Abstract: Demand-Side Management (DSM) is the planning, implementation and evaluation of utility activities designed to encourage customers to modify the timing and level of their electricity consumption. Cost-effective DSM programs can create multiple benefits for all segments of society. Properly conceived and implemented, DSM programs can provide financial benefits to power companies, economic benefits to utility customers, and environmental benefits to society. This project started with a literature review of the essential factors for successful DSM development and the state-of-the-art techniques in cost-effectiveness analysis of DSM programs. The review was then followed by an examination of the electricity supply and demand situation in Hong Kong, and the local utilities' efforts at promoting DSM. This examination formed the basis in identifying the needs and opportunities of Hong Kong to adopt DSM measures. Cost-effectiveness analysis is an important tool in DSM planning. It plays a critical role in both the design of individual programs, and the screening and evaluation of programs. In order to help assess the feasibility and associated impacts of DSM options for Hong Kong, a user-friendly evaluation software model was developed. The model aims at giving a framework for the quantification of benefits and costs of DSM programs from various perspectives, such as of participants, of non-participants, of utility, of utility and participants together, and of society as a whole. It is hoped that the software model can offer a logical framework for evaluating DSM programs as well as communicating the decision situation. Moreover, with the help of the software model developed in this project, a quantitative assessment of DSM programs which have been actively pursued in Hong Kong was conducted. For example, the results indicated that although the current time-of-use tariff is a cost-effective means for promoting ice-storage air-conditioning system from all perspectives, the benefits to the participants are quite marginal and may not commensurate with the risk associated. In the concluding part of this project, the existing barriers to successful DSM development in Hong Kong are identified and recommendations to overcome them are also made.
