Will the Power Grid Hold up in this Week’s Heat Wave? With high temperatures in the 100’s for the next few days, few things are more important than air conditioning, and to have air conditioning there must be a reliable power source. KGVO News spoke with Jodi Black with Northwestern Energy and asked her how robust the power grid will be in the northwest as the entire region remains under a massive heat wave. “We are anticipating the rise in temperatures that will be moving from the west coast inland, and are coming our way into Montana,” said Black. “Our energy marketing team uses forecasts among the tools that they use to prepare for this kind of demand that we're anticipating. Northwestern Energy is anticipating this and preparing for it. We work throughout the whole year so that our system will continue to provide reliable service when demand is high and we are anticipating very high demand.”
