It depends on the distance. Mr. Nicholson may have examined that more closely in his article on the deployment of wind power. Regardless, there's no doubt that the challenge is figuring out how to replace fossil fuels. The fact remains that, if you take into account Hydro‑Québec's infrastructure, the company has more than a thousand kilometres in lines connecting the major production centres to the major centres where the energy is consumed. It is therefore possible to build transmission lines at a reasonable cost. The same goes for the transmission of energy between Churchill Falls and the Montreal market. It is therefore possible.
The availability of offshore wind is really something because it ensures a fairly steady supply, thereby reducing storage requirements to balance out variations in offshore supply.
However, all of that requires a conventional power grid once the offshore power has been generated. To justify these projects in eastern Canada, people are talking a lot about green hydrogen, ammonia and other elements, which lack adequate markets, cost a whole lot and are very uncertain.
I think it would be very tough to carry out projects with a 25‑year horizon without a real economic plan that is sound.
