With the significant increase in the consumption of electricity over the past few years, it has been hard for electricity entities to keep up with the sudden increases in demand. The replacement and upgrade of substation transformers and associated equipment is very expensive and time consuming to obtain and install. Also the wanton use of electricity without understanding the consequences and its impact on the environment is negligent on the part of the individual. For the purpose of this project Demand-Side Management is any action taken to reduce the consumption of electricity supply to a customers premises, to assist an Electricity Entity in the stability of the electricity network. This leads to the principle that Demand-Side Management can be used to defer capital expenditure by attempting to average a feeder or substation load over a longer period and reduce the amount of peaks and troughs. As will be seen later in the report, air-conditioning load is one of the fastest growing domestic loads, with significant increases over the past 2 to 3 years. As a result the electricity networks are being overloaded due to the unexpected increase in electricity demand. There are many different methods of demand-side management mentioned in this report, most of these can be used to manage air-conditioner load, however the methods would not be acceptable to customers. After looking at various forms of demand-side management I believe that congestion pricing is the method that is most suitable and fair for managing customers airconditioning load. Congestion pricing operates similar to tariff control, however the difference is that electricity prices are increased during high demand periods. Voluntary Load Shedding should be encouraged amongst those industrial organisations that can defer their load times. As such congestion pricing and voluntary load shedding are two methods of demand-side management that need to be seriously considered by electricity entities. Irrespective of what type of demand-side management method employed, for demand-side management to be effective the customer must actively support it.
