When do peak electric usage periods happen?
Peak loads result when the overall demand for electricity in the community increases to the point that it reaches record levels. Typically, they occur on hot summer weekdays between 3 p.m. and 6 p.m. On these days, customers in the program are asked to curtail their demand for electricity for a three hour period. Columbia Water and Light can not anticipate the number of load shedding days expected during any one summer. Generally, an average summer will produce less than seven days in which load shedding is needed.
