The project that I referred to, the Taltson hydroelectric expansion project, is one that would expand the capacity at the Taltson power dam south of Great Slave Lake. It would provide hydro power to the Slave province, which is a geological province where the diamond mines are. It would provide hydroelectric power to the mines, which currently use diesel-generated power. The diesel I referred to is the fuel that is used by the diamond mines to produce their power for their operations. So by replacing that, it would reduce the need for a significant amount of fossil fuel.
