The maximum demand curve represents a typical residential consumer and each bar provides demand in kW every 15 minutes. In this case it is appropriate to note that during the 24 hour period a large variation of demand occurs. This particular consumer has three periods in which the demand in kW exceeds the value of 6 kW. The largest of them is the maximum demand in kW every 15 minutes. For this consumer the maximum demand in kW every 15 minutes occurs at 13:15 and has a value of 6.34 kW.
In average demand, the energy in kWh consumed during a day is calculated during the 24 hour period the consumer consumes energy – kWh. The total energy consumed during the day is the sum of all intervals of 15 minutes. The total energy consumed for 24 hours by Consumer # 1 is 63.18 kWh.
The load factor is a term commonly used when describing a load. It is defined as the ratio of average demand to maximum demand. In many cases the load factor provides an indication of how utility resources are being used.
