RE:RE:Re PowerOld Article but it shows the intent (and obligation) of Yukon Energy:
Morrison explained that one way or the other, whether it's hydro, diesel generation or otherwise, Yukon Energy will supply the mine because the Public Utilities Act prohibits the utility from refusing customers who tie into the grid.
Victoria Gold will be responsible for building its own transmission line from the mine site to the power line running from Mayo to Elsa, but once it's complete, Yukon Energy is obligated to supply power, he said.
