When I click the link, I only see daily activity. How can I view hourly activity?

From your dashboard, click on "History" and then "Usage History." In the Time Period section, click "View Hourly Electric Usage." You’ll be presented with a chart representing the most recent full days’ worth of hourly data. Under Hourly Usage will be listed hourly data for the past week. To view the previous week, click "Next Week." To return to the current week, click "Previous Week."
