Does a Peak Alert signal a power shortage?
Not necessarily. Its possible the peak in demand could be an isolated event in our community, and a power shortage would likely come as the result of an entire region running at high demand for an extended period. We have not faced this situation in the Upper Midwest, but if demand growth continues to outpace supply we could see power shortages, which can result in rolling brown outs. This has already occurred in the eastern and western United States.
