Accumulated debt is any usage registered on your meter after your credit has run out and power remains on. Accumulated debt may occur during Friendly Credit hours, emergency credit, Excessive Heat Warnings and holidays. This amount can be found on your SRP M-Power app. A purchase should be made in an amount that will cover any accumulated debt, as well as additional credit, to ensure there is no interruption in service. When a purchase is made and then loaded to your meter, the amount of any accumulated debt will be subtracted from the value of the purchase that is loaded.
