Commonwealth Edison Co. (ComEd) and PECO Energy Co. (PECO), two of the nation’s largest public utilities, each reported breaking records for consumer power usage this week as heat waves continued to bake their service territories.
Illinois-based ComEd, which provides electric service to Chicago and surrounding areas, announced that consumer demand for electricity had reached an all-time high late Wednesday of 23,753 megawatts, which broke its previous record of 23,618 megawatts on Aug. 1, 2006.
A day later, Pennsylvania-based PECO, which provides electric service to Philadelphia and surrounding areas, announced that consumer demand had reached an all-time high late Thursday of 8,943 megawatts, which broke its previous record of 8,932, also set in Aug. 2006.
ComEd and PECO attributed the increased operation of air conditioners for the record high consumer power use figures. Neither electric utility reported any service interruptions due to the record demand.
