This estimate is very liberal. The asaTsnption is made that every house in the village will be wired for electricity. This condition will not exist* A second assximption is made that at dinner time and throu^ the early hours of the evening, each one of the ninety residences will be burning four twenty-five watt tungsten lamps. This community is composed of farmei^ - accustomed all their lives to kerosene lamp light and most of them will probably be satisfied with one light in the dinning room, one in the kitchen, one in the sitting room and one on the porch; ^ich will all probably burn during the peak hour. Other lights in bedrooms, bar»i^,etc,, will burn at off-peak-hours. However - a few cases of extravagance in fixtures, etc., will rapidly bring up the average - so that it is good practice in estimating the load for lighting the residences in a village of this character to use this figure of 100 watts per residence. The estimate of 150 watts central station capacity for business houses is very fair - when consideration is taken of the type of business establishment tsrpical of the town. There are but few concerns in the town which are progressive enou^ to illuminate their stores in a modern manner. In these few stores, for estimating pur- poses, the figure of one watt per square foot may be used; while in most of the stores it is safe to figure that a light will probably be used in each window with additional lights spaced ten or fifteen feet apart down the center of the store. Each church will present a separate problem, and an accurate estimate of the load which they will supply can only be made after detailed study of each has been made. However, the figure of 1500 watts for each churoh is close enou^ for determing the central 3.
