In a study of the effects of weather upon the consumption of electricity in a power network, it was found that large-scale load variations generally mask the effects of weather and make it almost impossible to obtain practical results from a comparison of the load data in their original form. A simple method is presented by which the effects of a seasonal trend and of major load shifts, caused by changing activities in a community, can be eliminated. This method makes it possible to analyze load data for possible weather effects, even though the consumer demand for electric power may change considerably during the period for which the study is being made.

** Based on part of a PhD Thesis, The Pennsylvania State College, Sept. 18, 1949.
