The Northwest Territories Power Corporation has been using more than seven times the usual amount of diesel to generate electricity in the North Slave as low water levels impede its hydroelectric dam system. The Snare hydro system is a series of four hydro plants that provide power to Yellowknife, Behchokǫ̀ and Dettah. The system usually generates about 98 per cent of all the electricity needed to power those communities, but this year — it's been a different story.
