We are going to look after our own needs first, no question, but I know, just from the numbers we're running, that we have the answer for a lot of this country, and it's sitting there waiting to be developed. Any transmission work we do is only going to enable the rest of that.
You also asked a question, I think, about enabling wind. Another competitive advantage we have in Canada—we have it in Newfoundland and Labrador, and other jurisdictions have it—is that if you marry hydro with wind, it's a true marriage made in heaven. When the wind is blowing, you just let it blow and use all that power, and you store your water in the reservoir. That's basically storing cash. And when the wind stops blowing, you have enough extra water to start running your turbines instantly, and you blow it down.
What you do, in essence, is take wind, which is intermittent, and you make it firm. You make it like a hydro project by marrying those two together. Any jurisdictions that have lots of hydro and good reservoirs are able to take this wind energy and make it really firm.
