Load profile management for demand side management action plan
Customer load profile is an excellent guide in implementing demand side management. This serves as a monitoring tool for in which action plan method is to be applied. Levelling the load profile behaviour of the customer load will maximize the use the utilities generation capacity thus lowering the load factor. This is usually done by shifting some customer loads from peak loads hours to off-peak hours. Alternatively, off-peak load hours can also be increased to reduce the company’s load factor.
PEAK CLIPPING
Peak clipping refers to the reduction of utility loads during peak demand periods. This can defer the need for additional generation capacity. The net effect is a reduction in both peak demand and total energy consumption. This is usually implemented by direct utility control of consumer appliances or end use equipment.

VALLEY FILLING
Valley filling entails building of off-peak loads. This may be particularly desirable when the long-run incremental cost is less than the average price of electricity. This is often the case when there is underutilized capacity that can operate on low cost fuels. The net effect is an increase in total energy consumption, but no increase in peak demand. This is usually implemented by creation of new off-peak electric loads that previously operated on non-electric fuels, such as overnight charging of electric cars and thermal energy storage.

LOAD SHIFTING
Load shifting involves shifting load from on-peak to off-peak periods. The net effect is a decrease in peak demand, but no change in total energy consumption. This is usually implemented by time of use rates and/or the use of storage devices that shift the timing of conventional electric appliance operation.

STRATEGIC CONVERSION
Strategic conservation refers to reduction in end-use consumption. There are net reductions in both peak demand (depending on coincidence factor) and total energy consumption. This is usually implemented by ensuring end-use efficiency.

Strategic load growth consists of an increase in overall sales. The net effect is an increase in both peak demand and total energy consumption. This is usually implemented by increasing energy intensity and/or the addition of new customers.
FLEXIBLE LOAD
Flexible load shape refers to variations in reliability or quality of service. Instead of influencing load shape on permanent basis, the utility has the option to interrupt loads when necessary. There may be a net reduction in peak demand and little if any change in total energy consumption. This is usually implemented by using Interruptible and Curtailable rates.
