126. As in Table 1 2 the accumulated energy the power load profile of Figure 1 7 is 14 92 kWh Demand is also a time based value The demand is the average rate of energy use over time The actual label for demand is kilowatt hours hour but this is normally reduced to kilowatts This makes it easy to confuse demand with power but demand is not an instantaneous value To calculate demand it is necessary to accumulate the energy readings as illustrated in Figure 1 7 and adjust the energy reading to an hourly value that constitutes the demand In the example the accumulated energy is 14 92 kWh But this measurement was made over a 15 minute interval To convert the reading to a demand value it must be normalized to a 60 minute interval If the pattern were repeated for an additional three 15 minute intervals the total energy would be four times the measured value or 59 68 kWh The same process is applied to calculate the 15 minute demand value The demand value associated with the example load is 59 68 kWh hr or 59 68 kWd Note that the peak instantaneous value of power is 80 KW significantly more than the demand value Figure 1 8 shows another example of energy and demand In this case each bar represents the energy consumed in a 15 minute interval The energy use in each interval typically falls between 50 and 70 kWh However during two intervals the energy rises sharply and peaks at 100 kWh in interval number 7 This peak of usage w
