This graph shows the daily usage of all Glasgow EPB Customers. The blue line represents the peak monthly usage, when the rates charged by TVA are at the highest. By hovering your cursor over the line you can see the time of the peak and the usage during the peak. The overall goal is to keep the peak as low as possible. Each customer can help control this peak, and their own bill, by watching when the purple line (representing today’s usage) on a peak predicted day. At that time reducing your electric usage will mean a substantial savings on your individual bill. To see a similar graph for your own home or business, just go to
