Abstract: In Singapore, the electricity market comprises generation companies, transmission retailers and consumers. Electricity generation in Singapore is outsourced to privatized power generation companies to create a market and competitiveness in energy retail while electricity transmission from generators to consumers is controlled by the Government. The pricing of electricity varies upon balancing the supply and demand. At the consumers’ end, Contracted Capacity Charges and Uncontracted Capacity Charges are the two main concerns as part of the tariffs offered to contestable consumers. The purpose of Contracted Capacity is to stimulate better load management, thus avoiding an uncontrolled growth in demand. Thus, as the daily energy consumption in NTU is substantial, the Maximum Demand may exceed the Contracted Capacity limit at times resulting in an exceeded demand. This exceeded demand will only incur an unpleasant electricity price charge under Uncontracted Capacity. Therefore, it is only wise that preventive actions are put in place to reduce energy consumed at peak intervals where the demand exceeds the limit so as to have a more efficient energy usage and reduced energy costs. Therefore, a new maximum demand control method for load management is presented. Based on the nature of the available controllable loads, various objectives such as maximum demand reduction, energy saving and load shifting are formed in order to minimize the monthly total bill cost.
