Due to the rapid economic development, the electricity demand of Taiwan has been increasing year by year, which resulted in a constantly low reserve margin of electrical generation. Once increase the generation of electricity whenever needed, it would cause more resource consumption and environmental impact. In order to reduce the demand of new electricity and to achieve the goal of sustainable electricity, it is necessary to improve the energy efficiency. In light of this, many countries implement Demand-Side Management (DSM) program. DSM includes energy efficiency and loading management. DSM has been an effective means to capture zero-emission energy resources while satisfying the increased demand for electric power and reducing the need for new generation capacity and improve the energy efficiency, realize the saving of electricity and electric consumption, improve and protect the environment, and realize the efficient allocation of the electric power resource. The effective implement of power demand side management can alleviate greatly the shortage of power supply in these days, and it is necessary for sustainable development of economy. However, the DSM program in Taiwan mainly focuses on loading management, which limits its function on saving energy. Hence, the DSM program in Taiwan should switch to energy saving and raise efficiency in the future for creating a win-win situation, i.e. demand side (electric users) can reduce the financial expenditure, and supply side (electric provider) can avoid costs of developing new electric sources.An extensive literature has been conducted and a two-stage questionnaire was developed. In the first stage, the questionnaire was mailed to experts and the Fuzzy Delphi Method (FDM) was applied to confirm the DSM framework which includes 13 indicators. In the second stage, the Fuzzy Analytic Hierarchy Process (FAHP) was adopted to determine the weightings of different evaluation principles and criteria. The results indicated that the most important 5 indicators are “smart meters and digital services” (0.168), “Integrated Resource Planning” (0.118), “time of use rate” (0.111), “tax exemption and incentives” (0.111), and “promoting through energy service companies (ESCOs)” (0.084). The results also show that demand-side management, through appropriate incentives and regulatory measures, will have certain influence on the use and development of sustainable energy. It is hoped that this study will provide some insight for Taiwan Power Company to implement the most suitable DSM programs in the future.
