These alerts are available to most residential customers with at least 12 months of service who are registered with our Online Services portal.

You will receive an alert if your bill is projected to be 30% and $30 higher than usual. This projection is based upon your historical usage and whether the temperatures are higher or lower than last month. Alerts are sent halfway through your normal billing cycle. Receiving it midcycle allows you time to make energy-saving choices that will help reduce your bill.
