The Yukon chamber actually hosted a series of about a dozen workshops beginning in October of last year looking at a broad variety of potential sources of electrical generation, including wind, geothermal, biomass, in addition to hydro and more conventional sources. The challenge we found is that our geothermal sources are somewhat limited and quite frankly, distant from our existing power grid.
We also have to factor in the costs associated with bringing any electricity generated from where the windmill is, or where the geothermal source is, to the power grid. That can be hundreds of kilometres of transmission wires, which of course has to be folded into the cost of the project. It's also, in the example of wind power, not on demand.
Quite frankly, about 100% of our hydro capacity today is being tasked to supporting environment, our electrical demand here in the Yukon. The oil and gas or the diesel generators that we currently have, that we're proposing to swap out with natural gas fuel generators, would be currently used only for backup if we have a hydro failure, or to address peak demand periods like when it gets down to minus 40 degrees here, and people are firing up their baseboard heaters.
